Hello. I got this update today, and now Task Manager shows that "RegSvr.exe" is running constantly. I looked it up on Google and people say that this is a virus that's a key/mouselogger and messes with other programs. Scanned it with MalwareBytes, Avast and Security Task Manager (wich calls it "Avast Antivirus installer"), and they all say that it's harmless, though I'm not sure because it doesn't let me close it with Task Manager and that's kinda suspicious.
Could someone tell me if it's safe or not? I'm pretty sure this program wasn't on my computer prior to this update. Also, I'm using Windows XP SP3 by the way.
