Keep all software up to date including the operating system
Software isn’t perfect. It’s bad enough that bugs in the code occasionally make a program crash. What’s worse is that cyber criminals are constantly seeking flaws in operating systems and other software, vulnerabilities that will let them steal your passwords, install malware, and otherwise give you grief. For these reasons it is vitally important that you install the recommended updates. Recommended updates can also address non-critical problems and also make your computer and network perform better.
Install antivirus and malware protection
This will protect against viruses and malware that can come from emails, files on disks or downloads from the internet. Make sure to use the very latest version of your antivirus or security suite. The bad guys are always inventing new tricks to try to correct your Computer and network. If you’re using an old security tool you won’t have the new fixes. If you make certain to keep these essential programs up to date, you should stay safe from most known threats.
