ok so i'm working on a friends computer running XP.
their explorer.exe file was infected by a worm and they accidentally deleted it instead of cleaning it.
luckily the file was in back-up, so they pulled it back out, ran a system restore, and after virus and spyware scans and what not (Kaspersky and Ad-aware if it matters) they came up with no new problems and explorer was running again like normal.
The only remaining problem is that some of the system functions are no longer working like Backup and System Restore, and every time you try to run them, an error runs that says something like the task mananger can't read the image file and it lists the name of a couple dll's ( i can get the exact targets and errors the next time i'm over there).
Chances are you probably can't help until i get those errors, but i thought what the heck, you never know.
Since these mainly seem like system problems, and i can't find for the life of me the name of the worm that infected explorer, nor do i know the extent of it's damage, should i reinstall windows for them? just wondering, cuz this isn't really my field (as if you couldn't tell).
i can get pretty much any information necessary, and there's no real hurry.
thanks in advanced, happy holidays
