Which software are you referring to? Malwarebytes is a legit malware/antivirus program. I’m assuming “spyhunter” is what it is flagged to be but even if it is not, Malwarebytes flags PUP’s, and if the users selects, quarantines them. It (or similar) is required for any non-technical users on WIndows as Defender and most 3rd party antivirus let crap that screws up your system get installed as it isn’t technically a virus. Toolbars, adware programs, etc. Had to install it on my mom’s system after she installed the software for her fitbit that wasn’t from fitbit. It constantly dowloaded other adware programs and made her system unusable. Had Bitdefender running and it did nothing to prevent it but Malwarebytes removed it and has prevented her from installing other things.
