You believe your computer to be clean why? Because your McAffee tells you so? Have you ever checked it with any other utilities? Granted, Comodo is one of the best firewalls out there (if not the best). But McAffee is far from being top shelf.

As for your statement :"A proper solution doesnt neccessarily mean five-six tools to scan for malware, some good sense and awareness will keep the computer clean.
You are correct to a point. A proper solution Starts with a good firewall. Then includes a good anti-virus, a good anti-spyware utility, (they are NOT the same thing) and a good anti-phishing filter (the ones included with your browsers are notoriously weak).
Inevitably though. The most efficient solution is to use a Good (ESET, Kaspersky, Sophos, or Webroot) Internet Security Suite. A good suite will not only provide you with more tools and options (things like Anti-banner, Anti-spam, IM Anti-virus, Network Attack blockers, and Parental Control to name a few). But, it will require less resources than running seperate and individual utilities.
Not for nothing but. I am a US Marine Corps trained technician. And, I do this type or thing for a living.
