HWinfo64 svm detection
#1
Hi Martin,

HWinfo64 detects my CPU as no svm function, although i have enabled SVM at BIOS. Is this HWinfo64 bug?
Windows Sandbox tested running btw.
Thanks.

Edit: CPU-Z has not detected AMD-V either  Huh

I don't think this is a bug in HWiNFO, it should be showing this properly and I verified it many times.

my other machine (using r7 1700, b450 i gbyte, latest BIOS) not showing svm either.. probably windows prevent your software then?

Can you check detailed features in the main window, especially "Secure Virtual Machine" ?

Hi Martin, 
I just turned off SVM at BIOS,  AMD-V appeared then  and 'Secure virtual machine' present  Huh

AMD-V in read means the feature is supported but disabled at BIOS level.
That's strange and looks like BIOS would be doing things upside down - with SVM enabled the system reports it's not supported.

Anti-virus software can "block" the virtualization features of modern processors, meaning that they use it for themselves so other software can't use it. Avast is known to do something like this (had a case with their Free Antivirus and VMware/VirtualBox some time ago). I can imagine that the OS can do something similar which prevents applications to use, or even see, virtualization.

JFTR, see this thread in the Avast forums: https://forum.avast.com/index.php?topic=162445.0 which also mentions where to find the option to turn it off in Avast. Other anti-virus software might have a similar option.
