How to Avoid Malware During Cyber Monday

While you are obviously going to need a computer to surf the web, you are also going to need it for something else. Luckily, there are a few ways to avoid malware during Cyber Monday.

The most important thing to do is to stay up-to-date with all of your software and settings. Software vulnerabilities have been the leading cause of attacks on US systems for quite some time, and hackers use them to infiltrate your system and steal sensitive data. This includes most Microsoft software, but not all. To stay safe, you want to make sure that every application you use is protected, and that you install the latest updates before you surf the web. If you are in the US, you may want to purchase a Cyber Security Activation Certificate. These will allow you to log into websites that require the certificate, such as bank websites, so that you can see the full details of a site before you click any links.
