Most people don't. Conventional wisdom by bloggers and threads is that they are scams, gimmicks, and cause headaches with false positives. It is not that you can't get malware, nor should you ever be lulled into a false sense of security, but I think among seasoned android users less than 3 percent use anti virus virus apps. (Just a guess). Just don't click on anything unknown and stick to known apps from reputable sites and never be the first to try an app.
This is interesting. I believe all the apps on Google Play a pre-screened for malware, so it should be ok if the source of apps are credible. On the other hand, I'm wondering if browsing can induce malware.
I guess yes, and you may want to try this free one: Advanced Mobile CareIf so, what would you recommend?
Thanks.
