I need help getting rid of a really nasty trojan on my neighbor's computer. She is running Windows XP Home Edition on a Dell 32-bit desktop. She is seeing the following symptoms: a) very slow operation, b) all of her antivirus software is shut down, c) constant redirects, when surfing on Google. I have tried to use system restore, but it won't work, no matter how far back in time I go. I have tried installing a brand new Kaspersky security suite disk, but it shuts down about 1/3 of the way through the installation process. I have tried running SUPERantispyware, Malwarebytes, and AVG (all in safe mode), but none of them can see it. The only program that recognized it was Kaspersky's Virus Removal Tool, which I downloaded from the internet onto a thumb drive from my own computer, which I then brought over to her computer and ran in safe mode. It identified the trojan as a "afd.sys" trojan. I followed their instruction, but was told that I could not delete it. I was then offered the choice of quarantining it, which seemed to work, as I was able to then surf the net on Google without being redirected, but then, upon rebooting, it was back again. Is there any way to get rid of this thing? Any help would be greatly appreciated.
