A few days ago, a pop-up from a Java update (jucheck.exe) began to pop up on my laptop. It now pops up every day. It has never popped up before, so I immediately did a Google search and ran MalwayreBytes. MB did not find anything. People are divided on jucheck - some say it's a virus and some say it's a legitimate Java update. This says, "Added by the W32.Scrimge.O worm. W32.Scrimge.O is a worm that spreads through Microsoft instant messaging clients and opens a back door on the compromised computer."
On my laptop, jucheck.exe is located in C:\Program Files (x86)\Common Files\Java\Java Update... it says it was last modified January 17, 2012, yet I have never seen it until two days ago. Nothing happens when I press "no" when it asks to modify my computer.
What should I do? Should I delete it? Why wouldn't MB find it? Do I follow the instructions on this page?
