Blackberries Don't Get Viruses? Think Again.
My Bold caught a bug from a very malicious rootkit/malware program on my PC. The bug spreads itself via wifi network in the firmware, so you can't see what's going on.
There's a myth that these things don't get viruses. Well, mine did. It's not a lagging issue. It's not a performance issue. It blocks Anti Virus sites, when I downloaded anti virus programs they'd disappear. Further investigation showed several "hidden" files and my service books routing through servers that did NOT trace back to blackberry.
Believe me or not as you wish. But I just had to replace 2 computers and a BBerry.
