I did notice there was a file on my computer that I did not mean to install. I had just started to use Limewire and was checking out the controls. I hit by mistake a download. It downloaded very fast and was gone. I didn't hink much about it at the time and was ready to log off . The next day the problem started. I just ordered PC-Cillin and ran a free scan from Trend...Nothing found thus far. When PC-Cillin downloads I'll do a complete scan.
