Kaspersky Virus Removal Tool vs Microsoft Defender Offline

Kaspersky Virus Removal Tool is a free, on-demand utility for scanning an infected computer and removing viruses, adware, riskware, Trojans, and rootkits it finds. It runs only when started and does not provide continuous background protection, so Kaspersky presents it as a possible second opinion alongside existing security. No installation is required: it can run from a USB drive and removes itself when closed. Kaspersky says its disinfection technology targets active infections, including malware that resists removal or blocks standard antivirus software. Scan choices include startup objects, boot sectors, system memory, and hard-drive volumes. Quick Scan checks memory, startup objects, and boot sectors; custom scans can cover full systems, selected directories, system volumes, or all volumes. Kaspersky describes the utility as intended for infected Windows computers, while Linux support is listed for its unpacker and command-line options. The tool alerts users when updates are needed, and updating requires an internet connection. Online technical support and help documentation are provided.
