Customers of Kaspersky antivirus in the United States received an automatic update to a new software called UltraAV without prior knowledge or consent.
Some customers expressed frustration at the forced replacement of their cybersecurity software.
The transition to UltraAV comes after the US government banned sales of Kaspersky software.
Kaspersky confirmed the transition and stated it partnered with UltraAV to ensure a seamless transition.
