IObit Malware Fighter Free (formerly IObit Security 360) is a free application that allows you to comprehensively protect your computer against spyware, advertising components, Trojans, keyloggers, bots and various types of worms and viruses. Compared to its predecessor, the program is much more detectable and effective in the fight against malware, mainly distributed via the Internet. It features an improved dual-core scanning engine and a heuristic protection mechanism to protect your computer from new, yet unknown threats.

For the latter, IObit Malware Fighter offers a new heuristic algorithm called DOG (Digital Original Gene), evaluating the main attributes associated with software development, distribution and advertising. IObit Malware Fighter Free allows you to scan computer content in up to 3 modes: Fast (the most important parts of the system), Full (the entire space of all hard drives in the computer) and User (only the locations indicated by the user).

The program also gives the possibility to carry out the so-called autoscanning at a planned time or when the system is idle. The built-in real-time protection module covers such elements as system start, browser, network, files and cookies. The Pro paid version additionally protects active processes, used USB drives and detects threats by analyzing harmful activities.

A novelty in relation to its predecessor is the ability to examine suspicious files in the cloud, on external servers of the manufacturer.
