Antivirus programs are software tools which scan through your PC and remove any of the viruses or malware infections that are on your system. It’s often the case that viruses will infect various DLL files on your computer and then cause them to be unreadable to your PC. To ensure this is not happening on your computer, you should try using an antivirus program to scan through your system and remove any of the infections that cause all these errors. You can download our recommended antivirus program from the link above, but there are a large variety of programs available.

Step 5 – Clean The Registry

Download This Registry Cleaner

The ‘registry’ is a big database inside Windows which keeps a large list of references for the DLL files on your system. This central database is where Windows keeps a list of the DLL file locations for your computer, and is where your system looks each time it wants to use a dll file such as xul.dll. Unfortunately, it’s prone to becoming damaged and corrupted and is constantly being unable to read the files and references that it needs to open the files that it wants. This is a major problem that causes a lot of damage to many different parts of your system. Running a registry scan will remove all the damaged references inside the registry, allowing it to run as quickly and smoothly as possible.
