We have about 10 machines not booting this morning, The thing common to them is that they have KIS 2015 installed. They all freeze at logon with a black screen and a mouse pointer. The only solution is to boot into safe mode and uncheck the option to load it at boot, and then the machines boot fine. Thought I would post in case anyone else was having issues and had not yet identified it.
Got two here with KIS 2015, and they are booting correctly. Nothing about it posted on Kaspersky forums yet. Hope you get it sorted.
Thanks for the headsup. Other than Kaspersky 2015, what other common security software you have on all these 10 computers? I have 3 computers with KIS 2015 installed, no problems so far.
Yes, I have considered it is a combination with something else as I see nothing on their forums either. They are all Windows 7 x64 with KIS 2015, and Office 2010. They all have the latest Adobe Flash and Adobe Reader. The latest Firefox. I can't think of too many other common things. They are unfortunately a mix of different brands and hardware, so no common graphics drivers or anything like that. They would hang on a black screen with a mouse pointer either before or after logon. A forced reboot would bring it back to the same place. I booted into safe mode and from there was able to launch KIS and stop it from launching at startup by unchecking that option. Then we rebooted into normal Windows and and it fixed the issue with every single machine. KIS may not be the only factor, but it definitely is one.
This may sound a bit strange but have you considered uninstalling and reinstalling KIS on one of them and see what happens, or are they all networked?
I may reinstall on one of the machines for a test. Strangely I had 2 machines that booted up fine this morning. We are trying to determine what is different. The GSI log contains too much information for my taste. I guess I can run it myself and look at the results. The GSI log didn't show me anything interesting. What I did find was in the Windows event logs on all of the machines that would not boot the was an error logged with event id 7011. The error was "A timeout (30000 milliseconds) was reached while waiting for a transaction response from the AVP15.0.1 service." This was logged multiple times on some machines. Odd that I am not seeing anyone else with this issue.
