Hello... I do not even know what security concern to post this under, since it is not a pop-up and I don't know what spyware is. There is a fake MSN search engine (with a lethargic, cheap butterfly icon) that appears in the search engine sidebar to my start-up page when I first get on-line and soon, of its own free will, launches into a full-page screen that blocks out everything else, including my scrollbar. It will not let me close out of it. The only thing I can do is click on one of the search options. When I do a control-alt-delete to end the task, no separate search engine appears in the listing... only my start-up page.
Is this a parasite type site? How do I get rid of it. It is extremely frustrating and I'm sure it is making my computer vulnerable to other hits as well.
I have Norton Antivirus. Since getting and removing the sasser worm, I have downloaded all Windows and Norton updates and enabled my browser's firewall. I don't know what else to do.
Thanks for any and all help.
