Many people can hack into your computer with viruses or other malware. You can usually tell that a computer is not safe when files start to go missing, your computer is slowing way down opening programs, shutting down or restarting unexpectedly, frequent system crashes, lagging web browser, and malfunctioning antivirus programs and firewalls. When you have a hunch that your computer has been tampered with and has a virus, you should run a full system scan. Have an antivirus software run the scan to see if there are any threats. You should also have temporary files and then go into safe mode. That way, safe mode prevents specific programs from running to fix the issue. Then you should reinstall the operating system, like Windows, to clean your computer. To ensure your computer from getting viruses, you should have an antivirus software to protect your computer. That way, the software runs constant scans to detect any possible issues. You should also have complex passwords to protect your personal things. Maybe even include a multi-factor authentication; that way, you have even more protection in getting to your items. Have automatic updates for your apps, software, and hardware; that way, the computer can do it automatically, and you won’t have to do it manually. Also, watch out for scams like phishing.
