I was uninstalling a prog that had a trojan in it. I deleted the registry keys and such; manuelling removing it because the Explorer.exe would shut down every time I tried to do it the old fasion way Wink So, I was going through, and I accidentally deleted the Uninstall registry key Which has led all the installed progs to not show up in the Add/Remove Programs gui that's in Control Panel. And so, I am wondering if I have to wait until tommorow to do this, when I have the windows cd. Or if I'm able to just do some other recovery. I restarted and held down F8, and did the "Last known good configuration" thing, but it said I had to replace hal.dll. I've downloaded the dll file, but I'm not very sure I want to replace it because I don't want to mess up the computer that is not even mine worse. Wink And so... What am I to do in this dillema? The programs work; obviouslly, I'm in Firefox at the moment. I'm going to be running a scan, of course, and already have, but I'm defintelly sure it wasn't the virus that did this; but my fat fingering talent of screwing things up worse then they already were.
