Why always get virus - Nokia N72 Cellular Phone

First of, your question is a tricky question.
There are many anti-virus programmes on the net. Free and pay. Things to keep in mind is virus come first than the anti-virus comes out. Virus programmers are always looking for weakness in a system and they write a virus for many purposes. Other annoying facts is even if the virus was killed or out of the programme, it is very hard to fix anything they have damaged. So, you have to keep in mind even though you successfully killed a virus you still need to fix damage it has cause. That is why IT people always recommend to back up your data, format your HDD and reinstall windows and the programmes you are using.
Said that, now let's get to the virus problem.
Free anti-viruses:
1. AVG
2. AVAST
3. Avira
4. McFee

Others
1. Norton
2. Microsoft - ForeFront, Security Essential (comes with Windows license version.)
3. Kespersky

The above anti-viruses are good in their own ways. As said before you need fixes, patches to fix the damage. They also have fixes once the virus has been identified. Check out their websites by google searching.

Good luck mate.

Hmm, here's a solution: Uninstall Avira and point your browser to this website
