Hi, I was wondering if anyone could help with this little situation I've got myself into!
A pc running XP Home which I've been working on has a StartPage trojan infection which is cleaned by Norton antivirus upon scanning but replicates itself on reboot.
Earlier today I scanned the pc with the eTrust antivirus web scanner which detected the following infected files;


None of these files could be cured and in my overzealousness I chose to delete them.
The following files could not be deleted;


Now when I boot the pc and login, the explorer.exe process does not run and can't be found when I try to start it manually, resulting in a pretty desktop wallpaper but no icons, start button or system tray.

When I look in the windows folder using the cmd prompt, explorer.exe appears to still be there.

Do I have any choice other than a windows reinstall?

Thanks in advance for any help/suggestions

Do a sfc /scannow

Click start then run and type: sfc /scannow

That will start the windows system file checker which will go through your system files and repair/replace system files that are missing or corrupt.

you will need your windows disk to do this...

Hi windowsxp550 and thanks for your reply.

I tried a SFC/scannow earlier in the day but to no avail, it doesn't detect any problems.

Thanks for the advice. I did pretty much get to the same end result once I had worked out it was those darn iexplorer_dbg and explorer32dbg files which were causing the problem.
A really good piece of advice for anyone reading this post who may be suffering the woes of malware;

If you're not 100% sure what you're doing, post a HijackThis log and let the experts have a look, it may save you a lot of time and heartache!
