Can you get a virus from RuneScape

RuneScape doesn't give you any viruses; but it does install cache memory onto your computer to make it (RuneScape) run faster. This may slow down your computer's overall performance, since it takes up RAM and space. It is a browser based game and to get a virus you need to download the particular file, and you do not need to download anything for runescape (unless it's Java which you need to play it).Though you can download runescape client (optional have to do it manually) someone could put a virus on that other then that not possible.

EDIT: to answer the question straight forward: no. I've checked with norton safe websites and its fine. no viruses, nothing.
There are no viruses on Runescape. I have played for 5-6 years and i have gotten nothing. only viruses you can get is if you try to cheat by downloading an auto client or something. and something else you can consider a virus is being addicted to runescape :) and makeing runescape your life.
