AI Thread Summary
The discussion centers around finding a reliable, free antivirus software, with users expressing dissatisfaction with AVG due to false positives. Alternatives like Avast and Avira are mentioned positively, while concerns about AVG's newer versions and their heuristics settings are raised. There is a debate about the definition of "free" software, with some arguing that AVG and Avast, while free for personal use, do not respect user freedoms as defined by the free software movement. The conversation also touches on the evolving nature of computer security, the necessity for constant updates in antivirus software, and the distinction between free software as a cost-free option versus software that respects user freedoms. Users share personal experiences with different antivirus programs, highlighting the importance of effective virus protection and the frustrations with false positives. The thread concludes with a philosophical discussion about the value of free software and the implications of using proprietary versus open-source solutions.

Hey all,

What is the best Anti-Virus that is 100% free? The new AVG is a piece of crap. I get fake positives where as I know for sure my computer is clean. I have nod32 and I like it but it's not free and my trial is almost up. I have to find a free program that is good and no fake positives. Can anyone help me find one? Take care everyone.

Avast!

Thank you for your reply. I will check it out now!
 
I say AVG, but I've heard great stuff about both Avast and Avira as well.

Is there an option to turn off heuristics? That would reduce the number of false positives.

I am not sure but is there? If there is, I would bet I go back to AVG. I miss 7.5 there was no false at all with that version. It became with 8.0 and 8.5 and so on.
 
AVG is still the best. I've had no problems with the new version.
 
I know, they tried to make it look fancy and all it does is piss me off. I don't get any false positives, but I've got dialup so I'm naturally slightly less prone. Especially the updater makes me mad, where as on the last version it would just update when I got on the net.
 
Really? No false positives guys? nod32 scans my computer with no threats but AVG gives me threats.

Alright, I found something but NOT sure how to do it:

http://answers.yahoo.com/question/index?qid=20080511134332AAEl2fO

The part I am not sure about is: You need to go to Tools > Advanced Settings, and then under Resident Shield go to Exceptions and add the path that ePSXe is in.

Where do I find the path? ePSXe? Never heard of it.
 
  • #11
If anything, a false positive is GOOD, cause its saying something that your other scanner can't.
 
  • #12
Be aware that if you use an AV program that quarantines suspicious files, it ignores the files that it has locked away, but other AV programs might "see" those suspicious files within the quarantine and give you a positive. In this case, you are not getting a false positive from the second scanner. It truly does "see" the string of suspicious code, but does not recognize that the first scanner has quarantined the file containing that code.

I use AVG Free and like it just fine; it's worth way more than what I paid for it.
 
  • #14
I've used AVG for years, never had a problem...

.. side note, where I work I get McAfee for free but I still use AVG.
 
  • #15
There are no free anti-virus software packages. This is mostly due to two reasons:

1) Computer security evolves so quickly that any general scanner must have a constantly updated database of known threats.

2) The demand for anti-virus comes from users of MS Windows, who presumably do not care about software freedom.

Where do I find the path? ePSXe? Never heard of it.

ePSXe is an emulator for the original playstation game console.

Avast! is free and the virus definitions are updated daily - much more responsive and up-to-date than Norton.

What? The demand for virus protection has nothing to do with being a Windows user, Mac has virus' also. And how does a MS user not care about "software freedom"? {software freedom...? I assume your referencing open source apps ?} Do you not care about "automobile freedom" because you paid for your car?? That was a dumb comment.

Macs have fewer viruses though...

I LOVE open source! I love the feeling of finding a fully functional, cool, useful program for FREE.

Free != no cost

http://www.gnu.org/philosophy/free-sw.html"

Avast! is free and the virus definitions are updated daily - much more responsive and up-to-date than Norton.

Avast is not free! It is provided at no cost for non-commercial use.

Ha ha, yeah, I think Crosson didn't even bother to read the OP or any of the posts...

I read the other posts, and I was blown away that other folks think things like AVG and Avast provide freedom to users.

AVG is free, I'm sure there are others as well.

AVG is provided at no cost for non-commercial use, it does not grant freedom to the user in any significant way.

What? The demand for virus protection has nothing to do with being a Windows user, Mac has virus' also.

Neither MS Windows or OSX are free software, so the point of my comparison is still valid: users of these operating systems do not care about their freedom, and so there are no free anti-virus products.

Besides, security packages on a UNIX system bear little to no resemblance with anti-virus scanners for windows, and most 'anti-virus' products sold on the Mac on marketing scams, very ineffective in real world use (exploits are rare, and an exploit being caught by one of these is rarer still).

And how does a MS user not care about "software freedom"?

You have no way of knowing what MS Windows is doing to your hardware! You gave them complete control of your machine :(

{software freedom...? I assume your referencing open source apps ?}

No, open source apps can be released with unlimited restrictions.

Do you not care about "automobile freedom" because you paid for your car?? That was a dumb comment.

This is ironic, because the old joke on Usenet was that any comment about computers that involves a car analogy is automatically a dumb comment.

To anyone who thinks I am being pedantic, or arguing semantics, you should know the history behind the free software movement and decide whether you support corporations or individuals.

Whoa man, calm down, there's nothing to get all worked up about here.

Most people consider "at no cost" to be "free".

True, and the company that wrote and maintains Avast has a right to expect that people who use it in a business setting (to make money, duh!) should pay for their copy. It's nice of them to distribute it free for personal use, and it helps keep the overall level of virus attacks suppressed so they are not fighting fires all the time. I have used NAV and the timeliness of their responses to new threats was disappointing.
 
  • #24
I really HATE people that make viruses, cause its so cowardly. I have high respect for hackers (some of them, mainly grayhats), especially when you read the Hacker's Manifesto.

Physicsforums is a very smart place, so I was surprised to see that AVG and Avast were being called free software. This conflicts with the usage of the term by the free software movement, which is a social and intellectual movement that has brought us the GNU/Linux operating system, the Mozilla firefox internet browser, openOffice, VLC Media Player, etc.

In general, freedom is something that people get very 'worked up' about. I am 'worked up' because I want you all to learn about the free software movement so that you can be free.

Here is a dystopian short story:

http://www.gnu.org/philosophy/right-to-read.html

Most people consider "at no cost" to be "free".

I agree that this is normal usage, but the free software movement is very important and they encourage us only to use the term 'free software' in reference to freedom.
 
  • #26
Yeah, well as long as I'm using Windows (I am making a FREE Ubuntu computer...BTW) I need virus protection, and I'm going to use a free one (I use free, deal with it...).

Believe me, I do use Firefox, openOffice, etc.

binzing said:

Why would you do this? Don't you understand the purpose of the free software movement, and don't you want to help it to achieve this purpose?
 
  • #28
I understand the movement, but unfortunately free programs don't yet have everything I need, and as I am not a programmer, its not like I can actually edit these open source programs to better fit my needs and likes.

I use it because it's how I speak, and it makes sense to do so. Most people, (even diehard Open Sourcers) wouldn't get in such a huff over symantics. Calling only true blue Open Source programs "free" isn't going to further the movement, neither will correcting people every time they say something is free, when, according to you, they should say "available at no cost for non-commercial purposes".

Let's support the people who supply alternatives (free for personal use) instead of blindly demanding that all software be free and insist that we should boycott software that doesn't meet your standards for "openness". That's ridiculous, and it's not going to happen. Programmers have to eat, too. I made my living for over a year writing custom application software for business that needed applications that were not available commercially. Believe me, I would not have wasted my time writing and giving away free software, and I am grateful for the people who make software available free for personal use while deriving their income from businesses.

binzing said:

So use a non-free program like AVG, or Avast Anti-Virus. These are available for personal use at no cost.

and as I am not a programmer, its not like I can actually edit these open source programs to better fit my needs and likes.

But someone else could, and so you get software that is much better suited to users needs.

I use it because it's how I speak, and it makes sense to do so.

Even when you are given a good reason to change?

Most people, (even diehard Open Sourcers) wouldn't get in such a huff over symantics.

That just shows how little you know about the free software movement.

Also, I have already said that open source is only one of the requirements for software to be free, not all open source software respects the freedom of the user.

Calling only true blue Open Source programs "free" isn't going to further the movement, neither will correcting people every time they say something is free, when, according to you, they should say "available at no cost for non-commercial purposes".

Well then I guess you understand how to further the movement better then the man who founded it, which would be great for the community considering the progress that he has already made.

Let's support the people who supply alternatives (free for personal use) instead of blindly demanding that all software be free and insist that we should boycott software that doesn't meet your standards for "openness".

That's fine, if you use MS Windows and you want a anti-virus scanner (which I recommend against) then I recommend Avast AV first, and AVG second. I don't think the expensive alternatives do a better job.

I just object to calling AVG and Avast '100% free' when they do not respect the freedom of the user!

I made my living for over a year writing custom application software for business that needed applications that were not available commercially.

Imagine if everyone who did this released there code as free software. There is no argument that this would hurt sales, since the software you wrote is not availible commercially, but it very well could save 9-12 months of effort for someone else doing a similar task across the world.

Believe me, I would not have wasted my time writing and giving away free software
I hope that now you see that time would have been saved, if not for you then for other people, if the software that you wasted your time writing had been released for free once and for all. Very ironic.

and I am grateful for the people who make software available free for personal use while deriving their income from businesses.

That's fine, but wouldn't it be even better if they released in a way that respected your freedom?

You find it ironic that I needed to be paid to spend weeks developing custom software for clients that needed apps that were not commercially available? I should have devoted weeks at a time to help make their businesses more efficient and profitable for free? That's ridiculous. You should try writing software full-time and giving it away for free to see how that works for you. Unless you are sponging off someone else who has a paying job, you aren't going to be in business very long.

turbo-1 said:

That you did this without seeing the value of free software, is what had struck me as ironic. By being open source and free, you get collaborators all over the world who are using the software for their purpose but also contributing their improvements to the core packages back upstream, for everyone else to benefit from, including you.

I should have devoted weeks at a time to help make their businesses more efficient and profitable for free?

I am by no means saying you should work without pay, that is absurd. You are mistakenly assuming that people who write free software do not get paid, but this is false.

You should try writing software full-time and giving it away for free to see how that works for you. Unless you are sponging off someone else who has a paying job, you aren't going to be in business very long.

I understand your pragmatic argument, but I am not asking you 'to write software and give it away free.' I am saying that if you support the goal of the free software movement, which has brought us firefox, linux, etc, then you should respect their guidelines for the term 'free software.'

Who here called them "100% Free"? Its in the title, we didn't use it once. Technically, yes, they ARE 100% Free...Maybe not for the whole program, but enough to satisfy most users...

Who says turbo didn't do that? He never said that he kept it to himself, or charged people for it.

Explain this whole notion of how software, open source, closed source, what have you, violates your "freedom" to begin with...

Crosson, I was writing software in the mid '80's. There was no Internet and no pool of collaborators. If you can find a way for me to get paid for writing code for free software, please steer me to it. I'd be thrilled to get paid to write free software. There is no free lunch.
 
  • #35
That's what I was guessing too Turbo, and back then everyone had to write software (no doubt yours was more complex to get paid for it), like teachers, they had to learn how to program software for the Apple IIes and such.
 
  • #36
I wrote applications in dBase and compiled them afterward so they would run faster. I only charged the businesses for my time, and I always gave them the uncompiled source-code for free so that they could hire someone else to modify the programs if necessary. I had no complaints and my business was growing very quickly through word-of-mouth, but I was burning out - sometimes coding 14-16 hours a day. I passed that business on to another programmer (with my entire client list) at no cost to him and moved on to a job that allowed me to work more reasonable hours.
 
  • #37
Hey Turbo-1, I think I understand your point of view.

I was writing software in the mid '80's. There was no Internet and no pool of collaborators.

There was an internet, and the free software movement was already underway, but I agree that free software was not a choice for your job back then.

If you can find a way for me to get paid for writing code for free software, please steer me to it. I'd be thrilled to get paid to write free software.

Here is a place to start:

http://www.fsf.org/resources/jobs/listing

There is no free lunch.

In a sense you are right, but in 2008 I can use my computer hardware with complete freedom, and no cost.
 
  • #38
Completely disregarding what I said, eh?
 
  • #39
What part of my hardware am I missing out on using windows? What exactly is being restricted? Is there some feature I am not getting that I could with linux?

Im not being an *** either, I am serious. Is it because windows/mac limits an independent applications access to hardware and core-operations? I had an old sunos system. My old P2 was running at any given time Linux (redhat 5 i think), Beos, and some other one i couldn't remember. Basically at the time i was extremely disappointed due to the lack of developed drivers for the most basic of hardware, and so I went back.

I love openoffice, firefox, etc and use them daily. (more like by the second). And even started developing (or trying to) my own plugins for firefox. But I still feel its rare to find a decent product that has had that much effort put into it like those. Most "free" applications seem to fall into disrepair and end up as ditched projects.


On a side note about "free" I still feel like its OP usage was ok. Here comes a delicious analogy.

If someone offers you an oreo, and you take it, was it a "free cookie"? Or was it not truly free because you were not offered the freedom of choice of whatever you wanted (a softbatch most likely). Depends on how you look at it. Maybe it wasn't a free cookie, but it was a free oreo.

You didn't get "free software" you got "a free limited usage non commercial virus scanner".
 
  • #40
He was using the word "free" in a different sense:

[PLAIN]http://www.gnu.org/ said:
What[/PLAIN] is Free Software?
“Free software” is a matter of liberty, not price. To understand the concept, you should think of “free” as in “free speech”, not as in “free beer”.

Free software is a matter of the users' freedom to run, copy, distribute, study, change and improve the software. More precisely, it refers to four kinds of freedom, for the users of the software:

The freedom to run the program, for any purpose (freedom 0).
The freedom to study how the program works, and adapt it to your needs (freedom 1). Access to the source code is a precondition for this.
The freedom to redistribute copies so you can help your neighbor (freedom 2).
The freedom to improve the program, and release your improvements to the public, so that the whole community benefits (freedom 3). Access to the source code is a precondition for this.

It is choice to blame a diagnosis and accept your shortcomings, or instead you could work and practice to improve your own ability to use language.

I'm sure there's plenty of open sourcers (the one's who actually do this stuff) who aren't as literal

Not everyone is as careful in their usage as I am, but I am far from being alone on this issue:

http://www.gnu.org/philosophy/free-sw.html

Since when does software, or the people that make it, give a damn about the "freedom" of the user?

This is one of the core reasons why people release software under free software licenses.

Here is a website from a free software programmer who is creating a CD Ripping / Encoder application. When you read that, do you see that he cares about the freedom of the users?

And this man is? Yourself?

I was thinking of Stallman, the man who "in 1983 launched the GNU Project to create a free Unix-like operating system, and has been the project's lead architect and organizer."

http://en.wikipedia.org/wiki/Richard_Stallman

Stallman thinks it is a good idea to use the term 'free software' only for software that respects the freedoms of the user, as I have recommended in this thread.

You recommend against preventing viruses, therefore you want people to get viruses? Cause, unlike human lives, neither virus programmers, nor AV companies care about how many computers get "killed"...

No, I said I recommend against virus scanners. To prevent viruses, I suggest getting educated about computers. Configuring a firewall and using smart practices is sufficient protection even for users of Windows XP. There really is no way to get a virus other then by making obvious mistakes.

What did you learn from the last virus you had?

As turbo said, there are PEOPLE who RELY on this for INCOME, it is they're LIVELIHOOD. Now, if you have the money to pay all of the programmers better than they're closed source, corporate employer, do it! By all means.

I don't, but other people do, which is why you are using firefox, openOffice, etc. Mozilla and IBM both PAY people who RELY on INCOME.

I don't even understand why you are arguing about whether people can make money from free software. The fact is that they do.

What part of my hardware am I missing out on using windows? What exactly is being restricted? Is there some feature I am not getting that I could with linux?

Why doesn't windows recovery have an option to save an image of my hard drive as .ISO and restore from it at a later time? A perfectly exact image, that I can burn on a series of DVDs, so that as soon as my main windows partition goes haywire I can put the disc in the machine, restart the computer, and come back to a fresh install with all my programs installed and settings configured exactly how I want them.

This would be convenient for the user, but the answer is that we can't have it because MS is worried that we would use it for piracy. Fortunately I can do this with Linux, and I can even use Linux to do this to someones Windows partition (but doing so breaks the licenses of most windows software).


Another feature linux has is called a package manager. This is a program that is built into the OS, that when you open it has a list of 20,000 freely downloadable software utilities. To install software, you just select the packages you want with a check mark and click 'install', then the downloading and installing happens automatically with absolutely no further bothering you. You don't have to click through a pointless 'installShield wizard', and you don't have to use the internet browser to go to a website and find the page to download the executable. All this is possible because the software is free.


Another problem with windows is that it is not unix. For its first 20 years, Unix was a supercomputer OS because personal computers could not handle the truly secure, multi-user, multi-tasking, behemoth back in the early eighties. I have a dual core laptop, and with linux I can run four HD 720p videos at once smoothly. You can encode video while you work and visit the web with no loss of performance. I can use the arrow keys to control a fullscreen video, and pause/fast foward etc with millisecond latency, making it easy to catch freeze frames. When I found my laptop could do this I played with it for a few minutes, since I had never felt so directly in control of any machine; a freaking stopwatch has higher latency.

I understand that you are all against me, and so it doesn't matter to you that your joke completely misunderstands the meaning of the term 'free software' in the sense of freeSoftwareFoundation.org (fsf).

The fsf does not recommend changing the meaning of the word 'free' in general, only as it applies to software. Therefore they, nor I, have any position on 'free lunches' on the basis of what I have written in this thread.

The main point is that free implies freedom, and so a lunch is only free if it comes, not only at no cost, but also with 'no strings attached.' This is why your joke fails so miserably, it is very easy to conceive of situations where lunches do not grant the eater freedom:

"Let me buy you lunch, and then you will be my slave forever."

Since we can imagine a lunch that is not free in the sense of freedom i.e. this is not a contradiction, it is wrong to say that lunch => (not free) is a tautology.

binzing said:

Ultimately the chain of reasons must come to an end, and the foundation reveals itself to be a primitive reaction.
 
  • #46
Crosson, the goals of the fsf that you keep citing are a pipe-dream. It's comparable to the philosophy of the hippie movement in the 1960's that claimed that everything not nailed down ought to be free. These are people who wanted to be given stuff without working or paying for it because of some vague "idealistic" standard that other people had to adhere to to support them. Sorry, but that is crap.

As a former software developer, I valued my time and talents, and I needed to get paid a fair wage so that I could heat my home and so my wife and I could eat and pay for gas so that we could commute to our jobs (many of my clients were 50-75+ miles away). If you wish to enslave yourself writing "free" (by your definition) software and giving it away, knock yourself out, but please realize that for individuals, software that is "free for personal use" is FREE.

I could out-extreme you and claim that you have to accept a lot of constraints (power, phone, cable, PC build, Internet connectivity standards, HTML standards, etc) in order to use your "free" software, but I won't bother. Irony is lost on the faithful.
 
  • #47
All I can add to this thread is it has got way out of hand and in turn been hijacked ...
AVG for the win :D
 
  • #48
I don't know why no one has mentioned this, but Crosson's writing has a strange quality, distant and dream-like, at once alluring yet alienating. He seems in exquisite command of the language without ever dominating it.

turbo, since you were writing code long before the computer scene took its current shape, it is probably difficult for you to appreciate the strange and unique things internet is doing to the world around us. Today it is indubitable that the free software thing works. It needs more time to oil the gears, but the fact that impossibly idealist things like it do work in practice is clear when you look at Wikipedia. The concept of Wikipedia simply cannot work, except that it does.
