I often visit it when I want to view some video-clips
What you need is make sure your malware protection tools is running and always up-to-date so it will catch any virus or malware on files or pages that you will view or click.
If you have Youtube account and have receive unknown private messages to click/view on videos, do not simply view it. There are reports of such virus/malware via private messaging and even "spam" comments in Youtube that will serve malware.
I have WOT and Link Scanner Pro installed so when I do a search it and they both show green the website is suppose to be SAFE.
What is the best way to tell if a website is SAFE????
Both programs show YouTube as being SAFE but I was told that
you can get virus's there.
