Our verdict: Kaspersky Virus Removal Tool is a capable second-opinion scanner for cleaning a PC that is already infected. It runs without installation next to your antivirus. It has no real-time protection, and Kaspersky's Russian origin and the US sales ban may matter to you.
About Kaspersky Virus Removal Tool
Kaspersky Virus Removal Tool (KVRT) is a free on-demand scanner from Kaspersky, a security company headquartered in Moscow. You download a single file, run it and scan; it needs no installation, can run from a USB drive and removes itself from the system when you close it.
KVRT finds and removes viruses, trojans, rootkits, adware and riskware, including malware that blocks a regular antivirus from running. You can choose the scan areas, such as startup objects, boot sectors, system memory and drives. Before the first scan you must accept the license agreement, privacy policy and Kaspersky Security Network statement. The US government banned sales of Kaspersky software in the United States in 2024.
