The more I think about it, the more I think you are still infected. What I suggest is the following:
1) Perform a clean install of Windows XP after using KILLDISK. It may not be enough to only format. Some infections can survive a simple formatting. (more detailed instructions below)
2) Fully update your instance of Windows by going to Start > All Programs > Windows Update (near the top of the list). Keep going back until you have installed all updates available.
3) Only install software from trusted sources, not free software (with the possible exception of AVG antivirus). Install MS software, but NEVER P2P software like Limewire, Kazaa, Bearshare, etc.
4) do NOT reinstall your data. It may contain a virus.
Use the computer for a while after doing these things and see if everything works out ok.
and a HJT log shows nothing suspicious,
Who helped you determine that? You should never attempt to fix anything using HijackThis, until someone who is experienced at reading the log outputs, has a chance to review it. Fixing the wrong items can make a computer unbootable.
Spaces, extra characters, spelling, file location, plus numerous other subtle changes, all make the difference between a good, or bad, file entry.
HijackThis is an ennumerator. It lists what is found in certain areas of the registry, or system files, in an easily accessible manner, so that those familiar with the use and reading of HijackThis logs, and windows programs, can determine what is infecting the machine, and how to remove it.
It is not a removal tool. It will indeed remove the entries listed, but that does not cure the underlying problem. The problem must be properly identified first, and cured, prior to removing the entries with HJT.
Otherwise you leave the infection, and remove the keys which are needed to identify and remove it .
Removing entries in HJT before the problem is properly identified, and correct removal instructions posted, can make the problem undetectable to other detection and removal tools. Hijack this should only be used to clean up the entries left behind, after you have properly removed the offending program, file, trojan, worm, hijacker etc. And this usually requires help.
You can run Killdisk to delete everything including any infections. This is a free progam and can be downloaded HERE
. Put the program on a floppy disk or a CD.
Then run a DOS disk, such as a Windows 98 start up disk, when the computer boots to DOS, type "C:" (without the quotes), push ENTER. Then type "fdisk" (without the quotes), push ENTER, then just push ENTER at each selection that you are prompted to make (in other words, just accept all defaults). You can download what you need HERE
Then reboot with your XP CD in the cd drive and reinstall Windows, being sure to choose "Full Format" instead of quick format when prompted.
Be careful about reinstalling your data as it may contain a virus or other malware.
