Bc20 isn’t a harmful app but some of the sites it may redirect to might be unsafe.Unlike Trojans, Ransomware, or Spyware infections, it really isn’t difficult to spot the presence of a browser hijacker in the computer. These apps are known for their ability to change the affected browser in different ways in order to redirect users to their sponsors’ sites. Some of the most typical changes introduced to the browser by such applications are changes in its search engine or a replacement of the addresses of the starting page and the new-tab page.

Remove “Bc20” will damage your computer from Mac

The following instructions will allow you to remove “Bc20 will damage your computer” in two ways:

  • The manual instructions will allow you to remove it on your own by downloading 2 software suites which will show you the folders the threat is located in. Installing, scanning, and deleting everything will require 1-2 hours of your time, depending on your speed and the threat itself.
    Note: If “Bc20” has an in-built ability to restore itself on a restart, the manual steps will not prevent that. We recommend the automatic removal.
  •  Download SpyHunter for Mac (one of the apps used in the manual instructions), scan with it, and if you decide to use the program, it will likely require about 15-20 minutes. This, however, requires an active subscription for SpyHunter, which means either to use the trial version or purchase the software.

Removal instructions:
1. Download EtreCheck from the Appstore and scan for any “Bc20” unsigned files. Delete them. (You can skip this step altogether and download and scan with Spyhunter instead if you don’t want to double-check things).
2. Download and install Spyhunter for Mac. Scan for any malicious files.
3. The app will show you which files are infected. Either use SpyHunter to delete them for you (the automatic removal) or do it manually, which means tracking down each detected location by yourself and deleting the file.
4. In most cases start with /private/var/root/Library/Application Support/.”Bc20″/”Bc20″
5. In Finder press Shift+Command+G to open the Find window.
6. Search for the /var directory. Then proceed and look for the /root folder inside.
7. It will most likely be locked and you will need additional permissions to meddle with it.
8. Press command+I and scroll to sharing and permissions. Add your user name to permissions.
9. Now you should be able to access the /root folder and proceed and locate the /Library folder inside it. Proceed to do the same until you are inside the /Application Support folder.
