Caller: "Microsoft Support" scammers with Indian accents

I received a call from a scammer with an Indian accent, who purported to locate a most terrible problem with my computer network. It was a "Trojan Horse" which had the potential to affect every computer on my network, but that he could fix the problem, if we paid him money. Of course, I terminated the conversation. Later investigations, using Virus Scanning software failed to locate any "Trojan Horses" or any other problems.

Caller: SCAM!!!!

Said my PayPal account locked due to unusual activities. I need to purchase a virus software to unlock the account.
The caller was also a bit rude, I found a bit odd at the beginning.

Caller: Microsoft

They are scamming. They said that my computer has zombie virus and asking for $1000to fix it.
