Thanks guys, for your advice, really appreciate it!

Installed in my computer:
Anti virus - AVG free
Firewall - Zone Alarm free (got older version 6.5, don't know if I should update to the new one as the size seem so large, pls. advise)
Preventive- Spyware blaster & Spyware guard
Scanner- AVG Antispyware & Spybot

I only have the free version of Winpatrol, should I install Avorax shield?

Sometimes reading the websites of the security programs makes me confused & a bit “paranoid”, your advice really helps, thanks so much. Have a nice weekend

p.s. curious if Comodo BOClean do okay?
