I have purchased a laptop of Samsung since few weeks ago and I have connected an internet service provider of MTNL the MTNL is the leading internet service provider in Mumbai. I think so that it provides up to 4 Mbps of speed. And I think this is the fastest speed that I ever have. But recently there is a problem with the laptop or I think so with the network I am using. The problem is with the Gmail that all my contact lists of all addresses are receiving spam emails from my Gmail account. I think that this happened 2 to 3 days ago and now I am thinking that how is this happened because I remember that 2 to3 days ago I was not in Mumbai I was in Goa enjoying weekends with my friend. So can anybody help me in solving this problem?
