002538020308 where does it come from?

It's from India and it's used by scammers. they will inform you there is a problem with your PC and that they will fix it for you remotely - of course you will be asked for your Credit Card or Bank details. Again, it's a scam, don't let them near your computer and do feel free to have some fun at their expense (e.g. irrespective of the question keep answering "Yes").
