... And how did it get on my system without me knowing? Why do I now get this message

sometimes when opening a file/folder (and always when invoking a shortcut within program folder to IPSwitch programs/features).
The only this changed recently was update of IE, download/install of XPProSP3, and (a couple days ago) install of System Mechanic Pro 9. Assuming IP refers to Internet Protocol, and Switch refers to switch, it would seem that the program (yes, the shortcuts were traced to the Programs sub folder but haven't yet found the executable file) has something to do with internet browsing...but the message generally appears when the system is not connected.
Can anyone suggest how to resolve the problem: make message stop appearing; reload the program to run properly; ...?
Note: the problem does not appear to be malware related:
When OK is invoked (see above pic), the program "excuses itself" and closes...from which "user" can proceed as normally.
