I do not use any real time antivirus, I only scan my pc with MBAM and superantispyware.
“I do not use any real time antivirus, I only scan my pc with MBAM and superantispyware”That is not a very good idea. You can check your Add-ons in your browsers to see if there are any add-ons that could be causing that problem. I will cease help you with this problem until you install and activate one of these AV programs. I recommend MicroSoft Security Essentials.
