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

[QUOTE="Victor M, post: 1014254, member: 96560"] Actually I install very little software. What I was doing back then, was that I restored from Win 11 golden image for reasons I have forgotten, and then decided to try AVG Free. The AVG episode may have been a false positive. After it 'cleaned' out the in memory malware, I left the machine alone ever since then. Then a week ago I bought a new laptop to run Win 10 because Win 11's Software Restriction Policy is kaput, and also because I need a 'reference' Win 10 machine to physically look at when I answer forum questions. As per usual, I installed, then hardened, then made a offline state golden image. I left the new machine alone for a week and then decided to install BitDefender Total because I have a 2 yr license. I usually leave out installing an antivirus until I have hardened the machine and made an offline state golden image. That's because AV installations needs to be done online and there is a risk there. The risk being a) I sometimes have to turn off OSArmor, and b) I have to allow unknown bits and pieces of the installer to run on my machine, and some of those bits can be unsigned. c) thus you are running your admin account online, with your protections turned off and allowing 'unknown' software to run. If that is not risky, then I don't know what is. Well, if the Win 10 LogonUI is a known Win 10 problem, and if the AVG episode is a false positive, then I am not being attacked and it's just paranoid old me. Every time when things don't work as usual I blame hackers and try to beef up my defences. That's my version of 'assume compromise'. [/QUOTE]
