W.o.T. Mega Hack Adware

CatStalker: Yes, mosts 'hacks' you'll find online, for any game, are usually viruses and spyware.
If you can, run Malwarebytes Anti-malware, and then make sure you have a current anti-virus program running. I usually recommend Microsoft Security Essentials since it's free and not to intensive on system resources.
And be careful on the internets, it's a dangerous place.
