Linux is Powerfull from Virus

At a first time i using linux operating system, i feel not comfortable with this operating system, couse we usualy using a microsoft windows, begun from I still a student until i now , because our curicullum in indonesia is being doctrin with microsoft product , so if we consume other operating system we will fill not simple, at a first time i using microsoft windows as a server, but a virus was attacked our sistem, a virus like trojan horse, w32, bararontok was attacked our system, many of our data was lost and broken, fuck you virus.
The others side we got some problem to using microsoft windows, we forbident to using illegal software like piracy microsoft windows, police swipping any company for piracy product, but to use legal software company must pay a big cost, so our company switch to open source, so I and my team try learned linux.
After i using this operating system i am to be very interested. couse with this operating sistem, our sistem is protected from virus, spyware, etc so a system if very stable. Thank You LINUX.
