My brother fixed my computer

I had to always hit Ctrl+Alt+Delete during start-up or I would be stuck before I got my desktop. My brother was up for last weekend and got me an anti-virus program. It fixed that problem. It said that 3 were still there and it couldn't turn them off. I said thanks, it works much better now. He kept playing around until dial-up wouldn't work. I figured i could call Intergate (my ISP) and straighten that out. He got up before me today and put in my "Restore" disc. I still had to call my ISP. Had to download Netscape 7.1 (1 1/2 hours) Have to still put in my printer and Sony disc adapter for pictures. Worst is it dumped all my files in Briefcase and Documents. (over 500 photos). Lost Irfanview and all other media players I had. Fortunately I can get some images back from DG. Not high res. but still the image. (SIGH) Frank
