What are the most common Comodo errors?

As in the case of most software, a set of common errors or a set of most-encountered errors will be evident across time.

The situation is no different in the case of Comodo, so here are some of the most common errors to plague this software:

  • Error 2 (net::ERR_FAILED): Unknown error
  • Error: 000004c0: The format of the specified password is invalid
  • Error 200: User limit exception
  • Error 1002: Alias already exists

➡ Unable to find previously installed app or extension 

This Comodo error is displayed when the browser cannot see an app or extension. For example, this error can occur because the app has been uninstalled or removed from the site for one reason.

Another cause could be a corrupt Comodo user profile. You can fix this by creating a new profile using the following steps: 

  • First, press the WIN + R key combination.
  • When the Run dialogue opens, enter the directory for your system version.
  • Click OK, and a new window will open.
  • In the new window, rename the Default Folder to Backup Default.
  • Relaunch the app, and a new default folder will be created.
  • Replace the default folder with the backup details.

➡ Comodo won’t open at all 

Due to the interference of another antivirus or firewall application, the Comodo Antivirus may be prevented from opening on your computer.

To fix this, first, disable the antivirus and firewall application. Then, change the antivirus and firewall applications settings to safelist Comodo.

Finally, reactivate the antivirus and firewall applications, and you should be able to use your device usually.

2. Update Comodo AV
