Chill

I know but there a lot of experts visiting this forum every now & then. I am sure someone would be interested to make this idea come true. I am hoping for a positive response.

I was wondering if it is possible to make a payload that upon execution would hide in a system and silently search for particular files on a PC according to any given criteria (such as name of file) while making sure that the system usage keeps well below 20 or 30% so that the user may not know whats happening and upon retrival would delete those files permanantly.??????????????????????????????????? Any IDEAS??????????????????????
