i don't have java on my desktop, and i use firefox, chrome and IE. no issues, other than this forum hates firefox for some reason and won't let me preview posts.

also, java is not the same as javaSCRIPT. the only relation between the two is the word "java". if you turn off javaSCRIPT, expect sites to stop working.

In Chrome you disable JavaScript in settings > show advance > Pravacy [Content Settings] 

When you visit sites you trust right click an empty region on the page > View Page Info > Permission > Always Allow, for that site. 

You can also go to [Content Settings] and manage sites; insert url (links) to the sites you trust (often visit.)  

The concern about JavaScript is probably due to the development of easy to use software 'hack program/tools' that are becoming much more clever (very high threat to privacy, security), and my guess is that this ilegal program relies heavily on Javascript.  

IIRC reading an article by HLSecurity agent is that this threat (powerful hack tools/software) is a major concern. The developers regularly update the software (hack program tools) + adding new features. It can do a whole lot of very nasty things such as; lockdown your computer, hijacking, steal passwords, websites dns information and more. DNS hijacking is very serious especially if that site has retail along with customer information.

I was having probs on my laptop on allot of sites especially with Chrome

I uninstalled all instances of JAVA and everything is running great so far.
