LOL, I don't take any chances now. I run a firewall, an up-to-date virus scanner, as well as connect through a router. It seems that both my OS are extremely vulnerable to being on the net and are virus magnets. I found out that adware can cause your computer to behave as though it has a virus. Last year my ISP cut off my email ability because apparently my computer was sending out hundreds of emails without my knowing about it. I did a virus scan with my eTrust Anti Virus scanner, and did an online one through my ISP and one through another site. I also did an online Trojan scan, and all of that showed my computer clean. I next downloaded the newest versions of Spybot and Adware and got new signatures for those and found almost 300 spyware files on my one computer. After I reported back my findings, they gave me back email ability and had no further problems. I'm extremely cautious about emails. I NEVER open email attachments from anyone, even friends, without first saving it to my hard drive and scanning it. I also don't preview my emails in Outlook. So it's a good idea to use tried and proven anti-spyware programs. I have a Dell and in one of their notices to me provided a link to yet another spyware scanner. I did the online one and found that it picked out files from 5 of my graphic applications. Had I deleted them my programs would have been nonfunctional. So all spyware programs are not built the same.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
