Antivirus Issues

Antivirus Issues

Common Symptoms

• PoB executable flagged as a trojan or malware.
• Installation or update fails due to antivirus interference.
• Application crashes or disappears after installation.

False Positives

Antivirus software sometimes mistakenly identifies legitimate software as malicious. This can occur due to:

• Heuristic Analysis: Antivirus software uses heuristics to detect new, unknown threats. These heuristics can sometimes flag benign software that behaves similarly to malware.
• Software Packaging: The way software is packaged or compressed can resemble the techniques used by malware, leading to false positives.
• Frequent Updates: Software that updates frequently, like PoB, might trigger antivirus software to flag it as suspicious.

Recommended Steps

1. Use Windows Defender:

   • If you're using a third-party antivirus solution that is known for generating false-positives, for example AVG, Avast, McAfee, or Norton, consider switching to Windows Defender, the built-in antivirus solution on Windows. Windows Defender provides robust protection and is less likely to produce false positives compared to some third-party antivirus solutions.

2. Add An Exception:

   • Add the PoB executable file to the exclusion list of your antivirus software.

3. Manual Installation:

   • If automatic updates fail, download the latest version manually from the Releases page.

4. Report False Positives:

   • Report the false positive to your antivirus vendor to help improve their detection algorithms.

Advanced: Scanning the Executable with VirusTotal

1. Visit VirusTotal:

   • Go to the VirusTotal website.

2. Upload the File:

   • Click on the "Choose file" button and select the PoB executable file.
   • Alternatively, you can drag and drop the file into the designated area on the VirusTotal website.

3. Analyze the File:

   • Click on the "Confirm upload" button to start the analysis.
   • VirusTotal will scan the file using multiple antivirus engines and provide a detailed report.

4. Review the Report:

   • Check the report for detections. If the file is flagged by a small number of antivirus engines, they are probably false positives.
   • Look for detections labeled with "ML" (Machine Learning). These detections often indicate heuristic or behavior-based analysis, which can be prone to false positives.
   • If a large number of engines flag the file, proceed with caution and report the issue to us.
