they will be displayed in task manager(processes tab), if they are running; the only one I can remember is System Mechanic's "SMSystemAnalyzer" process;
for starters; how many processes do you have running? For comparison, I have 28.
Evilfantasy made a very good point:
All you need for security is an antivirus, firewall and I would also suggest using SpywareBlaster and WOT. They don't use much resources. The real security comes from being smart about what sites you visit and what you download. No program will protect you from everything.
basically, you should only be running what you need. Registry Cleaner programs are known to cause problems, and I personally have dealt with my fair share of them (some requiring a complete format/reinstall
)
many of the programs you are using are a bit extraneous, for example, "privacy guardian". I haven't used it myself, but chances are it's functions can be superceded by a good firewall/anti-virus.
Here is a good way of going about it; remove everything but the base level Antivirus and firewall programs of your preference and CCleaner as well as select other programs (WOT, and spywareblaster, as EF suggested). Run CCleaner a anti-spyware solution (ad-aware or Malwarebytes Anti Malware) every week or so, and defrag relatively frequently as well.
If you feel you need to reinstall on of the other applications afterward, do so, but make sure that you
need the program, as opposed to just wanting it (it's a fine line, really).
over time, you'll find that you haven't installed some of the previous applications you had, have programs installed that get used, and have a faster machine.
