I am using ntl Netguard. Can I use PCguard?
Yes. You just need to uninstall Netguard, download PCguard, and follow the on-screen instructions. PCguard is the same basic software as Netguard and works exactly the same, but it just looks slightly different, so you should easily be able to get used to the new packaging. It has additional features like Identity Theft Protection, and it has also been updated to reduce known support issues and improve your security.
