I believe I was hit with the adobe update trojan earlier this week. I updated adobe but then mcafee said a trojan was detected and reboot. I did, nothing happened, so I rebooted in safe mode and ran Malwarebytes. I believe that caught it all, but now my internet is running slower than normal and I can't turn on my firewall or security center. The Mcafee scan is clean.
Moved this to Malware Discussion just in case. The other reason the software can malfunction is the use of registry cleaners, is that the case here?
Probably not so try running RootkitRemover, Stinger and then Malwarebytes Free - all linked in the last link in my signature below.
You should uninstall the first 2 afterwards as they can't self-update.
