Twice today got redirected to a url microsoftevents.com with an audio recording saying my computer has been infected and is sending all my info to hackers, and to call the 855 number listed. Happens about 2-3 minutes into reading a thread, so it's not immediate. The recording also says Microsoft is monitoring the PC and just trying to help clean my infected PC. Obviously a scam, but someone might fall for it. Been online all day with dozens of websites and only happening here, so don't think it's something on my PC.
