I've been trying to ameliorate the following infections from my system to no avail;
I've used uniblue's powersuite, spy sweeper, spybot S&D, AVG, and none have been able to cull the culprits; here's my hijack this log if anyone's willing to take a stab at this;
thanks...

I use Avira AntiVir.

It is FREE, scans much faster than AVG or McAfee, and has never allowed anything to get in my computer.

I am however, running Vista so I can't give any comparison for XP.

Good Luck!

This aways works for me in removing files of that type: Reboot to DOS. Go to the directory where the dll file is located. Type in DEL /P. This will go down the list of files in the directory and will ask you if you want to delete each one (Y/N). Type N for the good ones and Y for the bad one.
