Can a malware infection cause Avast Antivirus to fail to open?
Yes, a malware infection can cause Avast Antivirus to fail to open. Some types of malware are designed to target and disable antivirus software, allowing the malware to operate undetected on the system. If Avast Antivirus is unable to open, it’s possible that malware has infected the system and is preventing the software from running.

How do I fix Avast Antivirus if it won’t open due to a conflict with another security program?
If Avast Antivirus won’t open due to a conflict with another security program, users should start by identifying the conflicting program. This can often be done by checking the system tray or task manager to see if other security programs are running in the background. Once the conflicting program has been identified, users can try uninstalling or disabling it to see if Avast Antivirus will open. If the conflicting program is another antivirus software, users should ensure that it’s fully uninstalled and that all associated files and settings have been removed.
To prevent future conflicts, users should ensure that only one antivirus program is installed on their system. Running multiple antivirus programs simultaneously can cause conflicts and reduce the overall effectiveness of the security software. If users need to run multiple security programs, they should ensure that they’re compatible and configured to work together correctly. Additionally, users can try configuring Avast Antivirus to run in compatibility mode or with administrative privileges to see if this resolves the conflict. By taking these steps, users should be able to resolve the conflict and get Avast Antivirus running again.
