I'm working on a friend's machine, and this little bugger has me stumped.
It comes and goes, with no real recognizable pattern. Just a plain stripped down (no toolbars, menu options, etc) instance of Internet Explorer opens up with some advertisement in it. Insurance, registry checking software, viagra, bogus system warnings, even an image that looks like something ran at a command prompt. I've read the faq, and I have run up-to-date AdAware and Spybot S&D apps. I also did an online virus scan from Trend Micro and it found viruses it couldn't clean, but I removed them to an archive on another machine, ran another scan and it came back clean.
Oh, and when I looked at the properties of one of the ads, the domain is z1.adserver.com. I googled that but found no solutions.
Here is my hijackthis log file.
