Who called from 5205007205

Called through my solicitation blocker - only to hear dead air.  Telemarketers are alive and well,.

message left   alert system scam

Got a call from this number 7/18. No valid CID name. Google search showed nothing here yet. Other seach hits showed people and business. I clicked on one that had a kind of google logo. My PC instantly picked up a Trojan virus. Support scam:JS/techbrolo.f
This is a well know very active Trojan. Locks browser and asks to call a number to fix computer.
Pulled network cable and rebooted. Virus software took care of it on a scan.

Just got a call.  Did not answer it said  ID said Tucson AZ .  No message left.
