Downloading software from a source labeled is highly likely to infect your computer with the very threats you are trying to prevent.
While the legitimate IObit Malware Fighter is designed to remove malware, "cracked" versions distributed via torrents often include the following "features":
: These downloads are common vectors for ransomware that encrypts your files and demands payment for their release.
: The software may include hidden scripts that use your computer's hardware to mine cryptocurrency for the attacker, significantly slowing down your PC.
: They often bundle persistent adware that tracks your browsing habits and steals login credentials or financial information.
For your safety, it is strongly recommended to use the official free version from the developer or opt for reputable, free alternatives like Malwarebytes or Microsoft Defender.
: To make the "crack" work, you are usually instructed to disable your real-time antivirus, leaving your system completely defenseless.
