Hello, I've used Malwarebytes for years but this is the firs time I haven't been able to find a workaround to running the program. Basically, when I double click on the Malwarebytes install file nothing happens. I tried installing TDSSKiller and it does the same which is nothing. The computer has McAfee installed but nothing happens when I try to run it either. Regular exe files do work, so its just the antivirus/antimalware software that's being blocked. HiJackThis has been the only thing that would run. Please help, thank you! FRST.txt Addition.txt
