Error (by 2 users)

Both of you need to do a virus scan. I prefer avast.com home edition. It is free and very powerful as well as easy to use. Then get ahold of an anti spyware program Webroot is an option. I prefer spybot search and destroy. It is also free. In that path I see "mywebs~1\bar" ... that is bad. Mywebsearch is spyware. Get rid of it.

Now, this error you are seeing may be from an anti-spyware or antivirus program already removing it but leaving the registry entry in tact. Simply run regedit and search for mp3plugin.dll and remove any instance of it in the registry. This should take care of your problem.
