I use XP Pro SP3 and I use Neutron to keep the system clock accurate. I run it once per day.

Neutron is a very simple and small time synchronizing program that retrieves the accurate time from one of several specialized time servers on the Internet. Once the network time has been retrieved the program can set your computer's clock to match it.

maslow,

Why is you system time changing to this extent?

If you get license disabled message, you should enter your license key into avast again, this should enable updates.
After that, you can update the program to latest version, there is a fix that reentering license key is not needed, just correct system time.
