You're welcome! You got the 'Bobbye Special'. Once in a while I take time out to help pare a system down. Usually works pretty well.

Of the programs you asked about:
Malwarebytes: Remove
CCleaner: Remove
Ad-Aware: Remove
SpyBot S&D: Keep
Avira AntiVir: Keep
SUPERAntiSpyware: Remove
ESET Online Scanner: Keep
HijackThis: Remove

On most of the programs I've marked 'Remove', you can download and run scan whenever you think you need to. You don't need them using hard drive space and RAM.

Add a good, bi-directional firewall(one software firewall I recommend either of these software firewalls.- both are free and good:
Comodo or Zone Alarm:

Consider these programs for Extra Security

• Spywareblaster: SpywareBlaster protects against bad ActiveX. It places kill bits to stop bad Active X controls from being installed. Remember to update it regularly.
• IE/Spyad This places over 4000 websites and domains in the IE Restricted list which will severely impair attempts to infect your system. It basically prevents any downloads (Cookies etc) from the sites listed, although you will still be able to connect to the sites.
• MVPS Hosts files This replaces your current HOSTS file with one containing well know ad sites etc. Basically, this prevents your computer from connecting to those sites by redirecting them to 127.0.0.1 which is your local computer.
• Google Toolbar Get the free google toolbar to help stop pop up windows.

If I can be of further assistance, please let me know. .
