Virus infects my computer at random times?

[xEmilyx]

I'd say about once a month I get a random notification that my virus protection thing has blocked a Trojan virus. Its alright, I guess, because it removes it, but how come it gets me at random times? I mean Im just on facebook or writing an essay and it pops up, Im not downloading anything or clicking on strange websites. Is there a way I can remove the virus completely? Do you think its infected my computer?

Oh, you expect a virus to be on a particular schedule huh?

Its probably a worm virus and is still on your computer your virus protection is detecting some of its activity but can't get it all so it will slowly get worse its like cutting the weeds off the top but leaving everything else

If I were you I would backup my data and reformat my hard drive before it crashes the whole thing (because it will)

Download and install http://www.malwarebytes.org/ .
Update it, then run a full scan.
Once the scan is finished, remove found items.

PS: Your antivirus seems to have problems removing viruses, try http://www.microsoft.com/security_essentials

I am not going to keep repeating myself but please ... do NOT listen to these spams of "Reformat" that (the bots) post that as an answer on every single YA thread... it IS NEEDED at times, but not in this case.

The issue you have is that although your AV is removing part of the infection, your not completely removing all of the infection.

I would suggest Avast, Avira, Eset's NOD32, or even Kaspersky as an antivirus but I do not know which one you currently have.

I would get one (or even both WHICH ARE BOTH SAFE to install alongside your AV... I have both and Avira on one of my PC's .. and both and Avast on the other... (I just like Avast and Avira) )

MalwareBytes ( http://www.malwarebytes.org/ )
And
Super AntiSpyware ( http://www.superantispyware.com/ )

I have seen people have tons of malware removed by these two great programs, and their AV says they are 100% clean

Good Luck,

People who tell you to use system restore to remove a virus don't know what they are talking about.
A well written virus will infect system restore, so turn it OFF before following my directions so the virus can't resurrect itself. After malware is removed you can turn system restore back on.


Many forms of malware are able to remove the executable part of antivirus and anti malware programs WHILE you are downloading them, so my suggestion is this.
What you should do is use a second computer to download a copy of malwarebytes and then update it. Next, copy the updated malwarebytes to a CD or DVD(if your pc can read DVDs) and insert the CD or DVD into the drive.TURN OFF your infected pc, not restart, TURN OFF.Wait 2 minutes then hit the power button while continuously tapping the F8 key. You want to enter safe mode (WITHOUT networking) and run the malwarebytes from there.

If you have problems doing this, register at forums.techguy.org/
They will walk you through it.

I would also suggest that you install some kind of antivirus, there are many free ones. I have used !avast quite successfully for well over a year, and it's FREE
