Thanks for the discussion here. I’m a member of Kaspersky’s technical support team and wanted to jump in to provide additional insight on what we’ve done to provide a fix. I also want to express sincere apologies, on behalf of the entire company, for any inconvenience caused.

As you know, a threat signature update was released yesterday (Dec. 13th) which led to system instabilities and, in some rare instances, to system failure on a limited number of computers with Kaspersky Anti-Virus 7.0, Kaspersky Internet Security 7.0, Kaspersky Anti-Virus for Windows Workstations, and Fileservers v6.0 MP2 and v6.0 MP3. We detected the error within 15 minutes, and worked hard to minimize any effect by issuing a manual fix within 45 minutes and an automated fix 2 hours later. We realize this type of error is frustrating and hope that we eliminated all inconvenience with our immediate response.

For the future, our QA department has completed a thorough forensic review of our release process and added a new set of preventive measures to ensure that this type of problem will not happen in the future. Your system’s security is our #1 priority and we will continue to endeavor to provide the highest level of protection with our standard minimal system impact updates.

Again, we sincerely regret any inconvenience this has caused.
