Hi

No, this was a scam. Well done on spotting and stopping it, but I recommend you make sure you run a full anti-malware scan.

For further details, I recommend you have a read of I found a fake Firefox update.

. Whenever you get a message / popup that software / files need to be updated;

DO NOT USE ANY OF THE PROVIDED LINKS

While this may be a legitimate message, it could also be Malware or a Virus. Anytime you want or need to check for upgrades, go to the website of the True Owner of the program in question. For example, to check out Firefox, go to https://www.mozilla.org {web link}
