Avast for my av
SuperAntSpyware for spyware
Malwarebytes for other malware
Windows Firewall for hacking protection
Now you can keep Spybot Search and Destroy if you are happy with that and add SuperAntiSpyware for added protection.
Remove Ad-Aware and replace it with Malwarebytes
Make sure you have Windows Firewall or something like Comodo Firewall running.
Warning with Comodo it has AV protection also but do not use it as having two AV running in Real Time can cause false positive reports and serious slowdown on the system. This would go against everything we are trying to accomplish here.
I suggest uninstalling Ad-Aware then trying the system to see if it boots correctly like you want. If so then I will send the links for the other programs to replace with. Please do not go to any sites or download anything other then what I give you to prevent any type of infection.
