Make sure to download recommended updates from your device manufacturer or operating system provider, especially for important software such as your internet browser. Antivirus software, antispyware software, and firewalls are also important tools to thwart attacks on your device. Take advantage of automatic updating when it's available. Antivirus software protects your device from viruses that can destroy your data, slow down or crash your device, or allow spammers to send email through your account.
Update your browser with the latest version. Updated browsers have built-in protection against fake sites and viruses. These updates can eliminate software flaws that allow hackers to view your activity or steal information.
Get the latest anti-virus or security system software (firewalls) to protect you against online hazards. There are some operating systems that have built-in firewalls that may be shipped in the "off" mode. Confirm that your firewalls are switched “on” and keep all software updated.
Don't use USBs or other external devices unless you own them.
To avoid infection by malware and viruses, ensure that all external devices either belong to you or come from a reliable source.
