Hi. I had already tried this when ploughing through the list of "solutions" which I Googled, without success.
However, I tried it again and this time I found that I needed to take ownership of two files. I then attempted to uninstall again. This time
it stalled with the message "RegisterOutlookExpressPlugin failed". Having accepted the message, the uninstall continued and the program (Spamfighter) no longer appears under program files. What the message was all about I have no idea. I use Windows Mail on this laptop and it seems to be working fine.
