Recently deleted clean master. Tried to update and noticed it was removed from the app store. So I googled why is it gone. Come to find out that it was taking information from you. it was BANNED. Omg. I couldnt believe it, but glad I found out. so now I'm double checking in security master is safe. Because it's now no longer in the app store. But now, since the previous commenter,said that those cheetah apps were together. Then I guess I have to delete security master now. Be Cautious
