Malwarebytes Chameleon can remove malware from an already-infected PC
If malware somehow manages to penetrate your PCs defenses then it’s easy to assume you’ll simply download some other antivirus tool to remove it. But life may not be so straightforward. Once installed, some malware will try to prevent you from reaching big antivirus sites, and downloading or running their tools, making the problem much more difficult to tackle.
Unless, that is, you have a copy of Malwarebytes Chameleon to hand.
