Kaspersky Virus Removal Tool is a free software designed to detect and remove malware from Windows computers. The software scans the entire system for malicious programs, including viruses, Trojans, worms, and adware. It also offers a quarantine feature to isolate suspicious files and prevent them from causing harm to the system. The tool does not offer real-time protection but can be used as an on-demand scanner to complement existing antivirus software.
