Once in a while during browsing, multiple tabs will open unexpectedly in IE7 on the same page. This is not the same page every time. The computer gets overwhelmed with so many tabs open and the only way to fix it is End Task in Windows Task Manager.

I have run multiple virus scans with several different scanning utilities. I have also run multiple different spyware, adware, and malware scans such as Spybot and ad-aware. Nothing seems to be too out of the ordinary and I'm convinced the computer has no virus.

Has anybody see this problem? and does anybody have the solution to getting rid of it?

(I'd prefer not to switch to Firefox if at all possible.)

Thank you in advance.
