I checked the topic in <removed by poster>, out of curiousity. Below is what I read. That never crossed my mind that viruses can spread that way. So I have two suggestions.
1) In options, a checkbox to "Strip codes when message contains an URL"
2) In options, a checkbox that would display this warning when appropiate: The URL you have clicked on contains codes inside of it. The full path of the URL is <stripped URL>, do you wish to continue?
<removed by poster> 1if you got a msg from a user that look like this: http://www.domain.com/hotpic.jpg0
,0.exe 1 make sure you first hightlight it befor you click on it, so many users got infected with viru's that way. || http://firstname.lastname@example.org
