Last night my laptop restarted out of nowhere while I was browsing the internet. When it finished and I logged back on, the audio from 3 or 4 video ads began playing, even though no browser was open. I looked at the audio mixer and found that the sound was coming from something called "winrscmde.exe". I muted it, but other copies began showing up in the mixer and playing other ads with no discernible pattern. I checked the Task Manager to try to kill it, but there was no application or process with that name. I use McAfee Antivirus and had it run a full scan, but it found nothing, and I also searched my hard drive for winrscmde.exe and found nothing. My laptop has done the same thing of rebooting unexpectedly in the past, nearly since I got it around 2 months ago, so it's possible the problem dates back farther than last night, but this is the first time any obviously malicious symptoms had appeared (until now I had assumed the restarts were nothing of concern). So far nothing worse than the audio has occurred, but I want to get rid of this before it gets any worse. My computer runs Windows 7 64-bit. It's an Acer Apsire 5750G-6653, if that helps. Prework logs are attached below.
