...well, just dont download random stuff from the internet and run it on your important machines then? :-))

You are right: 30 years ago, it was safe to go to vendor XY page and download his latest version and it was more or less waterproof. Today with all these mirror sites, very often better SEO ranking than the original, its quite dangerous: In my former bank we had a colleague who installed a browser add-in that he used for years (at home and in the bank); then he got a new notebook, fresh browser, he installed the same extension - but from a different source than the original vendor: unfortunately, this version contained malware and a big transaction was caught by compliance in the very last second, because he wasnt aware of data leakage.
