Dear Sir / Madam,

When I am trying to open .exj extension file, I am getting error as mentioned above. Please help me, whether I have to install any java module or something other has to be done.

Thanks

I googled your title and a lot of people have this problem when their machines are infected with malware. I would suggest this:

1. Download and run the (free version of) MalwareBytes (the blue button on the left of this page):

Malwarebytes.org (http://www.malwarebytes.org/)

2. Uninstall ALL version of Java that you have on your computer. There may be a lot of them. Simply go into Add/Remove programs, locate them, and uninstall them.

3. Reinstall the latest version of Java:

java.com: Java (http://www.java.com/en/)

Good luck
