About two months ago i tried Panda anti virus out, and it seemed good. I decided to get the full version, only to realise it was not only the worst anti-virus ive ever had, but infact the worst piece of software id ever had. It kept restarting my PC after updating its self (3-6 times daily) and didnt pick up any viruses when i did a test by creating a harmless worm and downloading it.

I contacted Panda about this, and their response was:

"We are sorry that you cannot find a use for our anti-virus software"

That was it.

I think you perhaps had an install error which had caused these issues.
I've been running Panda for two years on this PC and 4-5 on another with no problems. Panda has never caused my PC to reboot-- without my direct involvement.
Just for curiosity's sake-- what did you run before Panda ?
Sometimes AV uninstalls -- as any software-- can leave "bits and pieces" of the old app behind which causes conflicts between the 2.
Anti-Virus apps are particularly prone to this... because of the deep levels they need to operate in within Windows (in order to protect you well)

I agree that the customer response was lame.
