A USB WriteProtector is a special type of software that automatically prevents a file from being saved on the hard drive when it is read by another computer. This software is programmed to save all user files in a file or folder and to prevent them from being overwritten. The idea is to protect your data if something happens to your PC. As you already know, there are several programs that will do this for you. You can usually get your files backed up for free, but if you want 100% protection then you may have to pay a fee. It is wise to spend a few dollars if it means the difference between saving your data or not.
In addition to protecting your files, a USB WriteProtector will help protect your operating system. This can be accomplished by running the program after you have installed a new program on your PC. If it has been installed recently it may not run well on the old machine. This is why you will need to use the software to ensure the computer is safe from viruses and malware. You should never run a virus program on your computer without any backup software. This is the only way you can protect your operating system from malware and viruses. This is also one of the best ways to keep your computer safe from spyware.
If you have decided to get the software for yourself, you will need to download it to your PC. There are plenty of downloads available online. Some are free, while others come with a free trial period. It is best to use a website that offers a free trial, but you may want to do some comparison shopping so you know you will get a good deal. You can download the program and run it immediately on your computer.
