Malwarebytes' Anti-Malware is one of the best detection packages for locating malware on a system. A full drive or system scan for malware can take upwards of an hour depending on the size of the hard drives and whether they are SSD or regular hard drives. There is a FileAssassin utility within the More Tools area that can help to access locked files that are preventing their own deletion. The software is updated frequently with new detection files to be able to locate the latest malware that has been released on the internet. The free version is just as effective for finding and removing malware as the paid version; the paid version has more features.
