An anonymous reader writes "Antivirus maker Avast is suspending its relationship with iYogi, a company it has relied upon for the past two years to provide live customer support for its products. The move comes just one day after an investigation into iYogi showed the company was using the relationship to push expensive and unnecessary support contracts onto Avast users. In a blog post, Avast's CEO wrote, 'We had initial reports of this behavior a few weeks ago and met with iYogi's senior executives to ensure the behavior was being corrected. Thus, we were shocked to find out about Mr. Krebs' experience. As a consequence, we have removed the iYogi support service from our website and shortly it will be removed from our products.'"
