Re the above post: DO NOT use msconfig to make permanent changes to startup processes. Use a dedicated app such as Mike Lin's Startup Control Panel for apps and services.msc for changes to services. MSCONFIG was designed to be a diagnostic utility and should only be used as such.
Additionally, the fact that Revo doesn't find it at first does not mean it won't find portions to delete in "hunter" mode.
Last, NEVER - NEVER - NEVER use a registry cleaner. They CAUSE problems, the do not cure them.
