Sorry to add hassle Arthur! McAffee has just picked up a potentially malicious threat from your Chat Room. I am cleaning my PC and installing McAffee WebSafe. Could be their sales pitch of course but I know you have had hacking lately.
I use AVG Free now, indeed all my family use it, none of us have had any problems. Son-in-law works at the very top end of CGI, he uses AVG too. Apparently McAffee allegedly slows computers down by up to 10%. I did have it, glad to see the back of it for various reasons.
