I'm running the latest Kaspersky Internet Security on my 6 mos old acer Windows XP system and it doesn't show any malware, but when I try to open my Outlook Express I get the message: Application or DLL c:\windows\system32\imm32.DLL is not a valid windows image. Please check this against your installation diskette. I reloaded IE7 but that didn't help. This seems to be a common problem so I bought PC Tools 'Registry Mechanic' but that didn't fix it. I opened Windows in Safe Mode and I can run Outlook Express from there if that means anything. Where do I go from here? Thanks for any input.
