I too just received a worm virus, my Norton antivirus killed it. The second of such attempts from users of genealogy sites this year. There are security flaws built into certain E-mail programs that cause these problems. Outlook express is known for that problem . Often your computer mails the virus without your knowledge using these flaws. That in combination with those who do not understand the problems caused by hackers often lead to crashed computers. McAfee anti virus is popular but that company has recently given back door access to the government who can access your files. If they can access it, so can any savvy hacker. Cable modem users are in the most danger, I had a program before I got the hub that registered 30-40 hack attempts over night. Hackers use automated programs to find receptive computers, your computer may be part of their secret network used for mischief. Whenever sending E-mail to several people, always hide the addresses in BCC (Blind Carbon Copy) so that spammers can't get more address to mail to. There are address stealing web-bots that hunt for E-Mail addresses on web sites, one attack was from the Vinton site posting. Also if you are going to forward e-mail, remove all of the extra addresses as well. Frequently newbies to E-mail will receive chain letters, jokes and hoaxes and start forwarding them to friends, don't do it..it's very annoying. A good anti virus program plus a nice inexpensive firewall is a good defense against attacks. I use a Linksys network hub to protect my computers from attack.
