herdProtect vs Kaspersky Virus Removal Tool

herdProtect is a free Windows desktop scanner intended to provide a second opinion alongside an existing antivirus product. Its cloud scanner uses 68 anti-malware engines, checks active files and auto-start locations, and can send unknown files for remote analysis. The site says that analysis of unknown files takes 5 to 30 minutes. Scans are on demand, with no real-time protection and no scheduled-scan option. Detected threats can be quarantined, but remediation is manual. Reports and other communications between the computer and herdProtect servers are encrypted. The service does not accept one-off or batch file uploads for analysis. The maker says downloads are not currently being distributed and invites interested users to email for a waiting list. Use is intended for personal, non-commercial purposes unless otherwise specified. Support is limited and listed at [email protected].

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.
