The best way to protect your computer is to install an antivirus software. Such a program usually costs only a few dozen dollars for a subscription that lasts for a year. Antivirus programs protect computers from common threats such as malware, adware and spyware. The most important feature of such software is protection against viruses that can virtually paralyze your computer. All of these nasty attacks on your computer can steal personal information and delete important digital documents.
Antivirus programs will automatically block attacks that come when you visit rogue websites or open e-mails containing malware and viruses. Antivirus protection also runs regular scans to alert you of any risks on your device. For example, this program can alert you about tracking cookies that were installed on your web browser. Antivirus programs also alert you about how many days are remaining before your subscription expires and you become vulnerable to cyber attacks again.
