boot scan
About this tag
Boot scan is a security feature in antivirus programs like Avast that runs before the operating system fully loads, allowing detection and removal of deeply embedded malware that standard scans might miss. On WindowsForum.com, users discuss using boot scans to tackle persistent threats such as Win32/Zbot trojans, viruses that cause repeated alerts, and infections that block downloads or corrupt system behavior. Topics include scheduling a boot scan after a crash to check for memory faults, dealing with false positives during boot scans that quarantine critical files, and troubleshooting issues like drives becoming read-only after a reboot. The tag covers practical advice for running boot scans effectively and resolving post-scan problems.
