Using YouTube can be hazardous to your computer.
The majority of the above-supplied links either result in a "404 Not Found" link (YouTube Targeted By Malware Writers), the link doesn't take you to the specified article (Malicious videos open dangerous attack vector....), the site cannot be reached due to "ERR_CONNECTION_TIMED_OUT" (Fake YouTube Pages Infect Users With Malware), or the information discussed is 3,4,7 or even more than 10 years old and generally refers to vulnerabilities that are specific only to unpatched operating systems.
And then there's this:
I downloaded Youtube videos, but found out just now it is illegal. I thought that if Mozilla page has add-on for that, it must be legal!
Could Youtube videos be infected? Could Youtube infect them to punish illegal downloading? I removed the add-on - should I delete those videos too to be safe?
If I use AVAST, Emsisoft Anti-Malware, Malwarebytes and SuperAntispyware Free Edition, will I be safe and find anything there is?
I'll never download anything from Youtube ever again!
YES! Delete the videos..
YT is NOT punishing downloaders by purposely infecting videos.
Downloading copyrighted material on the YT website is contrary to the ToS, but the Download Police are NOT going to come knocking on your door and arrest you.
Personally, I have yet to come across any proof that YT videos are themselves being infected with malware. Ads and browser add-ons can be a source of infection.
