Hello.
Remember the story when
Avast completely blocked the network ? So this time Kaspersky distinguished himself. Or rather, Kaspersky Anti-Virus 6.0 for Windows Workstations. Because of the update, which was released on October 25, KAV blocked the tcpip file on Windows 7 32bit.
The solution to this problem is to launch the fix, from the Kaspersky Lab itself.
The administration of the company has already
apologized and released
an article with the correction of this bug.
