I was checking some antivirus/anti-malware app to install on my rooted S4 and over and over I came across CM Security as one of the top contenders. I checked in the Play Store and that app is by Cheetah Mobile. Knowing the reputation of this company, it strikes me super odd for this app to have 4.7 stars to this application. I checked other apps by them, https://play.google.com/store/apps/developer?id=Cheetah+Mobile+(AppLock+&+AntiVirus) QuickPic is not part of this bunch but its by Cheetah Mobile 'Cloud' (https://play.google.com/store/apps/developer?id=Cheetah+Mobile+Cloud+(NYSE:CMCM)) Anyone knows what the heck is going on and can confirm my suspicion, there is something really odd going on with CM security. So what other antivirus/anti-malware you guys use. I used to use Lookout, but don't want to shell out for premium. Thanks in advance.
