Everything went fine until I downloaded CWShredder. When I tried to install it, I got a message labeled "External Protocol Request" warning that "An external application must be launched to handle file: links. Requested link:
followed by a warning that "this may be an attempt to exploit a weakness in that other program." I did not install the program.
I then downloaded Spybot and got a similar message when trying to install it. The message was the same except that it ended with spybotsd14.exe.
Should I install these programs dispite these warnings?
