Persistent malware

[Spindrift]

Hello:

I'm new here, not at all tech savy, so please bear with me. I've been using the free version of MBAM on my notebook computer (Compaq Presario with Windows XP) for a while now and have been quite impressed with how well it works. I was planning on purchasing the the full-function version this month, but now I have a concern about a problem that popped up last night.

On a quick scan, MBAM found some infected objects, then indicated quarantined and deleted successfully, and would delete the rest on reboot. After reboot, I started surfing the Web and got a lot of extremely annoying redirecting to various Websites. I ran another quick scan, and the same objects were still infected. Went through the removal process several more times, and the objects remained infected. I could really use some help here.

Thanks in advance.

This one is tough as it breaks a few things intentionally . If you kill off all instances of rundll first and then run a scan it will be removed .

One note though , anything running BEFORE you kill rundll will crash , this is an intentional counter and why you need to run MBAM AFTER you kill rundll .

Thanks for the replies, and sorry for posting in the wrong forum.

Today, when I got home from the office, I ran a few updates and quick scans, and now nothing malicious was found. Go figure?
