Hello! Earlier today I was infected by the Antivirus Action malware. Following instructions I found on this site, I downloaded Malwarebytes and ran a full scan in Safe Mode. The first time it found and removed several infections. I ran it a second time and it found nothing. My system is greatly improved, but for some reason my Microsoft Security Essentials suite is switched off and I cannot get it to restart. In regular mode it is non-responsive, and even in Safe Mode I cannot switch it back on for monitoring (even though it will scan). I'm concerned that there may still be traces of the infection in my system. Can someone please help? Thank you in advance.
