One of the areas where Linux really shines is security: you do not really need an antivirus if you are running Linux as an end user. In the Windows world however a good antivirus is almost a requirement as viruses and malwares are commonplace. I have personally seen Windows computers being infected less than an hour after being connected to the internet.

Several security firms are warning against a Beselo worm that targets Nokia 6630, 7610, 6680, and N70 smartphone models. A new mobile virus, referred to as the Beselo worm, has several security firms concerned about Nokia (NYSE: NOK) smartphones getting infected. One such firm, SMobile Systems, said it has issued a disinfection tool to contain the virus.
F-Secure, an anti-virus and intrusion prevention provider, first posted an alert regarding the virus in its blog last week. The virus is said to affect smartphones running the Symbian S60 Second Edition operating system.
