- Annoying Pop-up's
Have you recently installed Music Toolbar on your computer? Have you then deleted the application? If so, there is a high possibility that each time you open your web browser you are being displaying this apcrtldr.dll pop-up notification:
The access is denied because the apcrtldr.dll file no longer exists on your computer. You must have removed it along with Music Toolbar. However, it shows that even if this browser extension can be uninstalled via Control Panel, manual removal is not fully effective. Some of the toolbar’s components must have remained on your system and as a result, they try to run apcrtldr.dll and each time they fail, you see the pop-up.
Music Toolbar is actually a potentially unwanted program that enters computer system together with other freeware applications such as Shareaza player. Users seldom notice that they install additional freeware on their computers, because most of the time, they skip important installation steps. Hence, if you end up installing the full version of Music Toolbar setup, you will even get your default home page and search engine changed. The next time you open your web browser, you will automatically redirected to search.ask.com.
Thus, if you have noticed how annoying and potentially harmful Music Toolbar is, you must have opened Control Panel and removed it manually. However, in some cases, not everything related to potentially unwanted programs gets deleted and what remains is an “orphaned registry entry”. It means that the entry which his supposed to run the program automatically is there, but there are no longer any files that would allow for the program to function. Hence, each time the entry tries to load Music Toolbar; you see the apcrtldr.dll error message appear.
To make the apcrtldr.dll disappear you need to remove the registry entry responsible for running the command. If you are not an experienced computer user it would not be a good idea to open Registry Editor and try removing the entry on your own. In such a case, you should scan your system with SpyHunter free scanner, because there are bound to be other leftover files remaining on your computer. When all the random files are detected, you should acquire a reliable computer safety application that would terminate apcrtldr.dll and all the other unwanted applications or files from your system immediately.
Keep in mind, that investing in a licensed computer security tool also protects your PC from various malware threats that might come barging in the future.
