My colleagues system started to have problems such as very slow response to mouse events, clicking on control panel will take minutes to open the window etc. even though task manager shows no processor consumption.
Accidentally we found that kaspersky antivirus was installed and its license got expired. So we uninstalled kaspersky as we don't have fresh license to update it.
But then the system starts to behave very normally and quickly. It happened in another instance too. In internet also couple of forums discuss about this problem about a corrupted kaspersky installation that uses older versions dlls and makes things worse.
So remember when your Kaspersky runs actively, probably you may not have issues but when you see it got expired then either renew the license immediately or better uninstall it if you can't update the license immediately.
