Standard variation on the "Windows Computer Security Problems" scam. Heavy East Indian accent. Auto-dialer bot generated. Do NOT speak to them, do NOT give them any information, under any circumstances. Key trademark signature: if you push them aggressively to identify themselves or give you the caller agent name, they either hang up rapidly or get foul-mouthed, abusive, and even threatening. Numerous reports about them, on multiple look-up services. These guys need to be shut down, hard.
