Ben,

Conflicts can still be an issue even if they are not running at the same time.

You will have to google the programs and see what they say they are at the designer's website.

In answering a previous post from you, I pointed out some of the rules for deciding what type of security you need to choose and go with it.....

This is all that I use on my computer for security. all are free and I choose to run them on regular basis and perform updates as well.

Avira anti virus program
Security solutions for private PCs

spywareblaster without the tea timer install
SpywareBlaster® | Prevent spyware and malware. Free download.

Ccleaner (for both registry cleaner and spyware cleaner) uncheck the yahoo toolbar option in the installation
CCleaner - Download

ATFcleaner cache cleaner
ATF-Cleaner.exe - www.atribune.org

Superantispyware
SUPERAntiSpyware.com - Downloads

winpatrol startup manager among other things as well
BillP Studios: WinPatrol 2009

comodo firewall
Firewall and AntiVirus Free Software Download from Comodo

****note*** I use only the firewall from comodo. it is now a combination suite with anti-virus protection. The AV is good but I use AVIRA and am happy with it. During installation you can opt out of installing the AV application.

This is all that I have installed for my security of my computer. Every once in a while I will run a rootkit application just to see if something got through. All these programs are the free versions and I run them on a regular basis......once a week on all the temp cleaning and cache cleaning applications. Once a month on the reg cleaning unless I install and uninstall software and I run it to remove any lingering files.

Not to get you to follow in my choices but to give you an idea as to what types of applications needs to be on a computer security
