Tricky !!!

When i try to install PC Tools Anti Virus Free Edition I get an alert saying Trend Micro PC-cillin Internet Security 2007 is present and it would conflict with PC Tools Anti Virus Free Edition so please uninstall it.
But the tricky part is I've never installed Trend Micro PC-cillin Internet Security 2007, in spite of knowing that I tried to search for it, I cant Find it anywhere in my PC.
What am I missing ?

Motherboard:
ASUSTeK Computer INC.
Product M2N32-SLI DELUXE

Operating System Microsoft Windows XP Professional 5.1.2600
(WinXP Retail)
OS Service Pack Service Pack 3
Internet Explorer 7.0.5730.13
Ad-Aware Anniversary Edition
ClamWin Free Antivirus 0.95.1
Advanced SystemCare 3 3.3.1

Spybot - Search & Destroy 1.6.2
ThreatFire

Do I need to inform Anything else....

 

Trend Micro.
Trying to install PCTools.
ClamWin AV showing up in the list.
How many?

 

I'm curios as to how slow the PCs running ... with all those security apps one of them has to conflict with another surely?

I actually haven't had any trouble with ASC (mind you I DONT use the registry cleaner) ... agreed about Ad-Aware and Spybot.

 

Remember that S&D has TeaTimer and SDhelper as realtime process also ...

Two that I have found conflict with each other are Nortons Internet Security and MalwareBytes ... MBAMs scanning time increases to five times its usual with NIS running ... alhtough SAS doesn't seem to affect NIS ...

 

You know what ... I think you're right my bad.

 

I realize this isn't the primary concern of this thread but since it was brought up, S&D Immunization and ThreatFire don't conflict. Just updated S&D with ThreatFire installed, no problems.

 

Did you purchase the machine new or used?
If new, may have been installed as a courtesy program by the seller.
If used, a leftover from previous owner.

 

No I don't have Trend Micro.
I only Have Calmwin,(no real time scanning support) so trying to install PCTools Anti Virus, thats when I'am told Trend Micro is present, which I am unable to find in my PC.

 

They dont as iam using both of them.
Its Trend Micro that doesn't like anything else to be present.

 

Purchased the components and assembled it myself installed the software I want. But I never found anything that says Trend Micro Pc-Cilin in it till I tried Installing PC Tools Anti Virus Free Edition.

Your thoughts on identity still have not been addressed,either.

 

Avira installed without a prob, worked fine. I liked it with Linux, but its too sensitive even my RTWlan is a suspicious program for it in XP where as the same thing is not a prob for it in Linux. Did not look any further uninstalled it.
I will give it another try, does it provide real time protection.

Thank You for the suggestion. Will certainly try it out.
