As I am Android user, I found that my phone has slowed down in performance.
I bought and installed it on my Samsung smart phone, noticed that it is not proper anti virus.
I found that they offer very useless things like download movies n songs and blocking contacts using our syska gadget secure.
I found that after scanning they show the result of successfully scanned and 0 virus found but my phone was virus infected it is not upto the mark I didnt like this antivirus it is not useful as other antiviruses.
