i just installed threatfire and in my control panel-security panel-under virus protection
windows finds more than one antivirus program on your computer and at least one reports that it is currently up to date and virus scanning is one.....isn't that conflicting with avast! or not

don't have any others previous installed before-just avast and now threatfire

below from their threatfire tutorial....
can I use ThreatFire can I uninstall my antivirus protection?
Since no single application is currently foolproof, PC Tools believes that a layered defense provides the most complete protection. ThreatFire is the perfect complement to your existing antivirus, and will protect you between antivirus updates.
It is fully compatible with traditional antivirus programs, and can run side-by-side with these programs without conflict. While the traditional programs will protect only against known threats included in their signatures, ThreatFire goes beyond and protects against new or unknown zero-day threats as well.
ThreatFire also includes the on-demand scanning engine from PC Tools AntiVirus. This provides the perfect combination of on-demand scanning available in traditional antivirus with the cutting edge behavioral-based protection provided in ThreatFire for a powerful and comprehensive defense.
