is incorrect approach to security issues.
I disagree that the firewall is the most important part of computer protection. Instead of downloading sp-2 (why not sp-3, by the way) we recommended that he download Avast, which takes about 5 minutes and then connect to the internet to download Windows and AVAST updates.
When the computer doesn't have any protection, the most important thing, and the only thing you need at the moment to securely connect to the internet is a firewall. Antivirus can be safely downloaded, when the computer is already connected to the net.
Then, I can't see how it's possible to offend anyone just by simply disagreeing with someone's opinion.
In any case, if someone feels offended by any of my posts, I apologize.
I hate cold showers, though...
