What is jaucheck.exe? Is it a valid part of Java doing the same as jucheck.exe? I have searched for jaucheck.exe with Yahoo and Google but I can't find any relevant information. I know jucheck.exe very well, and for the few out there that does not know it, here is what WinPatrol has to say about it: I first encountered jaucheck.exe a few days ago when it asked the firewall to access the router, I had just updated Java. When I could not find any information on jaucheck.exe anywhere, I uninstalled Java yesterday and searched through the system for manually deleting everything that had to do with Java. Then I downloaded Java and installed it again. Now jaucheck.exe asks the firewall to access the router. The automated Java updater is not scheduled to update now. The path to jaucheck.exe is the same now as it was before: C:\Programfiler\Fellesfiler\Java\Java Update which is normal. In the same folder there are several exe files: jaucheck.exe jaureg.exe jucheck.exe jusched.exe All these files was created when I installed Java, and if they are virues then the java.com website must be infected.
