RegRun Reanimator is a free malware detection and removal utility from Greatis Software. It is intended for Windows users who need an additional way to investigate suspected infections, including trojans, adware, spyware and rootkits. It can be run as a standalone security tool or alongside another antivirus program, so it can serve as a second-opinion scanner when a computer behaves unusually or an existing security setup needs supplementary checks.
Its scanning process examines the system for malicious components and produces a report of its findings. Users can review the results to understand what was detected, then use the program's removal functions to deal with identified threats. This detection-and-removal workflow is useful when a suspicious program persists after ordinary cleanup or when several types of malware may be present. The reports also provide a record of the scan results, helping users decide what to investigate or remove rather than relying only on a general system status.
For difficult cases, RegRun Reanimator includes Submit State, which sends a snapshot of the computer's system state to Greatis Software's support team for analysis. This gives support staff information about the particular machine when offering guidance on a stubborn or complex malware problem. The program also includes auxiliary system utilities for managing startup processes and system services, along with tools for removing unnecessary files. These functions support basic system maintenance in addition to malware cleanup.
Typical uses include checking a Windows PC for threats, removing detected malware, and investigating a machine that remains slow or unstable after an infection. Its ability to work alongside other antivirus software makes it suitable for users who want a separate cleanup utility without replacing their existing security product. Scan reports and the support-submission feature can also help when a problem requires more investigation than a routine scan provides.
RegRun Reanimator is freeware and supports Windows 11 and Windows 10, as well as a range of earlier Windows desktop and server editions. The supported systems include both 32-bit and 64-bit editions where applicable, extending back to Windows XP and Windows Server 2003. It is a focused Windows security and maintenance tool rather than a general-purpose antivirus suite, and is best used as part of a broader approach to system security.
