This is a scam call! An Indian male voice told me that each time I connected to the internet over the last couple of days, someone had tried to perform an unauthorized action. Wanted me to go and check my internet. I told him no, I would not be doing that, that I am quite happy with the security on my internet account and that I believed his call to be a scam. When I told him that I have the number he was calling from and I would be reporting it to the appropriate authorities, he hung up!
