What is mfeavfk?

The genuine mfeavfk.sys file is a software component of SYSCORE by McAfee LLC.
"Mfeavfk.sys" is McAfee's "Anti-Virus Filter Link driver," part of SYSCORE, a common group of ".sys" drivers and ".exe" processes used by McAfee For Enterprise cybersecurity products, including VirusScan Enterprise (VSE). It installs in "C:\Windows\System32". Stopping or uninstalling SYSCORE processes can cause serious problems. Certain ones automatically restart because malware often tries to kill them. Consult McAfee or system administration. McAfee's description of its functions for VSE 8.7i is "anti-virus scanning". VSE 8.8 adds "maintaining a file cache". "Filter drivers" are kernel-level drivers that become part of the Microsoft executive through the Microsoft Filter Manager. This is how McAfee can do On-Access virus scans automatically when files are opened or closed. Note that file backup or encryption products also use this technology and certain products can conflict and corrupt files. McAfee LLC is the world's largest dedicated cybersecurity technology company. Intel holds 49% ownership.

Bis auf die obige Info nichts, leider. Bei wiederholtem AVG-Virenscan gibt es immer den Hinweis auf diesen versteckten Treiber. Ich habe kein Programm von McAfee installiet, kann also auch n ichts deinstallieren. Mich nervt dieser stete Hinweis. Was kann man tun?

ich nehme fast an, dass AVG diesen "Fehler" selbst einsteuert. Habe einen Scan-lauf gemacht, den Fehler gesichertn Neustart wie gefordert und sofort einen neuen Scan gestartet mit gleichem Ergebnis. Malwarebytes Anti-Malware fand nichts.
