Alfrex

Many thanks but unfortunately I try those steps before and not fix the problem, in the meantime I was able to solve with another antivirus , The strange thing is that on an older computer I did not have this problem, maybe it is a corrupted system file.

Hello community, I am trying to install kaspersky free, but I get a message that the digital signature is not found (the setup is from the official website) I attach a screenshot. Thank you in advance for your advice. I have windows 10 pro with active administrator account.
