Avast Antivirus: Testing whether Avast Antivirus protects your PC against malware

How to test if Avast Antivirus protects your PC against malware

Some types of malware attempt to disable your antivirus protection. To verify that Avast Antivirus is working properly on your PC, use EICAR Anti-malware Test File. You can test the following components:

Testing Web Shield

Avast Antivirus Web Shield protects your system from malware while you use the internet (browsing, downloading files, etc.). If malware is detected while downloading a file from the Internet, the download is stopped to prevent the threat from reaching your PC.

To verify that Web Shield is working properly, follow these steps:

  1. Open the EICAR website and go to the download page in the Anti-Malware Test File section.
  2. Scroll down to the Download area using the standard protocol http section and click the eicar.com link to initiate the download.
  3. Avast displays an alert: Threat blocked (Infection: EICAR test-NOT virus!!!), which indicates that Avast Antivirus protects you against malware.

Testing File System Shield

The File System Shield in Avast Antivirus checks any programs the moment they are started, and files the moment they are opened, saved, or copied. If anything suspicious is detected, it stops the program from starting, or the file from being opened, saved or copied, to prevent any damage to your PC and data.

To verify if File System Shield is working properly, follow these steps:

  1. Temporarily disable Web Shield (Stop for 10 minutes), by following the instructions in the article below:
    Web Shield turns on automarically after the selected time. If the EICAR test finishes earlier, go back to Settings → Components and click the slider next to Web Shield to turn it back on.
  2. Open the EICAR website and go to the download page in the Anti-Malware Test File section.
  3. Scroll down to the Download area using the secure, SSL enabled protocol https section and click the eicar.com link to initiate the download via secured HTTPS.
