My brother is a sales rep. for Verizon and he has told me numerous times not to get an anti-virus app for my 2.2 Thunderbolt because he claims Androids can't get viruses and that the anti-virus apps may just brick my phone and become inoperable all together. But other reliable sources recommend them, so what is the truth about them? Should I get one? Can Androids actually become infected? And who is right in this?
