I have a fourth old computer that only has the standard antivirus for windows and this one nevertheless presented this problem.
I am testing another antivirus, I am curious how my home network is being attacked every week.
On the eset log the threat removes eset from the system entirely.
on the network the computers are not infected at the same time, yesterday when it happened again with one the other 2 will continue to function normally.
the infected computer yesterday he entered the windows login screen and quickly restarted, I even thought it was a memory failure, but when he returned he was already without eset, windows security center and update disable.
