Windows 7 Pro 64-bit. Runs Norton Endpoint (the enterprise version of their virus protection). It's a business machine and I'm pretty careful about how I use it.
Last night I was at the office doing nothing special on the computer when it made a sound I'd never heard it do before and I cannot for the life of me explain. It was exactly like the crunching sound that would be made from walking on a thin layer of a few inches of snow covered with a very thin layer of ice. Slow, consistent, crunching sounds.
It stopped when I muted the volume and returned when I unmuted, so it wasn't some kind of radio waves.
I would have assumed it was the Apple OS telling me I had put a few files into the trash, except it was louder, more prolonged, and gradually degraded into what became more of a general static sound -- and, oh yeah, I don't have an Apple computer!
This was truly something I had never heard before.
It disappeared upon reboot.
Any idea what that could have been?
What do you guess the odds are it's an indication of a virus? Or of anything else I should be worried about?
(The main question is whether, out of an abundance of prudence, I should restore the OS drive from an image that's about a month old. Data is on a separate drive and a lot hasn't been updated since, so it wouldn't be that much work and I wouldn't lose anything, but it sure is considerable time I can barely spare if I can avoid it.)
Thanks!
