Received a call from this number stating my vehicle warranty was running out. I asked the "lady" where she was located and she said, "your house" and hung up. I guess I'll just keep blocking their numbers each time they call.
Just got this missed call. It appears if you have WebPlugins enabled they take the number on the website and call it to try to sell you something or scam you..
I suspect:
"Flash Video Downloader"
and/or
"Canvas Defender"
on Firefox are the spyware culprits.
