Who calls from this number, who? When you call back there is a dial tone.

Got this missed call an hour ago, looked up the number, and brought me to this site. Thank you!I experienced these type of scams in the past. They simply make up stuff about your Windows OS, with the basic info they somehow syphoned from your ISP or Internet activities. I told them off.

I got a call from (604) 678-5888 yesterday evening, and they could properly address my full name.  They said that my PC was infected with virus and needed to do something on it immediately by following their instructions.  I called Telus, my phone provider the next morning and they confirmed that my phone and internet were OK.  mkJul 24, 2013

Have recieved call from this number twice, and they hang up in 1 ring, if i call back .it appears to be a dead number.

I received a call from (604) 678-5888 from someone who sounded like a Chinese guy I could tell from his accent, told me he was a windows maintenance contact ,asked for me by my full name and asked if that was me, when I replied yes, he put the phone down immediately. I tried to call the number back straight away it was a dead number, how is that possible. I tried it several times, I am now worried in case somebody hacks into my system.

Who calls from this number and what do they want.

Nobody is going to hack into your computer, so don't worry.  It's a scam from India.Best rule to follow?  NEVER, EVER give anyone any kind of personal information out over the phone unless YOU were the one who initiated the call.
