The file you just clicked on isn't actually a file but rather a link to a website, like google.com! Google has recently introduced a new 'TLD' called '.zip', which so happens to be a common file extensions, that's probably the reason you got tricked and ended up here!
FAQ:
Q: Did I actually get hacked?
A: No, this website has no malicious code, it's just this page alone!
Q: Did someone try to hack me?
A: Probably not! Some apps or services will automatically hyper-link anything that looks like a website, so it probably assumed 'sketches.zip' was a website
Q: How do I avoid this in the future?
A: Double, triple & quadruple check any hyperlinks (the blue text with an underline)! If you're not expecting to visit a website and the hyperlink has something like 'http://' or 'https://', it's probably not the file you want to download.
Q: What is 'TLD'
A: It's part of the Domain Name System (DNS), it's a very important part of the internet that converts IP addresses (E.G 192.168.1.0) to more friendly 'names' like 'google.com', the TLD is the '.com' part. You don't have to know this, just follow the tip above!
