Kaspersky Lab Has Resolved Issue of Company Products Blocking Internet Access

Woburn, MA –February 5, 2013 – Kaspersky Lab has fixed the issue that was causing the Web Anti-Virus component in some products to block Internet access.  The error was caused by a database update that was released on Monday, February 4th, at 11:52 a.m., EST. 


The problem was limited to x86 systems with the following Kaspersky Lab products installed:

  • Kaspersky Anti-Virus for Windows Workstations 6.0.4 MP4
  • Kaspersky Endpoint Security 8 for Windows
  • Kaspersky Endpoint Security 10 for Windows
  • Kaspersky Internet Security 2012 and 2013
  • Kaspersky Pure 2.0


When these errors were reported, Kaspersky Lab identified an immediate workaround and recommended that customers experiencing problems disable their Web Anti-Virus or roll back the update to a previous version of the database.  At 5:31 p.m. the same day, the problem was fixed by a database update being uploaded to public servers.


Customers need to perform a database update to resolve the issue. If an affected machine updates from the Administration Kit/Security Center console, then these updates will be downloaded automatically. If a machine updates directly from our servers, then the initial workaround step of disabling the Web Anti-Virus component should be applied first. Internet connectivity will then be restored and the customer will be able to download the most recent database update.  The Web Anti-Virus component should be re-enabled after downloading the database update.

Kaspersky Lab would like to apologize for any inconvenience caused by this database update error. Actions have been taken to prevent such incidents from occurring in the future.
