This is one of the most insidious pieces of malware I have ever come accross.
If you simply delete the ave.exe file you will lose all associations for all programs and not be able to run anything
It is a root kit virus "Rouge Antivirus" that pops up stern warning about how your machine is a seething pit of viruses and spyware. It is of course bull **** and just trying to scare you into buying their 'protection'.
It looks very 'offical' and very much like a windows operating system warning.
I'm running malwarebytes on the afflicted machine right now but I will probably have to go do some manual registry edits.
