unable to start correctly

[Elysium]

Hello friends here,

Today in my job had such problems:

troubling was to accessing on any programs on pc's no browsers, antiviruses, programs even not word, excel files was not accessable. when i were clicking on the file to open it was pop out something like that window: ,,the application was unable to start correctly (0x00000005)." Such like problem had 5 PC in same building.

What the hell is that?

Can any explain me what is it and what have to do?

thanks in advanced.

At first it sounds like a virus, or a system that was cleaned from a redirecting virus. What is the operating system on these computers? (this isn't the forum for technical discussion)
