ZHPDiag is a free app that allows you to scan your machine for and diagnose if any malware, trojans, etc., are present. Use ZHPLite for diagnostic report analysis.
This tool is intended as an additional defense line to help you find potentially harmful items and should be used in conjunction with other removal tools once any adware, PUPs, trojans, viruses, or many different types of malware are found.
ZHPDiag is presented within a simple UI that allows for fast deployment and scan. Once it has finished the scanning process on your machine, it will provide a full report containing details of any items it found, allowing you to take the appropriate action to remove them. It can be a useful secondary look even after running other similar malware scanning products that may not have turned up any hits.
Consider using Malwarebytes for complete antivirus protection and to protect your devices, data, and privacy.
