Live Technician is a fraud company. Do not hire services of Live Technician. They will tell you that your system has been hacked and will ask you to give $200. So do not believe on them. They are fooling people of USA, Canada, Europe and making money.
Its a bigtime scam that these companies are doing. I, myself, have been a victim of these fraudsters. Do write a complaint to FTC using this link:

I have come to know that, they are operating from India with their centers in Noida, Jaipur, Mohali and Dehradoon and robbing off people with more than $1.5 mn every month. Their websites are - www.livetechnician.com and www.onlineresolve.com and many others. They simply send 100% FAKE/forced POP UPs to customer's computers and charge a handsome money saying that its a virus. The company is registered as Live Technician Technical Solutions Pvt. Ltd. with its registered office in New Delhi and the CEO's name is Samay Vashisht.
