Getting ERROR 577 starting F-Secure Ultralight Services
From nowhere one computer in my network does not start F-Secure propely anymore and constantly asks for a system restart.
Three services, F-Secure Ultralight Network Hoster, F-Secure Ultralight Hoster and F-Secure Ultralight Protected Hosted, won't start. When I try to force I get the message "Error 577: Windows cannot verify the digital signature for this file.A recent hardware or software change might have installed a filed that was signed incorrectly or damaged, or that might be malicious software from an unknown source"
I tried to reinstall f-secure, but the problem persists. The Manager shows nothing adnormal. Windows Firewall and Defenfer are desable.
Can someone help me to figure out how to solve this?
Windows 7 SP1, Client 14.22
