I use Windows 98 and after using RegCleaner to delete various files I find that I cannot access Outlook Express and nearly all programs I have installed on my desktop including RegCleaner, Spybot, SpyGuard, Crazy Browser, and so on. I can access HiJackThis up to a point but the HiJackThis page will not open. For many internet applications and for non-installed new downloads I get the message " Access to the specified device, path or file is denied"
I can access IE normally. Any advice would be much appreciated.
