Tech Support Scam

I received a phone call from a person with what sounded like an Indian (from India) accent. He told me my email had been compromised and my computer hacked. The caller wanted be to get on my computer so he could "fix" the problem. Since I have been a victim of a fraud scheme before, I was suspicious. I asked what his companies BBB rating was. He said three stars. This told me he was lying, and I hung up.
