Unidentified Program Wants Access: win1454180608.exe. Safe or not?

Ok, this happened before with a file called jucheck or jecheck or something but it was an exe file and wouldn't stop flashing in the task bar wanting me to allow it to do whatever. I read both that it was a java update and it was a virus so I just kept hitting cancel but it wouldn't go away until I restarted my computer. All has been fine for weeks but today I get this flashing message asking about Win1454180608.exe. I tried restarting and turning off the computer for a few minutes before turning it back on. It starts up asking about running some weird .tmp file which cancels fine but when I open FireFox (looks like v5) it wants this weird win file to run. I can't be sure cause I didn't write it down before but I think the number after win changed too.

 

One last bit: it says it can't verify the publisher which I find disturbing. Didn't think anything had downloaded that could be a virus but what do you guys think? Is this safe or not? I tried to get a print screen of it but it won't work for some reason. Thanks for your help anyone/everyone/whoever!

EDIT: Well crap, It popped up again when I was trying to change windows and I must have hit accept somehow. Guess I'll keep you posted if I notice anything weird but at least the annoying flashing box is gone from my task bar. Still though.......anyone know what this is/was?
