National Consumer Protection Week is February 28 – March 6, 2021. In our “virtual world” there are many things we need to be aware of to lessen our chances of being scammed, hacked or having our identity stolen. Here are some ideas to keep your computer safe.

              Scammers, hackers and identity thieves are looking to steal your information – and your money. But there are steps you can take to protect yourself, like keeping your computer software up-to-date and giving out your personal information only when you have good reason.

              Update Your Software. Keep you software – including your operating system, the web browsers you use to connect to the internet, and your apps – up to date to protect against the latest threats. Most software can update automatically, so make sure to set yours to do so.  Outdated software is easier for criminals to break into. If you think you have a virus or bad software on your computer, check out how to detect and get rid of malware.

              Protect Your Personal Information. Don’t hand it out to just anyone. Your Social Security number, credit card numbers, and bank and utility account numbers can be sued to steal your money or open new accounts in your name. So every time you are asked for your personal information – whether in a web form, an email, a text, or a phone message – think about why someone needs it and whether you can really trust the request.

              Protect your Passwords. Here are a few ideas for creating strong passwords and keeping them safe:


Consider Turning On Two-Factor Authentication. For accounts that support it, two-factor authentication requires both your password and an additional piece of information to lof in to your account. The second piece could be a code sent to your phone, or a random number generated by an app or a token. This protects your account even if your password is compromised.

Give Personal Information Over Encrypted Websites Only. If you’re shopping or banking online, stick to sites that use encryption to protect your information as it travels from your computer to their server. To determine if a website is encrypted, look for https at the beginning of the web address. That means the site is secure.

Back Up Your Files. No system is completely secure. Copy your files to an external hard drive or cloud storage. If your computer is attacked by malware, you’ll still have access to your files.
