Hi Ralph.
Just a bit of clarification here.
Zone Alarm is a Firewall program - not an anti-virus program.
Microsoft scans each document on their hotmail servers before it gets to yours - so you don't have mcafee on your computer.
If you don't have any sort of anti-virus program, please download AVG Free 7.5 from
AVG Anti Virus: HOME
It's a free - really good - anti virus program.
