Live Technician Sounds like a scam Internet

I had an almost identical experience with Live Technician except that I did not allow them to install software. Instead I have been called almost weekly with urgent calls from them notifying me that I must address this issue of someone hacking my account and allow them to help me - for a fee. According to them someone from Ontario is using my account to extort money from people and I could be implicated as a criminal if I don't cooperate with them. Sure sounds like a scam. The sad part of all of this is that it all started when I had an issue with GMail and when I googled support, their name popped up and I actually did allow them access to my computer to help fix the problem. BIG MISTAKE!
