ReadyNAS 104 will not shutdown

It locked again also with 6.2.2 so I decided to disable the virus checker and from that moment it seems that works.
What do you suggest? Leave like this and test some days or move to 6.2.4?

I guess leave it for some days and then update to 6.2.4 and test on that as well.

I personally don't see the point of the virus checker on the RN10x boxes, it really slows down your NAS and has no added value (just keep properly updates scanners on your PC's)

Unfortunately it happened again.
Last night I decide to update to 6.2.4 because I was seeing strange things (movie stop every 15 minutes and then restart, seem that lost the network connection for few minutes).
After the update it start again the same situation (lost network connection and impossible to restart the NAS, possible only unplug the power cord).
It happens 2 time in 5 minutes and one time the booting stop and was necessary to unplug again the power cord because the booting was frozen.
Now it's still working after 10 minutes but I don't think it's a normal situation.
Can somebody help me?

Just an updating: it happened again after half hour; in this way the NAS It is unusable
