The scan feature of this Bitdefender Anti-virus product seems to be working. There is actually a green progress meter. But I'm giving 3 stars to the company due to a couple issues. First, because the "superior" product, the Bitdefender Mobile Security, didn't do anything when I hit the the "start scan" button. Not superior. The Mobile Security version also still seemed to keep popping up the "start scan" notice. Second, the Anti-virus version didn't have a scan history feature.

Today it started showing up on my status bar & I couldn't get rid of it from there. I looked for it in my Apps & it didn't show there. It may be good, but it's strange behavior leads me to uninstall it. Any app on my phone needs to show up in Apps AND have settings options which include to not ALWAYS be in the status bar. I see response but I've already uninstalled so can't help.

Recently started using the free version of Bitdefender Antivirus. So far, I haven't had any alerts notifications as I have experienced in the past. Lately, noticing some slowing and glitching of my device, which most times are tell-tale signs of system manipulations, not always though. Note, testing is on older device. Allowing free version the timeframe needed before developing a final opinion for any need for the more advanced (paid) version, and considerably higher level of protection.
