It has been a real long time since mobile malware came into existence. But sadly, most of the users hardly follow any security measures. Heh...I should say, most of the users hardly KNOW about any security measures. Today, mobile phones are not just used for conversations but they also contain important data. And malware is a major threat for this data.
Nokia has a so called security site but one can't find it easily. Things would have been different if Nokia could give this site a little share of publicity that the N-Series phones or any other Nokia phone gets. The site has a side section with a heading: "Get Up-to-Date". However, one should not take this seriously because Commwarrior is now old news...
But still, it has provided some good security measures which a user should be aware of. Anyways, here is the link.
