hmm...u can go 4 f-secure antivirus(search google)...but that was not of any use to me bcuz even with fsecure n few other antiviruses my cell got infected by the carib(a.k.a caribe cabir etc) virus n antivirus din give any warnin...my cells battery got permanently screwed cuz of its massive bluetooth action n i had to replace it...i guess no free mobile antivirus is fully functional against viruses now...n secondly if u live in india there is not much threat of viruses spread by bluetooth(i got it in a movie hall on 31st dec 12:00 i.e new year celeb time )..but then u cn get viruses easily if u have mms activated..sms also has few but it can be cured by deleting the messages..jus check out yahoo groups(groups.yahoo.com) if u wanna know more abt mobile viruses
