Issues with Java

So this issue started last night because of a virus and it completly fked up my computer, so i managed to remove it. anyways ever since then Ive had trouble loading runescape because theres something wrong with java ive also tried deleting/re-installing it and with different versions but every time i start the computer i have to delete the java and download it again to load runescape

 

System restore.

 

System restore is a good idea.

Might also want to try adwcleaner or ccleaner after deleting java.

 

I had some bad issues too, I needed like 2 hours to load runescape again and im not sure why. Java had huge errors.
