Litigation

On February 27, 2012, a class action lawsuit was filed against Support.com and AOL, claiming that their Computer Checkup software would offer to perform a free scan, purposely find problems that did not actually exist and then offer to sell software to remedy those problems. Both AOL and Support.com settled the claim on May 30, 2013, by offering a refund to consumers up to a total amount of $8.5 million.

In December 2016, a complaint was filed against Support.com and Office Depot alleging their free PC Health Check Program used by Office Depot purposely misidentified malware symptoms, and that consumers were then encouraged to purchase repair services. In March 2019, Office Depot agreed to pay $25 million and Support.com agreed to pay $10 million to settle the complaint. Support.com suspended use of the PC Health Check Program in 2016.
