I have a client who tried updating Kaspersky and was unsuccessful.  When we boot into windows the keyboard or trackpad does not work.  Its not a hardware issue because i can choose safe mode, tried USB keyboard and booted into ubuntu and the keyboard and mouse worked fine.  I tried removing all Kaspersky files and it did not help.  I would think its in the registry and would check there but i cant get to it because I cant type anything in to get past the password.  I also took the drive out and scanned for viruses and it came up clean.

Any Ideas?

Did you try to start the system in safe mode to check if it works?

You can also try a System restore:

I also took the drive out and scanned for viruses and it came up clean.
Note this is not the proper way to scan for Malware.

Does your On Line Keyboard work so you can try some of the suggestions?
Start|type osk|click osk.exe

I can't even type the password to login. When I book to safe mode I still can't use the keyboard or mouse. Even when I try and do command prompt.

I am a little confused.  In your original post you say you can boot to safe mode and use the USB keyboard.   You then should be able to login.

jcimarron- I can boot into safe mode but that does not allow me to use the keyboard.  I can boot in ubuntu and the keyboard works along with the mouse.  Thats how I know its not a hardware issue.  As soon as windows boots the keyboard and mouse does not work.

joinaunion- I reset the bios to factory default and no luck.  It is a dell XPS L502x.

I would still try another keyboard and see if it makes a difference.

So I was able to find a restore point.  Got the keyboard working and kaspersky removed.  Now its really weird. The key board stopped working and in regular mode.  Do a system restore when the keyboard is working  and it does not work in normal mode when it boots and if I restart it in safe mode the keyboard still does not work.  When I do the system restore and go straight to safe mode and the keyboard will work.  When i boot into normal mode the keyboard will not work in either normal or safe and have to do a system restore and boot right into safe mode for it to work.

Have you tried Booting from your Win 7 installation disk?  If you can get into Windows, that would allow you to run a Repair Install.

Your personal data and installed programs should not be affected but a backup is always a good idea.

Did you ever try the Online Keyboard?
Start|type osk|click osk.exe

I will try the windows repair. When the keyboard doesn't work neither does the mouse. It's weird.
