A couple of days ago a friend, who is an older woman with very limited computer skills, get a call from someone saying her computer had been "hacked." They had her look at some stuff (what she isn't at all clear about) but it said she had 2400ish "problems". She told them she didn't have time to address the issues and hung up.
So I go over there and run Kaspersky and it comes back with nothing. In Windows Microsoft Defender said there was no AV protection but MSE is installed. I uninstalled MSE and downloaded a fresh copy and reinstalled. A quick scan revealed nothing either.
She uses this computer for email and her husband plays Solitaire. NO financial stuff at all.
Is there something else I should scan it with just to be on the safe side?
