I just read a post on Geeks! that disusses the "SQL" computer virus. CLICK HERE to read the "Biggest Threat Today SQL Injections" post that has great details about how it works. Here is the YouTube video that goes into more detail (from the post):
Yesterday I read in the New York Times blog about the "Conficker Worm", a virus that is set to run on April 1st (no joke). They recommend making sure everyone has updated virus files, runs a full system scan and makes sure back-ups are up to date before April 1st. Those steps are good to do anyway to make sure your computers are as secure as possible, even though new threats happen regularly. Windows users should also make sure they have run the "windows update" and "security updates".
It is unfortunate , but new viruses pop up all the time (so this is not "new"). The only way to try to protect yourself is by installing internet security software, running auto scans, updates and doing regular backups. I also suggest having any personal financial information on a different computer then that used by the family – where lots of web surfing takes place. The more web surfing that takes place on a computer means that there will be a greater risk for computer virus infection.
