When i'm browsing the internet and click on certain links, a new IE window opens with "Action Cancelled" in it, then another, and another etc down the screen. I left it once and it loaded over 50 separate windows and would have probably continued. I also notice that iexplore.exe was swallowing all CPU usage. I tried closing the group (I have windows XP pro) but more just kept opening. The only way i've found to stop them from opening is to open task manager and shutdown iexplore.exe. I don't believe there's a pattern to the links as other users of my PC have experienced it on different sites. Could this be a virus? Can anyone help?
