SHA-1 & SHA-2 are algorithms a certificate uses to sign binaries, and Quick Heal also signs its binaries in the products. Quick Heal has been using dual (SHA-1 & SHA-2) code-signing for its products.
According to an announcement, Microsoft will no longer allow certificate providers to issue SHA-1 supported certificates. The SHA-1 hashing algorithm used for code-signing of Quick Heal products will expire on June 4, 2021, and we will use new credentials that only support the SHA-2 algorithm.
All new software packages, hotfixes, or security patches of Quick Heal products created after June 4 2021 will use only SHA-2 Certificate for code-signing.

How to check if the required MS Patch is already installed or not?
We recommend using the latest version of operating systems to avoid the risk of exploits targeting vulnerabilities of the operating system. Windows operating systems that Microsoft no longer supports can be potentially vulnerable as Security patches/updates are not released for this operating system by Microsoft.
