over the months i have had several antiviruses including avg, windows live oncare, antivir, and recently avast. however i had avg when i accidently downloaded a virus and it did not seem to get rid of it. so i switched to windows. that didn't do it either. so i switched to antivir. that one got rid of most of the viruses becasue by then more had come. but after that it kept going off like every hour on the hour. so i switched to avast. this one seemed to do the trick. but revently it picked up another 8. i thought they were all gone because i did a complete system scan and deleted the ones it picked up. the on access scanner had finally gotten to scan windows system folders and it picked theses guys.

C:\WINDOWS\system32\wqvnpeqq.dll
C:\WINDOWS\system32\rrksfvlm.dll
C:\WINDOWS\SYSTEM32\RRKSFVLM.DLL
C:\WINDOWS\SYSTEM32\WQVNPEQQ.DLL

i dont know what they are but it says that they are viruses. please help becasue they keep showin up. thanx
