suspicious .htm downloads
I've been seeing suspicious .htm files appear in "downloads" when I hadn't requested any downloads. When I try to open the file, it always appears blank. Once I rebooted without deleting the file, and my system acted like it had a virus. I rebooted in Safe Mode and reverted to a restore point, then everything was fine. But I'm still seeing those suspicious files appearing, at least once per day. How do I stop them?
