    Be very careful how you respond to these criminals. If you scan and remove trojans or other files they have placed (even after they have gotten money from you), they will call you back and say "We're refunding your money. Let us have access to your computer again and we'll remove all the files we placed there."

    If you do so, they will delay your shutting down the computer by asking more questions while they install a PC Black Screen program that locks your computer and blacks out the screen to prevent you from accessing anything such as anti-virus pgms to scan. They know you are on to them and will then proceed to re-format your C: drive.

    Once you have been attacked by this bunch, call your credit card company to alert them of the fraud, uninstall the control program (something like TeamViewer) and scan the entire computer with SpyBot in the Adm Mode.

    another scam phone # 1-844-920-5222- has popped up 3 times in the last 6 months while online banking, researching health/nutrition/educational ideas for work and looking for recipes.

    Would expect some scams if searching for naughty stuff, but I'm not. Hate scams and know they are hurting vulnerable people.
