Multiple .exe files running *32, powershell.exe crashes, unable to open malware protecction .exe's

I have been having an issue the past week or so. I have multiple misc .exe's *32 running in my task manager that slow and lag the computer. They seemed to be started by a dllhost32. Then powershell stops working. Also I am unable to open any .exe programs that have to deal with removing malware or virus protection besides Immunet 3 and ADW Cleaner. Please advise where to go from here and what logs I should get.
