It seems my desktop has acquired the malware/virus problem that's been going around lately, wherein Avast regularly blocks spontaneous attempts to visit malicious websites such as anythicago.com and alwaysisobar.com. I've also noticed that my desktop has been much slower than usual to load websites since the Avast popups regarding these blocks started appearing. Neither Avast nor Malwarebytes has been apparently able to detect or remove whatever this thing is so far, and I'd greatly appreciate some help in rooting it out of my computer.
I've attached my most recent Malwarebytes scan log to this message, as well as the Farbar FRST and Additions text files, as outlined in the malware cleaning sticky thread.
