Updating from Kaspersky 2010 to 2011 has created chaos on my Dell Inspiron 1520! I tried to use System Restore but that did not work as Windows could not close down. I cannot start in Safe or any other diagnostic mode - the start up stops after Sys32\Drivers\Mup.Sys is loaded. I eventually got the machine running after using a utility to identify all the broken Kaspersky links in registry (all referred to KIS 2010) - nothing else. I was then able to back up my data to an external drive. By this time System Restore had diappeared completely - nothing happens when it is called. Also for some reason I could not print emails from OE so had to paste into Word to print. Now after restart I still have no System Restore and the mouse/touchpad does not work. External mouse does not work either. Probably other things don't work too. I am reluctant to reinstall Windows and lose all my stuff (especially accumulated emails). Any suggestions how to recover mouse control and System Restore please?
You are probably going to have to do a repair install. You can do this and retain all of your files and software.

Comment of Lorraine:
If you have gotten your OS successfully repaired by now I would advise against re-installing Kaspersky 2011 until there has been more time to get the "bugs" worked out. Many people have had trouble similar to this forum discussion.http://forum.kaspersky.com/lofiversion/ ... 74096.html
It might be wise to stick with 2010 for now.
