OK, to explain it a bit:
iAVS update = the virus database update
Program update = update of the whole program (including the virus database)
iAVS update normally never wants a restart of anything, and is much smaller (and takes place automatically). Program updates are larger, and usually require a reboot of the machine.
Versions prior to 4.1.280 (the latest) had some bugs in the iAVS updater. Uprading the program to 4.1.280 should resolve all the issues.
