I seemed to have picked up a virus while searching this morning. Suddenly, Antivirus Security Pro popped up and told me I had 22 threats and I should buy their program to help myself. I already have an active account with McFee Security so I didn't really believe the pop up. However, I am not able to view pages in IE for more an a second before the page reverts to a a page asking if I want to activate Antivirus Security Pro (recommended) or Ignore (not recommended). When I choose Ignore, it displays the page for 1-2 secs and reverts back to the page encouraging me to buy the software. If I click the back arrow it takes me to advertisements and not the previous page.
I ran a full machine scan using the McFee software and it returned 1 issue found and removed, yet the issue persists.
On a "clean" computer, I did research which suggested I run Windows Defender Offiline. I did that by saving it to a USB drive and trying to run it on the "infected" machine, but the "infected" machine won't let it run. There was advice to change the name of the file, but that didn't seem to make a difference. I have now tried this with Malwarebytes and rkill and can't get any of them to run from the USB drive or a shortcut on the desktop.
I don't know what else to try. Does anyone have any other ideas? Any help would be greatly appreciated!
