Avast Free Mac Security is Not Working! How to Delete it?

Let’s say; you are the owner of MacBook Pro with OS X of the outdated version. For a couple of years so far, you did not find it possible to upgrade the system to the latest releases. The situation is even more complicated if you do not live close to the Apple Support Center (some regions do not have official Apple representatives at all).

One of the irritating things that may happen to your Mac is an annoying Avast security message. Wait a minute? Isn’t Avast a Windows program? No, not any longer, meaning it offers several editions for different operating systems. Thus, Mac owners can use it too.

What is Avast All About?

Avast Free Mac Security offers malware protection. The developers promise almost no system influence in the background. It also has a password manager, but this function may be harmful depending on the circumstances.

Despite its promises, Avast can bring virus along with its installation package. It may start showing up all of a sudden, having no desire to go even in several weeks. You will notice it while surfing the Internet. It is especially irritating when this Avast malware appears up to ten times in a row with various URLs that it should actually block. Perhaps, the attempt to detect the problem using Avast built-in scan will result in nothing.

Here is the way the message looks:

AVAST!WEB shield has blocked a threat

INFECTION = URL-MAL

URL (random URL)

PROCESS /usr/bin/runlib

The problem is the URL is different every next time. The only things such URLs have in common are the /auupdate ending and the same PROCESS listed.

Expert and User’s Recommendations

Most probably, you have already heard people telling that it might be better to uninstall Avast and never use it again. Many malware and adware protectors are meant to be viruses themselves. The good news is Avast is free, so it won’t be that disappointing in case you find it a fake.

Of course, some people are on the side of the software. They really think Avast is not that bad and still capable of protecting Mac. They say the issue has nothing to with adware.

At the same time, you should keep in mind not that many users and professionals recommend Avast. Moreover, it may be harmful to your Apple computer. It deals better with Windows but still has many drawbacks. Like many other commercial security tools for Apple computers, the app sends private information (e.g., Safari browsing history and the text messages you share with someone) to its developer. A user will not have an idea about such machinations.

Moreover, Avast often ignores the real threats to your Mac’s security, allowing them in. It makes no wonder those who install Avast on their devices often receive false notifications, ridiculous warnings, ads, etc. The app will also expose the computer to network risks and corrupt the settings as well as file permissions. Finally, many users report a significant drop in speed and overall performance of their Macs. No matter how some of them tried to get rid of the nasty bug, Avast-related files and processes remain in the system, causing harm continuously.

How to Erase Avast Once and Forever?

You may try the easiest and most obvious way, which is following the developer’s instructions. You will have to backup data first before removing the application.

  1. Quit all associated processes.
  2. Go to the Avast’s Preferences menu.
  3. Click on a tiny lock and enter admin’s passcode.
  4. Uncheck (disable) File System Shield, Mail Shield, and Web Shield one-by-one.
  5. Close all windows and place the Avast’s icon into the Trash. Empty Trash.
  6. Reboot to see if it worked.

Mind that dragging the app’s icon to the Trash is never enough. Reinstall Avast and follow the developer’s guidelines above.

Other Things to Try

Get rid of the adware by:

  1. Installing, launching, and running a special free adware remover of your choice.
  2. Click Scan for Adware or its analogy.
  3. Erase the adware and escape the tool.

Another way is to

  1. Launch Safari or another preferred browser.
  2. Choose Preferences.
  3. Go to Extensions.
  4. Turn the suspicious extensions and add-ins off.
  5. Reboot Safari.
