Is it a virus ???

I have encountered this strange problem...
I have developed a JSP page (its size about 6 kb) ok..
after some days, I need to modify it, when viewing it, it was about 40 kb!!!
I opened the file and saw a very long VB script (it was located after my </html> tag)
this script was containing a very strange symbols...
I shocked when seeing the same script in my all html pages (these pages were saved from the web)!!
is it a virus ? or the Java plug in posted this script to enable the plugin??

satish,
JavaRanch is a community of people from all over the world, many of who are not native English speakers. While using abbreviations like "u" instead of spelling out "you" is convenient when text messaging your friends on a cell phone or in a chat room, it presents an extra challenge to those that are already struggling with English. Additionally, such shortcuts may confound automated translation tools that patrons of the Ranch may be making use of.
I would like to ask for your help in making the content of JavaRanch a little easier to read for everybody that visits here by not using such abbreviations.
thanks,

ohh, please tell me, what this virus do ??

You might be better looking on Symantec or McAfee's security response sites to find out more. Since you don't give us a virus name, only one (of possibly many) of its symptoms it is a little hard to second guess what it might be. Installing proper virus scanning software and running a full system scan is a good way to start dealing with the problem.
