This company put up an ad which appeared in area on my computer which led me to trust it. I know better, but paid for what looked like one issue, then I noticed a second payment pop up in a month, called and was told I had "subscribed" to their service.
Another persons report warned that they actually may install spyware. I would warn that this is a useless service, has misleading ad, and charges you indefinitely, so don't answer or respond to their ad.
