From my previous post in this forum called "on a roll": The trojan was using, powerpoint.ini, WMplayer.exe and others. I deleted all the reminents but did something wrong as I got into the registry. I used RegRun trojan process analyser and found the troojan was using a certain key,HKLM\System\CurrentControlSet\Control\CommAlias and promptly deleted the COM2 part of it. None of my exe's work now and I can't open any file that needs an exe. I cannot even get the original rundll32.exe off my original win98se disc. What do I do now? thank you!!! PS-I can't download a zip file becasue when I go to open it the same thing happens where the extension association will not work for any .exe. I can't even run a exe file from the net as in "open" option instead of saving it to HD for same reason.
