I realize some of you have been getting pop-overs or autoplays or something similar, though I’ve never gotten one (and I’ve checked when not being logged in, on different browsers, etc).
Just in case it is Sitemeter doing it, I’ve change the Sitemeter setup so it doesn’t run any scripts. If anyone experiences a pop up in the next day or so, please post it here. I’ll be checking this thread periodically to see if Sitemeter was the problem.
Also, if you’re running Windows, there are thousands of malware programs that can be infesting your computer and causing pop-ups. There are dozens of anti-malware packages — here’s the official Microsoft contribution to the advancement of technology. I’m sure others will disagree (and, boy, is this is the thread for you), but I always recommend the standard Microsoft anti-malware and anti-virus software. It is unobtrusive, it updates automatically in the background, and it is pretty good (none of the computers I’ve installed it on have become infected).
