#5 – Remove Viruses From Your Computer
Computer viruses can cause slow performance and even crash your system. You probably know you should avoid opening unusual files that you receive via email or otherwise, as they can contain viruses. However, most people end up with viruses on their computer one way or the other, and it’s best to check for viruses regularly and remove them as soon as possible. You can download free antivirus software like “Avast Antivirus” and check for viruses every couple of days.
