After years of being virus-free, I've finally been blindsided, and I can't get up.
I'm running Windows XP Home Edition, with Norton Antivirus 2006. A couple of days ago, I was drinking and web surfing (stupid, I know), and must've come across a less-than-friendly website.
Every time I boot up, Norton lets me know that it's found/removed duntek, then vundo a few minutes later. Each time, I've noticed that the .dll file that's being deleted has a random name composed of eight letters followed by ".dll". The frustrating part is, I reboot (as advised by Norton after it gets rid of vundoo), and the cycle repeats. If I open my web browser, it seems to trigger some sort of "rebirth" for the troublemakers. I also get warnings about WinFixer as well as randomly-appearing internet explorer windows that go to various websites for swingers, immigration stuff, and fake drive cleaner utilities.
I've gone straight to the Norton website, and downloaded their vundo remover utility, but it doesn't permanently remove the virus. I've tried following the instructions at their site, but when they say to delete:
from the registry, there's literally HUNDREDS of items under that folder that look random. Fortunately I made a backup of the registry before trying to delete several dozen. Definitely NOT the correct solution.
I've also tried fixvundo.exe and vundofix.exe, recommended by various websites (I see other users with similar problems, but the solutions seem very tailor-made). Still no joy.
I've downloaded combofix.exe, but while it was running, Norton popped up a window saying it had just deleted something, and that seemed to crash combofix but good.
I've also downloaded hijackthis_sfx.exe, but haven't tried it yet. Once I get a reply to this message about what to do, I'm sure you'll ask me to run the program and post the log file here. Just let me know where I should post it, I guess.
It looks like you folks are very patient and persistent, from what I've seen of other people's threads. I hope I don't waste too much of your time.
Thanks for your kind attention.
