Question

I keep getting phone calls from strange numbers such as quotquot.. who the heck is this?!?
I answered it once like a month or two ago I dont remember what happened if it was automated or nothing, but it happened again today and i answered and hung up really fast. Ive heard cell phones can catch viruses now, and im just hoping thats not what it is..

Answer

A computer calling automatically.brEither a recorded message kicks in,bror if you answer too late,a hangup.
