Hi,
On my computer I've got an old Client Security product (installed in 2014) that I never changed because it was working well and updating.
But now, after being absent for a while, it tells me that I need to update my definitions, but when I go to "check for updates", it tells me that my product is up to date. I've got this for a week or so.
I've tried the reset tool from your guide but it gets an error, I guess it doesn't work on client security.
I don't want to uninstall it because I don't have any license key with me anymore, and I don't know if reinstalling it will keep my current license...
Can you help in any way ?
Thanks, Here are some screenshots and a fsdiag file.
