Not sure if this is happening for anyone else but when I click a link to get to the Unitronics forum through Google search it redirects to another website and tries to install spyware. This only happens the first time the link is clicked though; subsequent clicks go to the forum proper. I tried this on multiple computers and the same thing happened.
Example:
1. Search google for: "visilogic hide"
2. Click on a result to the Unitronics forums.
3. Instead of going to Unitronics forum, redirects to "url4short" or something and will try to install software.
