Don't Fall for Scams
Popup messages warning you about malware are scams.
Do not click to "download antispyware", do not click to "update Windows antivirus", do not call the phone number.
These are just as bogus as the phone calls claiming to be from Microsoft or your ISP. They want you to install spyware or give them your credit card number.
Hang up and ignore these.
