NIKUNJ VYAS, there're a bunch of free AV apps available for download. Suggest you pick one and run it ALL the time you're online for future protection (AVG and Avast update as things change, dunno about others, Google for locations). Most have a 'scan now' option which can clean your machine now.
In case you can't dl (some nasties block cleaners), there're some online cleaners (not quite as effective, but better than nothing). Post back if you need 'em, I have links.
