Kaspersky 2010 Slowing Windows Explorer
If you have installed Kaspersky 2010 and you find that your Windows Explorer is running super slow, the cause is Kaspersky and you will have to do a repair.
Go the Start, click on All Programs, scroll to find your Kaspersky program, click on it and then click on “Modify, Repair or Remove”. Once it is started, click on the middle icon title “Repair”.
Once this is complete (it could take some time to complete), reboot your PC and the speed problem should be gone.
