sorry, this is just wrong. there were no changes. if a virus gets stuck at the welcome screen something went wrong updating it (or the unit has a hardware problem which is unrelated to the OS version installed). try to boot it holding the EXIT key so you boot into the BIOS mode. then use Virus Control Center to update it again. if you cannot manage, contact support.
Something on the software side of things changed.
By replacing the motherboard battery it solved the issue of the virus getting stuck after the DC power had been removed and after the version 4.X.X.XXX update.
I know now that my battery was dead from day 1 as it never saved and user made patches..
I now know that my TI eats batteries in less than a few months, which is prob why it was dead from the start.
Has this come up since?
