Interesting discovery: Panda Cloud doesn't need to update.

If you read this article: Panda Cloud Antivirus: Installation, you would know that I am using Panda Cloud Antivirus on my computer at the moment. Silly me, but it took me several weeks to discover an interesting aspect of the program. Panda Cloud doesn't need to update its signatures. I didn't see it update, but didn't think too much at the time.

Upon checking this matter up, I learned that Panda Cloud doesn't need to be updated.

Thanks to this special cloud structure, Panda Cloud Antivirus doesn't have to be manually updated. Thanks to this special cloud structure, Panda Cloud Antivirus doesn't have to be manually updated. Forget about complicated configurations and having to download new signature files! This doesn't mean you remain unprotected when disconnected from the network: Panda Cloud Antivirus features a local cache that keeps the program up and running, working at 100%.(Bolded for emphasis)
