Chances are really good that you picked up a malware bug but not very likely that it came from PG on their disk or update.

All it takes to pick this kind of bug up, is for you to click on a link to a web page.

You need to run a GOOD anti-malware program immediately to rid your computer of this issue.

My wife picked one up from a search she was doing for an elementary teacher's website. It got in instantly and put her machine into a loop. Demanding that she click on a link to remove the hundreds of viruses that supposedly infected her computer. She couldn't get rid of the popup or run any other programs she needed.

It took me the better part of an hour or more to remove it. It slowed her computer down and caused all sorts of issues.

Anti-MalwareBytes is the thing I used to clean the computer. I have this program on my machine and run it periodically as normal maintenance on my machine.
