Trend Micro Internet Security Suite uninstalled but no re-install possible

I had to deinstall Trend Micro Internet Security Suite 2007 and after de-installing made a system restore to an earlier date. It didn't solve my problem and I restored back to where I was before.
When I try to re-install TMIS 2007, the installer st ill finds an earlier version, tried to de-install it and succeeds until it starts to scan drivers and services. then it aborts the de-install and re-boots,opens the installer again and round it goes, if I want to hours on end without getting anywhere.
I deleted (renamed and deleted) the folder containing the software
I stopped and deleted all running services related to the software
I cleaned the registry - and my registry cleaner has never let me down before
I searched the registry manually for keys related to the software and deleted them
I made a general cleanup - shortcuts, orphan files, tmp's etc.

Still no luck.
I posed the question to Trend Micro's support but haven't heard from them.
I thinks this is a general problem with firewall/antivirus/antispam/internet security software, they hide somewhere and very hard to get rid of completely.
Any ideas?

Okay on the CCleaner, use it myself but along with it use these two:

Advanced Disk Cleaner which is a freeware program, yes you will have to register but they don't SPAM you to death either.  Download from here: 

And this RegCleaner which is freeware and can be downloaded from here: 

I have been using all 3 of these for about 7 years now and they work great, only thing is if you are running Vista the RegCleaner won't work on it but the Advanced Disk Cleaner will.  I am still looking for a RegCleaner to use on Vista.

Here is the link to the Author's site of RegCleaner which has been updated to include a Vista RegCleaner and other tools if you are interested in checking it out.

Let me know if these solve the problem.  Thanks!

I forgot to say that Windows Security Center still announces that Trend Micro is providing the firewall and the virus protection although I cleaned everything up - so something's still hiding somwhere.

I have been using the "Issues" function in CCleaner ( to clean out registries for 2-3 years with great success.
