Okay, so after maybe 30 minutes or so on my laptop I get a popup that says "at.exe - application error / The application failed to initialize properly (0xc0000142). Click on OK to terminate the application." Clicking the OK button at the bottom of the window does nothing, the pop-up just reappears immediately and stays put until I shut down the computer.
So far I've run Spybot S&D and rKill / MBAM scans until all results have come up clean; likewise with Kapersky's Wise Registry Cleaner and TDSSKiller.

Let me know if I'm missing any info that you need. Thanks in advance for your help and patience!
