Some of my users about 5 of 50 have ben reporting that when opening google.com and making a search multiple instances are opened untill it is stopped. We are using Nod32 Business edition and it is not finding anything. This sure sounds like some kind of virus but i have searched and not come across anything that can explain this.
Now other users have started to get a robot warning window and need to type in a captcha.
I appriciate any help i can get.
