Buffer overflow of LogonUI (Win 10 22H2) is a sign of attack, right?

[QUOTE="Victor M, post: 1014176, member: 96560"] Hi fellow Malwaretipsters, Is a buffer overflow warning for LogonUI a sure sign of an attack? I installed BitDefender Total but rebooting got me a bluescreen, there is no way to get back into Windows. So I reluctantly re-imaged from golden image. But when I boot up after the re-image, I got a buffer overflow warning from Windows for LogonUI. This looks to me like a sign of attack, stemming from my installation of BitDefender. Maybe the initial download of BitDefender duing setup something slipped in beside it. And the malware managed to persist after a re-image, and needed access to my system again. So it buffer overflowed LogonUI, which is run by System. So I zero filled the SSD and re-imaged again. No more funny warnings this time around. [/QUOTE]
