Somewhat of a long story, but here it goes.
The other day I was on the internet and a window popped up
saying that some of the Windows files had been replaced,
but I figured it was just some random, annoying po-up, so
I disregarded it. A little time passed and I begun to
notice that my computer was acting very slow and after
restarting I received a pop-up from my anti-virus program
that a "VBS_FREELINK" virus was found on my computer, I
had to restart my computer a couple times, but finally I
was able to update my virus software to the point where I
would no longer get the pop-up about the virus, (so I am
assuming at this point that it was deleted) but my
computer was still moving at a speed that is much slower
than usual. Then when the computer was restarted again, I
got a pop-up telling me that a program called n-CASE was
deleted and asked if I wanted to reinstall it (I have no
idea what n-CASE is, so I didn't want to blindly have it
reinstalled) I have contacted Microsoft about the problem,
but they gave me no help except that they told me to come
here. If somebody can explain the things I previously
mentioned or has any ideas about what I can do to get my
computer back to normal it will be greatly appreciated.
Clean up the machine and secure it:
Note that Microsoft is not sending you patches in emails nor should you EVER
open attachments you did not expect in emails. You simply posted your
un-munged email address to the thousands of newsgroups that this is spread
to around the world and it has been "harvested".
Please Notice that if you use AOL, you should at least upgrade to 9.0 or
greater before doing any of the fixes. I know you can get AOL 9.0 at almost
any convenience store, gas station, super market or other retail outlet in
the world, so this should not be a problem.
Turn on that firewall...

(It has been reported that it now works with AOL 9.0+)
Make sure you have all the updates (critical) installed from:
http://windowsupdate.microsoft.com/
(Scan for updates, Review and Install)
Get rid of the spy/ad/mal-ware..
(Yes - using MORE than one of these..
I recommend at least the first three. Also..
UPDATE the definitions for them before using.)
Spybot Search and Destroy

Lavasoft AdAware

Hijack This!

I also like "The Cleaner" and "SpywareBlaster" and "SpywareGuard".

The first is a PAY product, but useable for 30 days - it has found and
eliminated problems in the past the others did not. The latter two are
prevention mechanisms. I like SpywareGuard for those with enough processor
to have something running like antivirus software - and it prevents browser
hijacking quite well. SpywareBlaster is a FANTASTIC free product, I suggest
getting this after you cleanup and keeping it updated as well....
And Assortment of Others:

ALSO - Be sure to IMMUNIZE after you clean up. SpywareBlaster and Spybot
Search and destroy both have these features - use both!
After you cleanup your PC somewhat of spy/ad/mal-ware, verify your antivirus
software is updated and run a full scan of your computer. If you have no
antivirus software - get one NOW! Grisoft AntiVirus:

Empty your Temporary Internet Files and shrink the size it stores to about
80 to 120MB (seems to be an optimal size for the normal user)
- Open ONE copy of Internet Explorer.
- Select TOOLS -> Internet Options.
- Under the General tab in the "Temporary Internet Files" section,
do the following:
- Click on "Delete Cookies" (click OK)
- Click on "Settings" and change the
"Amount of disk space to use:" to something between 80MB
and 120MB. (Betting it is MUCH larger right now.)
- Click OK.
- Click on "Delete Files" and select to
"Delete all offline contents" (the checkbox) and click
OK. (If you had a LOT, this could take 2-10 minutes or
more.)
- Once it is done, click OK, close Internet Explorer
- Re-open Internet Explorer.
Uninstall any software you do not use often/ever. (If you have something
installed but never use it, uninstall it.) If you go through Control
Panel -> Add/Remove Programs and see things you seldom if ever use, it is to
your advantage to remove it.
Also, if you are tired of Web Page Pop-Ups/Unders.. You could try the
Google Toolbar.

Stop loading applications at logon.. run MSCONFIG and look under the startup
tab for things you DON'T want to startup! Search the Internet with Google
to discover what things are safe to remove and what things may even be
malware infecting your computer.
