What the heck is this! Last day when I was using the internet on my mobile, then it hanged and then switched off on its own. Ever since then it is not working properly anymore. I guess that I need to build up on my mobile phone security. How can I have the mobile security when I am using the internet on it? Please tell me about some anti-virus or the anti-malware software system that has been designed for the mobile security only. Help me with this people.
