How the hell do I get this off my work computer???

Back away from the keyboard..... get down on your knees and admit that you are powerless over your addiction.....

quit your job?

you can try going to http://www.anonymizer.com/ then do your surfing from there. Keep in mind that most companies have long since caught on to this site, and it is probably blocked too. Worth a try tho.

stop f*cking off at work. dumbass.
