Internet-Address not found

I recently had a virus featuring a fake antivirus software. I had pop-ups every 30 seconds. Luckily, I was able to remove this virus with the help of Malwarebytes. However, one problem remains. It may not be connected, but it sure correlates closely to my virus problem. Ever since I "caught" this virus, may web pages showed the result "Address Not Found". This was especially true for any antivirus software sites. (I downloaded Malewarebytes onto a flash drive from another computer to get it onto my comp. How can I remove whatever is blocking me from certain web pages?
