I have been using wordweb pro software in conjunction with spybot for a year without issue. I have been using spybot for the better part of 5 years, Now I get a report from spybot saying this program contains malicious software?

Is this a false alert?

The software is called "Wordweb pro" and can be found here: http://wordweb.info/

The software allows me to look up definitions of words on web pages.

Can someone please tell me why I am no longer allowed to use this software and why spybot deletes the exe file?

Thank you very much

Danny
