Browser extensions may also be equally responsible for slowing down your Mac and for introducing the virus to your system. If you use Safari, go to ‘Safari Extensions’ and uninstall any extensions you do not recognize. 

On Chrome, click on the three dots on the top right corner. Go to ‘More Tools’ and then ‘Extensions’ and start removing extensions you deem suspicious. For Firefox, click on the three lines in the top right corner and click on ‘Add Ons.’ You can disable any and all extensions you think might be causing the issue. 

  1. Disable login items

Some apps launch as soon as you start your Mac, and this is where a virus may hide and cause startup issues. Disable all login items in Users & Groups. 

  1. Check your Downloads folder

The virus may be biding its time in your Downloads folder. Do a sweep and make sure every file in your Downloads folder has been downloaded by you. If not, delete it. If you are not able to delete it, it is a clear sign that you are dealing with a virus. 

  1. Create a new user profile

Viruses on a MacBook may be specific to a user instead of affecting the entire device. Try creating a new user profile to see if your problems go away. If it does, use the admin login to delete the user profile. Before you do this, you should backup all your data to an external device. It is a good practice to take regular backups to avoid data loss in such situations. 

As a preventative step, do not use the Admin profile on your MacBook. Create a standard user profile to avoid this situation.

  1. Perform a clean install

If the device is infected and a new user profile does not help, then it’s advisable to wipe out the device and perform a clean install of the macOS. Again, make sure you use Time Machine to back up your data or iCloud or a combination of both to protect yourself against data loss.
