You should probably use Google for this next time, but read the answer here.
Aside from what is stated there, get an antivirus like Avast or AVG (they are free and better than most paid antivirus programs), run that along with Malwarebytes' Anti-Malware and Spybot Search and Destroy once or twice a week. Remember to "Immunize" with Spybot Search and Destroy every time you use it.
Also, try not to use the Internet Explorer web browser. It has a lot of security holes and you could've gotten a virus from simply using it. Try using something more secure and overall better like Firefox, Google Chrome, or Opera. And some websites are bad even though you don't think they are, with Avast and AVG they give you a neat little icon for your web browser that shows the rating of each site you visit, and even warn you if they may be harmful. Along with that I suggest installing the extension called Web-of-Trust (WOT) because it does the same thing. Advertisements you see on websites can give you viruses too, I doubt any on Armor Games will give you any, but if you browse around the Internet often clicking websites and occasionally click on advertisements it could happen, so getting an ad blocker may benefit you. Can't be too safe, eh?
