I am a frequent user of this forum and I told her I will submit this for my guys lol and gals. You have always served me well. This started as a maware issue so she had it removed reinstalled firefox then brought it back. She is a employee of mine and her bell via firefox stopped working so for now has been using Chrome. Anyways she went back to Firefox today and a popup appeared saying its from Microsoft that she has a virus all very suspicious to me

Any ideas for her?

Thanks and this is Natalie :)

It's possible that she is seeing a fake antivirus notification, which isin itself a virus, or an attempt to get you to install a virus or give a random group her information.

Please download and install malwarebytes (www.malwarebytes.com) and run a full scan, removing anything it finds. Then, update Windows entirely, and then run a scan with Windows Defender.

Let us know if this helps!
