This is the second time in 3 months that my computer is infected with a virus/malware....I can't believe it!
I am using WINDOWS XP Home Edition Version 2002, Service Pack 3. The anti-virus program I use is AVG Free Edition 8.0.175.
A couple days ago as I was running a routine full scan AVG found a trojan horse named "Trojan horse Downloader.Generic8.COX" inside the file path "C:\WINDOWS\System32\Tools\Regexe.exe" and moved the file to the Virus Vault.
I did a search on Google and did not return any useful result on that filename nor that trojan horse type. I supposed that was a useless file and deleted it from the Virus Vault.
I subsequently scanned my computer again with AVG, Malwarebytes' Anti-Malware, Windows Defender, Spybot Search and Destroy, Lavasoft Adaware, and 2 online scanners (BitDefender and TrendMicro) and found no virus (All scanners are up-to-date in definitions). I even used McAfee AVERT Stinger and found nothing.
The problem is I know many trojan horses created additional copies in your computer and hid those files once they landed in your system, and certain things (such as registry and other file system/settings) might be altered to compensate my computer's security. I am wondering if what I did--deleting that infected file--is enough to keep my computer clean or I have to do some more to make sure my computer is safe and secure.
Please could anyone enlighten me on this? Thanks a lot!
