[Zunnurain Arslan]

how we can protect our PC from the virus of internet?
and to protect from hacking.

Properly install and configure a firewall and anti-virus software will take care of this for you.

It's a war. Malware writers vs anti malware writers. On any given day one or the other might be slightly ahead. The real answer is there is no guarantee. There are many things to do to minimize the possibilities but you can still get nailed. Sorry.

ram1009 is technically correct. One can only minimize the likelihood of Internet-born threats, you never completely eliminate all threats.

Proper firewall and network security, strong wireless encryption, complex passwords, installed and updated anti-virus/security apps, and not visiting malicious sites can go a long way to minimizing threats.

For Zunnurain Arslan, what specifically are you concerned about? Your original post really covers a broad area.
