SUMMARY

Chromebooks are inherently more secure than traditional laptops due to their design, which includes sandboxing and a limited application ecosystem that reduces vulnerability to malware. Users generally do not need antivirus software for Chromebooks, as the operating system is built to handle security threats effectively. However, some users recommend considering additional security measures, such as firewalls, especially for those who frequently access the internet. While antivirus software may not be necessary, the decision ultimately depends on individual usage patterns and security preferences.

PREREQUISITES
  • Understanding of Chromebook architecture and security features
  • Familiarity with sandboxing technology
  • Knowledge of common antivirus software options like AVG and Malwarebytes
  • Basic awareness of firewall functions and their importance in network security
NEXT STEPS
  • Research the built-in security features of ChromeOS
  • Explore the differences between antivirus software and firewalls
  • Learn about the implications of Single-Sign On (SSO) in Google accounts
  • Investigate free antivirus alternatives and their effectiveness for Chromebooks
USEFUL FOR

Individuals considering the use of a Chromebook, tech-savvy users evaluating security options, and anyone interested in understanding the security landscape of ChromeOS compared to traditional operating systems.

I usually use a regular laptop with Windows. I got a free Chromebook recently and have never used one before.

Thought about givign it away, but feel I could probably just use it myself for on-the-go web browsing.

Read online you don't need anti-virus for a Chromebook. The stated reason was that few viruses target Chromebooks and something about sandboxing.

Question:

Is this considered sound advice. I'm not at all computer literate on these topics. Even if "few" malware/viruses target Chromebooks, doesn't that STILL leave you open to attacks from those rare strains that do? Or, is it so rare as to make it not worth buying anti-virus? And, lastly, does sandboxing 100% protest your Chromebook from attack/malware?

Feel free to talk to me/explain things like I'm a 3rd Grader! Pretty tech illiterate!

ETA: Anyone know if a pawn shop or something like that would buy one of these for decent cash, btw?

That's what the marketing department of antivirus products want us to believe.

I like to remember deer whistles. "Put a deer whistle on the bumper of your car and you'll never collide with a deer." So if I had a deer whistle and never hit a deer, does that mean I would have hit one with no whistle?

If you touch the internet in any way shape or form, just assume you have been compromised. Better to spend a few $$ and have some piece of mind (nothing is completely fool-proof) than have personal info stolen and hacked from you.

Are you willing to pay your $ to anyone anywhere without proof that it buys you security? If yes, then I have a new invention that you may be interested in.

I can support that, but spending my money to buy something does not make me change that assumption.

Unconditional endorsement of products that cost money makes people vulnerable to scams.
 
There are good free anti-virus programs available (minor annoyance - they frequently ask you to upgrade for a fee). I use AVG. Avant is also good. Malwarebytes is also useful in addition (I have this too).

It is true that a Chromebook is more secure than many other popular alternatives. Does that mean there is zero value to an anti-virus? Probably not. Does that mean a given anti-virus is worth the money? That depends.

I'd be more worried about a firewall. I get an attack roughly every three seconds.

Anti-virus programs need special privileges to run. They might not operate at all on Chromebook. Would you have Chromebook deliberately open up OS vulnerabilities just to make it possible to run an anti-virus software?

Here's one example of the special privileges antivirus programs use. Malware could use the same thing.

Some antivirus software programs, such as Norton AntiVirus, enable a script-blocking feature, which tries to block all calls made by scripts to system objects (such as the Windows file system object) that the antivirus software deems unsafe.

If you start a script as part of post-agent processing, then this antivirus feature might cause unexpected results. If you run antivirus software with a script-blocking feature on the computer where Oracle BI Scheduler is installed, then disable the script-blocking feature to prevent the software from unexpectedly blocking agent script calls.

Actually, this brings up another question:

Can you actually download stuff on a Chromebook?

I thought they were used mainly for browsing the web, email, and using Google "office"-type products (Sheets, Docs, etc.).

I thought you couldn't download and run programs, no?

Thanks for the interesting/enlightening posts, anorlunda.

Not sure I even want to keep the Chromebook now (it was a free product I got for renewing my contract with my internet provider). :)

a.) IF I kept it AND considered anti-virus of some type, is there one you'd recommend for a Chromebook? Or, do you think it's just not needed basically?

b.) ***question for anyone*** I still have it SEALED in the packaging it came with. Do you think I could sell it at "new" price value with it still being sealed?

If it's a super pain to use and not safe, then I think I'd rather just sell it.

No, I think we said the opposite.

Yes, and that confuses me. What is the difference between an app and a software package? Do apps run in a sandbox that restricts their access to the hardware and other software?

Take Norton antivirus for example. Can it's full functionality be delivered as an app? It certainly seems that the full functionality of Norton includes interfering with the freedom of other software on that machine, or inserting itself as a man in the middle between other software and TCP/IP. Can an app do that? Could a firewall be delivered as an app? Can an OS patch be delivered as an app?

One Chromebook "show-stopper" for me is that all Google products are Single-Sign On (SSO). That is, your password for opening the Chromebook is the same as your gmail password (also Youtube, Google Play, etc.). Changing one, changes them all. I have a personal security policy of using a completely separate, hard to guess, password for my email. I suppose that I can connect to a gmail account that I really don't use, but I have not thought out all the consequences.

I'll second that. I have the same policy, and I was forced to violate that when I got a Chromebook. I really don't see why they can't fix it to allow a separate password for device unlock.

Okay, thanks for the feedback.

To be clear, you're saying you'd personally NOT use antivirus with Chromebook - nothing at all? And, someone mentioned a firewall. Is a firewall only available via anti-virus?

I don't mind that. I use Google Drive, Gmail, YouTube, etc. Same password for everything. Makes it simple.

The thing I actually think feels weird is when sites let you login with Facebook. For whatever reason, THAT feels more weird than all Google products using the same password.

I guess I cuold use the thing as a web browser at free WiFi places and NEVER log into anything with a password (bank account, email, Facebook, etc.). I could just treat it like my cell phone that I occasionally use free WiFi with at STarbucks.

What about creating a burner Google ID? I think everyone has a burner email, no? For anonymity and spam redirecting, no?

I use my Chromebook as it came from the factory. Nothing added, no apps, no changes in settings. Aside from that password complaint, it works well and I have no regrets.

Gotcha.

Sort off-topic, but would you feel the same way about Apple products. I was always told you don't need to buy anti-virus with Apple products.

The only Apple product I own is an iPad. As far as I know, there is no antivirus or firewall available for that. I have installed apps on my iPad, but not on my Chromebook.

Avast offers an iPad product, but the things it does seem pretty marginal.

Edit: My idea of the ideal secure computer is one that comes with all software in ROM, and which cannot be altered without physical access to my machine with a soldering iron. Unfortunately, security professionals say that computers that cannot get security patches are not acceptable.

Chromebook does accept updates to ChromeOS. Security pundit Stewart Baker, repeatedly skewers computer companies for refusing to admit that the OS update mechanism is a threat vector.

In the days before Windows, I had a machine from HP that came with no DOS, no Windows, no Unix, no hard disk, but it did have Microsoft Works pre-installed in ROM (word processor, spreadsheet, database). I loved that machine, and I would love to be able to buy one like it today.

Double Edit: I should also mention that after reading several reviews that say that the built-in antivirus and firewall in Windows 10 are very good, I dropped third party products. As far as I know, my Windows 10 computer has never been infected with malware.

I think you are right. In fact, I realized that I DO have a burner gmail that I use when I bring up the Chrome browser in Windows 10 and when I go to Youtube. The big difference is that I would need to make the Chromebook password something that I can remember easily so I can get into the Chromebook. I would have much better security if I activated the two-factor authentication that they advise.

Woah, really?!

I still use Avast for my Windows based computers. Haven't noticed any virus activity except ONE weird incident I posted about a few months ago.

...on firewalls...is there one built into a Chromebook already? Or, not needed?

The patches part makes sense, I think.

In the end, I am only guessing some super clever criminal with lots of time on their hands will figure out a way to even get around THAT ideal situation you list. :smile:

Kind of an interesting question, though. Can you have a computer design 100% safe?

In classified areas, the computers are disconnected from any external network. Any software or data that is brought in is processed in a long procedure of scans. All the electrical lines to phones or external networks are kept a specified distance from the computers. etc. etc.

1.) Don't trurst Mark Zuckerberg on privacy and data issues.
2.) Don't like how FB inserts itself everywhere as a login. I know Google does it too.

I trust FB less.

For those of us who worked with computers before the Internet, this sounds extremely naïve!

Any method of exchanging information with other computers, including floppy disks and thumb drives, poses an infection risk. For a recent example:

https://news.yahoo.com/revealed-how...i-stuxnet-cyber-attack-on-iran-160026018.html
An Iranian engineer recruited by the Dutch intelligence agency AIVD provided critical data that helped the U.S. developers target their code to the systems at Natanz, according to four intelligence sources. That mole then provided much-needed inside access when it came time to slip Stuxnet onto those systems using a USB flash drive.
