Your browser identified itself as a version of IE that was often shipped with default settings that were less than secure. Your internet experience could be made more secure by opening Internet Options in your browser, going to the Advanced tab and looking under the security settings for "Use TLS 1.1" and "Use TLS 1.2". Ensure these are turned on (checked). Doing so will enable your browser to support a higher quality of encryption on this and other websites. You will still be able to browse this site without turning on support for TLS 1.1 and 1.2, but we will have to use a lower level of encryption to accomodate you. See this question on Stack Exchange's Superuser forum from 2011 for more details keeping in mind the comments about TLS 1.2 non-support were made many years ago, and things have changed since then.

If the support for better cryptography has been turned on for your browser, thank you, and you can safely ignore this advisory.

PKZIP for Windows Desktop

File Compression Software

PKZIP continues to be the gold standard in data compression and file management, evolving as your needs have changed. PKZIP compresses and extracts files to greatly reduce required storage space and transmission times. And, by using the .ZIP standard, the most widely used file standard in the world, you can easily exchange data across all major computing platforms more efficiently and effectively.

Simply drag-and-drop files into the PKZIP interface to compress files.

PKZIP in Action

Built on the familiar and reliable .ZIP standard, SecureZIP is the only data-centric security product that allows you to encrypt information on one computing platform and transfer it to any other computing platform in your environment. Learn more about SecureZIP
