Any views on compatabilty with Vista 64 bit

I have just upgraded my computer to 64 bit including Vista Home Premium 64 bit

I am renewing my Kaspersky Internet Security 6, licence and would be like to have your thoughts on the following:

AVG Anti Spyware 7.5
Ad-Aware Spy and Malware
SuperAntiSpyware

I will be also running SpyBot
Also currently have Ad-Aware 2007 but will replace with one of the above.

Be aware of Spyware Detector
Recently I tried the demo version of MaxSecure Spyware Detector. I got fed up with this programme asking for permission to update every time I started up my computer. I unInstalled the programme, deleted all its folder's, manually did a registry check and deleted all registry inputs, but it still kept coming up as an Internet request to update whenever I started up my computer. It got so bad that it stopped me being able to boot up until I had rebooted 4 - 5 times. I only got rid of it and restored my computer to its original after I did a system restore to a period before I installed the software.

As I do not want the same problem again do any of the above work in the same way as.

Thank's
