importance usb disk security software & deep freeze

Usb security software filters all known viruses and worms present in your flashdrive it scans the disk before it infects your system I had it for a quiet while and it is filtering those worms and viruses. Deep freeze also has a great advantage because it will difinitely restore your system from its state where the best configuration is. If you have executed a file and you were not sure about it and deep freeze is installed, then just by restarting your computer it will restore back to the point the executed file is notinstalled. How will you rate these software ? Are they very important than installing an antivirus to your system?
