I deleted all the Azureus stuff in Safe Mode, and I now have about 1.5 gig free, but I used to have between 20 and 30.
I have Norton internet Security, and I don't download an excessive amount using torrents, I don't do movies or anything too big.
I probably don't need all the programs on my computer, I'll go through and delete some. But it's never been a problem before this happened. Just out of interest, how do you know how much stuff I have on my computer?
