GetSusp is not a malware removal tool per se, it merely detects suspicious entities and submits them for analysis to McAfee Labs.
By McAfee Free do you mean McAfee Antivirus courtesy of your ISP or PC maker?
There is danger running 2 antivirus applications together, yes, as they can cancel each other out. Decide which one you want to keep and uninstall the other one.
You can however run some anti-malware or anti-spyware software and I list a few I would recommend in the last link in my signature below.
I recommend you run Stinger and MalwareBytes Free both listed in that link.
Deleting from Program Files only partially removes something and could present problems later on with removal being foiled by missing elements of the software/malware. If they aren't listed in Programs in Cointrol Panel for normal remova; then leave the removal to something like the tools I mentioned.
