Use a virtual private network (VPN). 

Installing a free VPN Chrome extension is a good idea since Chrome is the most used browser. This implies that a thief won’t be able to access your device properly. Because hackers will not know your IP address if you use a VPN, the amount of information they may get is limited. As a result, they won’t be able to get any more personal information from you while you’re browsing online, keeping you secure. 

Make use of strong passwords.

Make use of strong passwords. that combine numbers, letters, and special characters to limit the chances of a hacker guessing your login information. 

Spam email attachments should never be opened.

Phishing schemes are one of the most common ways used by hackers to obtain access to a computer. If you get an email from someone you don’t know or didn’t anticipate, don’t open the attachment.  

Above all, being aware is the key to staying secure online. If you believe you’ve been a victim of cybercrime, contact the National Crime Agency right away.
