In one sentence, describe what the following article is about:

Parental controls generally leave sites like Google and Bing accessible. Virtual Private Network (VPN) software is designed to mask your computer’s location and can help you bypass parental controls. VPNs are commonly used for those who wish to browse the web more securely or privately. There are many free VPNs each with their advantages and disadvantages. Some free VPNs include the following:   Hotspot Shield includes both free and a paid premium subscription. It's easy to use and has a data allowance of 500 MB per day. The only downside is you must provide a credit card and sign up for a free trial of the premium version, even if you plan on using the free model.  Tunnelbear is another easy to use VPN that is owned by McAfee. The downside to the free version is that it only offers a paltry 500 MB per month.  Proton VPN has a free option that includes unlimited data per month, but only allows you to connect one device. You can sign up only using an email address and it does not log the websites your visit. It is also one of the few free VPNs that have no ads on the client.  Hide.Me has a free option that includes a 2 GB per month data limit and only allows you to connect one device. However, it does not keep website logs or user data. It also has no ads. Once you find VPN software that is suitable for your needs, download the VPN client and install it.  Read the terms and conditions for any VPN software you download. Some free VPN clients contain malware, intrusive ads, and may track you on the internet. As a general rule, only download files from reputable, first-party sites. Third-party downloads run the risk of infecting your computer. Most VPNs have an app that allows you to activate the VPN. This will start routing all your internet traffic through another location. Open a browser and try typing in a previously-blocked site. You should now be able to bypass the parental controls!

Summary:
Open a search engine of your choosing. Search free VPN software. Download VPN software. Activate your VPN. Confirm that you have unrestricted browsing.
