Even if you don't use Internet Explorer, McAfee SecurityCenter does, it is an IE page in fact. So could you tell me what operating system and service pack this is and what version of Internet Explorer is installed (Help/About) please?
The fact that you stated you don't use it makes me suspect that you haven't accepted any updates to it either from Windows Update which could leave you open to infection.
My Operating System is Windows 7.
I update my computer frequently and there's no available update, im not sure what service pack I have, and apparently I have Internet Explorer 9 which I didn't know till 5 seconds ago...
Right-click Computer on your desktop or in your Start Menu and select Properties. That will tell you if it's SP1 or not.
Open IE9 (if your system is 64-bit open the 32-bit IE, both are listed in the Start/All Programs menu) and go to Help/About and make sure it's not saying beta or anything other than plain old Internet Explorer 9.
Go to Tools/Internet Options/Advanced and click Reset > Apply and OK any prompts.
Close and reopen IE and go to Tools/Manage Add-ons and re-enable any you might need.
See if that improves things.
If not contact Technical Support either by phone or online chat, both are free and linked under Useful Links at the top of this page.
It says Service Pack 1 and it didn't work...
Then I think the best bet is to contact Technical Support and have them look at it, tell them you already tried resetting IE9. This one is very puzzling because it seems to hit people at random. We only used to see it when people had beta versions of Internet Explorer installed and started with IE7 beta, but now we seem to get it happening when it isn't supposed to.
There are some steps you could try before going to Tech. Support....sorry I just realised that these may work....
