Steckler cited an investigation by Brian Krebs of , a blog about cybercrime and security issues. To check out the iYogi service, Krebs called the support number on Avast's website to ask if his fresh install of Avast was updating properly. An iYogi technician took remote control of Krebs's system and installed iYogi's tune-up tool, PCDiagnostics. The tool reported that Kreb's brand-new installation of Windows XP scored only 73 percent (an indication of trouble), that the Registry contained errors, and that traces of old antivirus software remained on his system and were causing problems. (The test system, a virtual machine that Krebs had set up for the investigation, had no other antivirus software.)

The iYogi rep offered to transfer Krebs to another technician who could fix the issues if Krebs paid at least $170 for an iYogi subscription.

We contacted iYogi for comment. iYogi "maintain[s] a customer satisfaction (CSAT) score in the 90's range," a spokesperson for the company wrote. "A CSAT rating in the 90's range is amongst the highest in the industry, audited by KPMG. We take service complaints extremely seriously and address them with customers in order to help us improve and alleviate flaws."
