Virus problem on friend's machine.

[Priapus]

Howzit all.

My friend has brought his PC to me to see if I can clear the virus on it. Now, he has no anti virus software or anti spyware software on this machine for some reason. So, I inserted my tools CD which contains the anti virus software/spyware. However when even I try open the folder containing the software, the virus closes the folder. So I ran a command to run the .exe files from location. Again, virus just shuts the instlation down.

I then opened up task manager to see what was running, again, virus shuts it down. So, I open up HiJackThis, won't run due tomissing .DLL files and won't let me reinstall it.

I then rebooted the machine into safe mode, and try the above - same things happen again.

So, other then formatting it, how do I clear this nasty virus?

Thanks for any help guys!

its probably due to a rootkit which is very hard to remove because they basically have 100% charge over the system when they get in, and they block anti virus programs etc from running. avg anti rootkit calls itself random names to protect itself from being auto-closed by rootkits but you probably wont be able to install it. id just reformat.
