How much is my computer at risk?

I have:

PC Tools Spyware Doctor (free google pack version)

AVG Anti Virus Free Edition

AVG Anti Rootkit Free

PC Tools Firewall Plus (unregistered)

PC Tools Threatfire (unregistered)

McAfee SiteAdvisor Free Edition

Please give me reasons why and a rating out of 10 (10 being at risk and 1 being safe)

AND

Any recommendations?

I'm a cheapskate as well so free programs would be nice!

Personally I would replace all of that with, for example, Avira Antivirus, Spybot S%26D, and Zone Alarm - all free and with regular, free updates.

You've gone a bit over the top and it will slow your PC down.

There is no 100% protection but I would say you get 8 out of 10 for trying :-)

all this is making your computer strong and safe, but be care full that your computer will not crash as everything is working all together

the worst thing that can happen to your computer is getting really slow

Also try not to free download too many free safety software and try to buy them from quality PC shops.

You might be downloading a virus instead of protecting it or might be downloading something not use full and wastes memory.
besides those security tools, if you want to know how much your computer is safe or at risk, just get this PC Security Test free and interesting tools from here...
