US-based Kaspersky customers have expressed concern after UltraAV software unexpectedly appeared on their devices due to a poorly managed transition process following a nationwide ban on Kaspersky antivirus solutions by the US Department of Commerce, effective in late September 2024. Kaspersky announced a partnership with UltraAV and a transition plan, but communication was unclear, leading to confusion among users. Some received emails about activating new accounts, while others did not. A software update rolled out on September 19 resulted in UltraAV being installed without user consent, causing suspicions of malware. UltraAV's FAQ indicated that the software is activated on Windows systems, while Mac, Android, and iOS users must download it manually. Users are considering canceling subscriptions and uninstalling UltraAV and UltraVPN due to trust issues. Rob Joyce, former NSA Director of Cybersecurity, warned about the risks of granting root-level access to software, emphasizing the need for caution in trusting such solutions.
