Good question.

I tried to get him to do just that, but he said that nothing happened when he clicked Change/Remove. It may have been him as he is very nonPC. I will be having a phone session with him this morning. Just enough time for me to get Avast and see what it looks like.

No other AV software from what I can recall.

And as I said it appears that whatever happened is preventing him from accessing the Internet.

Cheers
