Why Are My Videos So Slow Why Are Videos On Youtube Loading Slow For Me?

Why are videos on youtube loading slow for me? - why are my videos so slow

Ok so when I visit YouTube videos take some time to load and do not take a buffer, some videos, the time and all the others take a real long cargo. My team has scanned for viruses and my drive is free from trojans, but the videos seem to be a problem. Why is this so?
