Microtik Hijacked my computer.

Hey guys, i have never owned or used any mikrotik technologies, but just yesterday i tried to open up a browser on one of my computers and it sends me to routerOS 6 weblogin and it wont let me do anything, it only affects one computer.
Has this happened to anyone?
Im not sure if this is a virus or what but all i know is says that its Mikrotik.
if anyone can help me that would be great.
thanks.

Probably your ISP uses Mikrotik and you are seing a page hosted in a Mikrotik product due to an error. You should contact your ISP. If this computer is connected through wireless you probably connected to a Mikrotik router by mistake.
