WdfLoad is a Trojan Dropper designed to download other malware. Malwarebytes can detect and remove this trojan. This particular one was bundled with other software. WDFLoad creates a randomly named scheduled task that is intended to download and run a cryptocurrency miner. It will also store antivirus software certificates in the “Untrusted” section. You can read here how to check for and, if necessary, remove Scheduled Tasks. The full version of Malwarebyte would have protected you against the trojan, giving you a chance to stop it before it became too late.”]
