So freaking frustrated

I bought this computer so I could fucking play games on it as well as do homework. Being so lonely, I thought it might be fun to play some computer games. I wanted to play Borderlands. I was going to go buy Borderlands, was getting ready to go in fact, when a friend emailed me and asked if I wanted to try his copy before I bought it.
He brought over an external hard-drive and installed Borderlands but it would NOT open.
Turns out if you have AVAST anti-virus, it uninstalls Trusted Installer. "not-so-trusted-installer says WHAT?"
LOL, fuck! Now he has got to come by and install Windows 7 for me and we hope that will fix the problem, and I'm thinking about trying some other anti-virus. I don't know. All I know is I have a fifty dollar game on an eight hundred dollar computer and I can't FUCKING PLAY IT.
ggrrrrr oh well. off to bed. I'm going to go fucking read.
