After the installation of a Kaspersky Lab product, Windows operating system may stop responding or return a stop error while the computer is being started or when some task is being executed. It might be caused by incompatibility of software or drivers installed on your computer with the chosen Kaspersky Lab product. If you encounter an issue of this type, send a request to Kaspersky Lab Technical Support with a Get System Info report file.
Please note: if the technical engineer didn't specify the type of the report, you should get a standard report.
Run Get System Info from the command line with one of the following parameters:
Sometimes Kaspersky Lab support engineers ask customers to send screenshots (for example, with the error or product settings window) so that they can solve the customers' issues.

The Temp directory is a folder used to store temporary files. When a program ends, the temporary files are deleted. However, sometimes these files are not deleted, for example, when a program is exited improperly. Cleaning, or deleting, the contents of the Temp directory frees up space on your hard disk.
In order to delete all files from the Temp directory and to free up space on the hard drive, perform the following actions:

In rare cases, installation or removal of a Kaspersky Lab product can be interrupted, which causes incomplete installation or removal. This can result in incorrect functioning of the keyboard or the mouse after the computer restarts; please allow a couple of minutes for the problem to disappear.
If the error remains, restart your computer again.
If it did not help, use the instruction below to eliminate the problem.
If you do not have a product CD, you can use another computer to download the Kaspersky Rescue Disk from our website and put it on a burnable CD or USB Flash Drive. Not all systems can boot off of USB Flash Drives, particularly older computers.
After the disks are mounted (made accessible), the Kaspersky Rescue Disk scan program will open. Here you should see drive letters for each hard disk in the computer. By default, C: is your primary drive.
If you do not see any drive letters listed, it is possible the Kaspersky Rescue Disk does not recognize your hard disk controller. Although the Rescue Disk is updated regularly, not all computer component makers provide the drivers needed. You will need to use a Windows System Repair Disc created on the same version of Windows as the affected system.
Technical Note: The KL drivers listed may differ depending on the product.
Editing the Registry incorrectly can lead to unrecoverable system problems. Proceed carefully.
There are many UpperFilters, but first one does not contain a Kaspersky entry. Looking for ones that start with KL. The two files are klmouflt and klkbdflt.
We are keen gather data from affected systems for our developers to analyze to prevent this problem from happening in the future.
