Virus Removed Have To Stay Alert

From Yesterday My computer suffering from the worm or virus ( I don't know exactly which harms my computer ) . It gone hang and after that I shut down my laptop then my working css file's code was Removed . At that time i was using Webstorm as a IDE . After then I install Sublime Text and stay to coding . All files saved But that one specific Style.css was not changed ( I mean did not save ) . After While I got the idea then I go to the windows defender and click full scan button After a while It works . Then I Kept on Hacking on my stuff .
