yes to kaspersky and and yes to malwarebytes. if your AVG anti-spyware is uptodate then yes to SUPERantispyware (if you cant update AVG antispyware because, for example, it is outside its trial period then uninstall it (not the AVG antivirus) and leave SUPERantispyware).
Should I uninstall the Kaspersky scan, SuperAntiSpyware, MalwareBytes etc?
keep it updated (check each week) and it acts as a shield.
I had Spyware Blaster before but could never figure out how to use it.
we uninstalled it earlier in the fix, you should now have the uptodate version
I reinstalled SpyBot S&D because I couldn't find it, I think I uninstalled it in error
