My pc got a load of viruses recently. I did a boot time scan with avast and it showed, among others, 3 viruses on kernel32.dll, winsock.dll and winsock.dll. Avast could not repair them so i sent then to the virus chest. But as you know they are os files and i now get an message saying "i.explore has encountered a problem." (I'm sure that this is in direct relation to winsock.dll file going into quarantine.) The full list of viruses Avast scanned and sent to the virus chest: dmari.exe huunklac.exe kernel32.dll pnqgj.exe TMP98.tmp uxsnish.exe wmsock.dll wnwsock.dll yddb.exe i also scanned my pc with Super AntiSpyware in safe mode. It found and quarantined: rootkit.SENEKA trace. Adware.tracking.Cookie Trojan.Dropper-Cogad Trojan.Fake-Alert/Trace. How do i fix my OP system files now? Thanks in Advance!
