Called from the (213) 271-1645 but wanted me to call back on the (857) 999-0945 to order their software to repair my computer. I noticed today that it was running slow etc. and it's only 2 mos old and I'm not sure if they are related but a couple of days before this call, my cell phone company suspended my service due to fraudulent international calls. They said the caller hacked into my computer while I was updating my online account. I even asked "Jack Wilson" (with a thick accent if these problems could be related to that of course he assured me they were not related. After he took control of my monitor from his computer my wall paper went black. After hanging up I noticed a small icon that was A and was red and white I stopped that and my wallpaper came back. A couple of minutes later my screen flashed and the icon was gone.
