It started ~ a week ago. When I have Firefox browser running on the screen, if I lock the computer screen and then unlock it, Firefox launches a new Tab directing it to this website: This didn't happen before.
If I have the Firefox browser minimized so that it's at the bottom taskbar of the screen and not visible on the screen, the new tab doesn't happen and the browser works as expected.
I have Norton Security 360 antivirus running. I have run
- Kaspersky virus removal tool
None of them found anything.
Is it malware/virus? How could it have happened and Norton Security didn't flag it?
Firefox:53.0.3 (32 bit)
Windows 10 machine.
