Yeah, the application itself is fine, it just has the usual adware that is installed alongside a lot of freeware nowadays (a disgusting trend). You have to make sure to select "decline" when it asks if you want to install the toolbar, etc.
Spyhunter finds Bluesprig toolbar reinstalls itself each time you run Jetclean. This toolbar is spyware. I ensured that toolbar installation was declined during install of Jetclean. Jetclean does a good job of cleaning and I am sad that Bluesprig includes this spyware with a really good cleaner.
Thank you for the report. Our check for viruses also identified the program as suspicious.
