How do I scan my Nokia E71 phone for viruses ? They always charged me like 250.00. I am using Avira on my PC ?

Who is charging Rs. 250 for scanning for virus in your phone ? Their are many antivirus now available for symbian. But in my person view they are not very effective, best way is to take precautions. They are the best solution ie. precautions. .. like.
-> Never use memory card of other people until you get it scanned in a computer which is also not infected.
->Never install applications from untrusted sources.

etc...
