How to use Antimalware Scan on ArchiveThanks to Antimalware Scan Interface (AMSI) from Windows 10, Bandizip provides a feature of antimalware scan on an archive, which can detect malware in the archive without decompression. CAUTION
How to useOpen an archive with Bandizip and click Scan in the toolbar. You will be notified if any malware is detected. ![]() About Antimalware Scan Interface (AMSI)Taking countermeasures against malware is a very important issue in the PC environment. Microsoft has introduced Antimalware Scan Interface (AMSI) accordingly, a standard which allows software to call other Antivirus software (AV software) and perform a scan for malware. ![]() Thanks to AMSI, the antimalware scan can be performed using only the content in memory and there is no need to store any infected files in storage. Bandizip scans an archive with AMSI and detects malware in the archive without decompression. Learn more
AV Software supporting AMSIAMSI is available on Windows 10, and Windows Defender which is a built-in antimalware component of Windows 10 supports AMSI as well. Even when you are using other third-party AV software, Bandizip can perform the antimalware scan using AMSI if the software supports AMSI. The following AV software supports AMSI: (As of June 2021)If the third-party AV software which is installed on your system does not support AMSI, AMSI becomes disabled or fails to work properly, and Bandizip cannot perform the antimalware scan. The following AV software does NOT support AMSI:Why does archiving software need to provide a feature of antimalware scan?Most AV software can detect malware (such as viruses and ransomware) hidden in an archive. Because the AV software is not archiving software, however, the antimalware scan on an archive performed solely by AV software may fail in the following circumstances:
Archiving software such as Bandizip, which does specialize in handling archive files, can provide fast and accurate malware detection with a scan optimized for the characteristics of the archive. Sample files for detection testsThe sample files below are not detected as malware by most AV software. The following links provide detection results of the sample files from VirusTotal. You may find that the sample files are hardly detected as malware by AV software.
NOTEThe samples provided in the links are EICAR test files and NOT actual malware. You may learn more about EICAR in the links below. LimitationsThis feature may fail to detect malware under the following conditions:
This feature cannot detect malware under the following conditions:
TroubleshootingIf AMSI initialization fails, try the following steps to solve the issue. ![]() 0x80070015. The device is not ready.Real-time protection is currently off.
0x80070103. No more data is available.The AV software on your system does not support AMSI. Uninstall it and install other AV software supporting AMSI instead, and then try again. (Windows 10 comes with Windows Defender, built-in AV software supporting AMSI.) |
