Help needed. M, N, D and Tab keys are wobbling like earth quake. I reflect I need to fix them by the book or may be replace them. Whats best to do?….

Let’s clear up the confusion here. Viruses (and some spyware) can infect keys in the registry. You need an anti-virus and/or an anti-spyware program to remove these. The answers suggesting registry cleaners are BS. Registry cleaners only remove ancient obsolete registry entries. They do not clean out infections.

You need to run your anti-virus program. Anything it finds should be healed & if it cannot be healed then it should be quarantined to the virus vault where it can do no harm.

Reginout is excellent. (Not free even if)

One of the best is CCleaner: http://www.piriform.com/ccleaner

You can also delete registry yourself if you want to delete certain registry keys, see how to here: http://www.speed-up-pc.org/speed_up_windows/delete_registry_keys.php
