bored computer noob with an idea. is it even remotely possible

[Reaper 392]

i have heard of several people getting an indian guy saying that they are part of windows and have detected a virus on your computer that they have to remove manually or something. then, if you are very dim, you give whatever details you need to allow them access to your computer.

what i was wondering is, would there be a way of getting back at them and controlling their computer, or doing something irritating to their computer once they were 'inside' yours, or is that really not going to happen?

if not i'll just play dumb with them for 1/2 an hour, or do the 'you've called up a murder scene' prank on them or something when i do eventually get the famous call

ok, so it sounds like a super complicated thing to do. i was hoping it might be a case of 'a door, once opened, can be walked through in either direction.' didnt really have any specific ideas of what i would do once i was in the computer, but i would have put my mind to it if it was easy

guess that if i do get this call i will just go for the 'you called a murder scene' prank or something
