Dude... Might wanna lay off the crack for a while before that extreme paranoia gets the best of you...
To the OP:
Just go into the login properties of the service you are trying to start and select "This Account". Browse your computer and find the "Local Service" account. Wipe out the password so that it is blank and apply. You will be presented with a dialog stating the that the account has been granted the login as a service right. Then start your service. That should fix your problem. I have seen this issue countless times and there are many, many reasons why it could have happened but it's nothing to worry about.
