Malicious software are often hidden in compressed files, to avoid detection by your antivirus
- You can configure Avast to perform a scan of your compressed files, during the extraction process (a period during which the malware can infect your system):
- Here's an example (for 7-zip files ,but note that this rule also applies to different type of containers ... event the ISO files)
- Open Avast > Real-Time Shields > in the right pane, click on the "Expert Settings'' button
- In the new window, move to the "Packers" section and check the type of "archive files'' to be monitored.
- Validate with the OK button.
