"The latest virus, called Bagle.AI by some antivirus companies and Beagle.AG by others, spreads through e-mail as an attached file, which infects a user's PC when opened. The virus is extremely similar to previous versions of the program but uses a different form of compression as a way to dodge virus defenses."
As always, TechSpot recommends that you install up to date anti-virus software on your machine, which you should regularly update. You should also kill all viruses writers on sight. No, scrap that. Instead, bury them up to their necks in doggie doo, wearing only women's underwear. Then kill them.
Meanwhile, watch out for Bagle. Its everywhere.
