Lots of people are having problems with Winring0, which Aquacomputer has apparently repackaged into the AquacomputerService.sys driver in the X.83 update. This driver code is getting flagged by Windows Defender as a Severe Threat because Winring0 is an unsigned Kernel-mode driver. Aquasuite uses this driver for all of its hardware monitoring. There is a thread about it on the English forum
HERE and a bunch of posts about it in the New aquasuite X thread starting
HERE. There are more posts about this problem in the German forums
HERE and
HERE. Microsoft cracked down on this unsigned Kernel-mode driver back in April, then backed off because it is used in multiple programs. In March, Aquacomputer said they were working on writing their own Kernel-mode driver and getting it certified by Microsoft. This still has not happened and now Microsoft Defender is flagging it again.
