"How do you do a screenshot?"
Screenshot key, top right of your key board...probably says something like "print screen" on it.
"how do I check for correct spellings of actual files vs. viruses?"
Often times, you can't. And actually, if you have an excessive number of svchost.exe's running, you're probably being used...nothing too much to worry about unless you have random uploading/downloading.
As far as viruses go...
Be very careful...and honestly, if a virus is only one file, it'll probably just be idling there anyway...I have five "viruses" on my computer, though they really aren't. Probably some cheap trojan or dumb file...then again I don't keep anything personal on here so nothing to worry about.

But there's not too much to be afraid of if the virus program says it's a baddy, just manually go in and delete the sucker.
"where can I find 'registry mechanic'?"
Honestly I wouldn't worry about these, they always make me uneasy. I prefer to edit registry myself, and only if I must.
"what is DL??"
In this case, "down-low", means keep it secret. However, it's also often used as a short cut way of saying download.
"and what is p2p stuff?"
I know that as pay-to-play for games, or it can be used as peer-to-peer as in file sharing.
And coming from a guy who has experienced all spyware imaginable, I've always been able to get rid of it. A combo of ad-aware, spybot, hijack this, and a little use of my own noodle, nothing can stand up to me. :)
As a note, DON'T CLICK ANY OF THE LINKS THAT ARE BELOW, THEY ARE MERELY THERE TO SHOW YOU NAMES OF THE FILES TO DELETE. OTHERWISE YOU'RE POSSIBLY IN FOR SOME NASTY SPYWARE. *caps off*
Since I'm here, I"ll post my little spyware removal steps:
In Windows Explorer, make sure that the option to "show all files and folders, including hidden and system" is turned on. Open a my computer window, then go to "tools, folder options, view"...then look under that list.
Update all of your spyware removal programs.
Reboot in safe mode. Some computers do F8 or F11, differs. The only sure way is to go to run, type in msconfig, then under "boot.ini" click "safeboot". To come back out of this, just do the same thing except click normalboot.
Empty the "Temp" folder:
C:\Documents and Settings\{user}\Local Settings\Temp (some computers can't take deleting them all at once if you've let them build up too much, in this case, delete portions at a time)
Delete all cookies (Don't really have to...but may as well be safe)
Run hijackthis (search google for it, handy thing) with nothing open except for it alone. If you'd like, and I recommend it, allow it to create a restore point. You shouldn't have to use it, but if you screw up it's good to have a backup.

C:\Program Files\Web Offer
C:\Program Files\Windows ControlAd

Next, run adaware with in-depth scan, full scan.
Then spybot: search and destroy, and then click immunize after running that scan.
Just go back to msconfig as before, mentioned up there, and you'll reboot to a nice shiny computer. :)
