Hi: my advice to you always use Kaspersky for your Internet protection...
as with regards to personal antivirus
You have virus or ad-aware on your computer that is why you are getting those pop ups shutdown computer boot up in safe mode with networking and start your real anti virus protection and do a scan look for anything in your add remove programs folder to see if you see that name in there. While in safe mode networking you can search the Internet with out this problem happening but i recommend removing the virus/ad-aware
