The free version of USB Firewall is a great software to use to protect your PC. It is an extremely powerful piece of software that is able to stop programs from running without your permission. This is done by locking the programs out of running on your PC without your permission. There is also a free trial of USB Firewall that allows you to check out its features and capabilities and decide whether or not it's going to be a good fit for your needs.
To protect your PC, USB Firewall uses a number of different methods. The software scans your system and finds all possible ways in which programs may run on your system without your permission. If you suspect any programs are trying to run on your PC, just double-click the program you want to block. You will be presented with a list of programs that are blocked from running. Then just select the programs that you want to allow to run and click "ok". When you uninstall the software, you will no longer have access to these programs so you can ensure that your computer is protected.
You can also use USB Firewall to check your emails. All emails, even the ones that you deleted, are still on your system. You can then choose to either delete those emails that you don't need anymore or to delete them all at once. Just go to "Settings" and select "Email" to see how many emails you still have. Once you have deleted all the emails you no longer need, you can then set the software to scan your PC and allow the programs that you do need back on your PC.
