pc infected by Conduit

hi, I apologize for my incorrect English, I'm Italian and I use a translator. about a month have the computer infected with conduit, I have done several scans with antivirus, anti-spyware and anti-malware even in safe mode, but the problem is always there.

here is the list of programs used:

Avg antivirus 2014

Spybot S & D

Malwarebyte

Combofix

please help me, I do not know what to do! among other things, some programs such as Photoshop CS6 no longer opens, gives me an error and also the browsers that use direct me always toolbar conduit. I want to make another example, I had installed in browsers of the Mozilla-Firefox's toolbar IMVU, a 3D chat, then one day opening the browser when I saw white, everything was gone, so I uninstalled and when I tried to install conduit toolbar on directing me, at that point I gave up.
