Hello there Meena
Although this strictly isn't the forum for this sort of thing, I am able to redirect you to infomation that i'm almost certain will resolve the problem for you. Please read the selfhelp instructions which can be found here
. Please use those instructions as a guide to removing Vundo from your computer. If you are not happy doing it by yourself and would like 1 to 1 help, or cannot remove the program using the self-help guide please reply and we can consider the options possible.
Welcome to BleepningComputer by the way.
