Hi all,I am having serious issues in my Ubuntu 12.04 machine.When i am trying to login to my user,the keyboard doesn't work.I have to use on-screen keyboard for that and later on after logging when i try to browse files the whole PC is stuck up and suddenly some file(A file in the ubuntu installed drive) on my hard drive opens up.yesterday i got a warning like "Someone might be Eavesdropping on your session.Unable to grab your mouse".Is my PC really getting hacked

God,i have thought that Linux environment is less prone to these things and see what now..I am under the pressure of hacking my PC!!

Someone,pls suggest me and what's going wrong and how can i overcome this

I have W7 and Ubuntu 12.04 on my PC.It's through wubi that ubuntu runs

Any help is appreciated,
Thanks in advance!!
