What are the symptoms of virus Infected Computer?

We can't clearly list down the symptoms by saying these are the symptoms of virus infection but most of the viruses have same kind of basic symptoms (Note : Only Basic) but they will have difference in their functionality.

The following symptoms are listed in http://www.kaspersky.com/symptoms website but they are only basic because everyday, antivirus companies face new virus infections alerts which have their unique and new functionality. Until the operating system find and solves all the problems (unknown), the operating systems will be the medium for the virus infection and all the security threats.

Would you like to use Open Source Operating system because of the fear about Security Threats?

Please don't be fool.

Are you an Open Source Operating System User?

Are you laughing, by thinking that your computer will not infect with computer viruses, and you are always safe from these threats!!!

No, way!!. You are also still in trouble!!! 

Do you know that, your Open Source operating system also has an internal antivirus?

Why most of the antivirus companies are releasing their antivirus for open source operating system, if there is not virus invented for open source operating system.

E.g: http://www.avast.com/linux-home-edition
