Is xpcom.dll safe, or is it a virus or malware?
The answer is no, in itself, xpcom.dll should not damage your computer.
Unlike executable programs, such as those with the EXE extension, DLL files cannot be executed directly, but must be called by another code that is already executed. However, DLLs have the same format as EXEs and some can even use the .EXE extension. While most dynamic link libraries end with the .DLL extension, others can use.OCX, .CPL or .DRV.
DLL files are useful because they allow a program to separate its different components into individual modules, which can then be added or deleted to include or exclude certain features. If the software works this way with DLLs, the program can use less memory because it does not need to load everything at the same time.
On the other hand, if the .dll file is attached to an executable that is intended to damage your computer, it is possible that it is dangerous. We recommend you run a scan of your system with a tool like this that can help identify any issues that may exist.
That's why normally when you see a new .dll file on your computer, there will be an .exe file somewhere.
Make sure you scan both together so you don't have to worry about your computer being infected with something bad.
Can I remove or delete xpcom.dll?
According to various sources online, 1% of people remove this file, so it may be harmless, but it is recommended that you check the trustworthiness of this executable yourself to determine if it is safe or a virus.
Software programs store DLL files in one or more folders during installation. These files contain code that explains the operation to the programs.
If you are considering deleting xpcom.dll, it is probably best to leave it alone. The reason for this logic is that some programs share these files, so deleting a particular DLL file can unintentionally cause problems. This means that deleting xpcom.dll may cause one or more other programs to stop working, or only to a limited extent.
Some software can also install DLL files in several folders outside the Program Files folder (where most programs are installed). Finding these DLL files can be very difficult, and deleting them can be dangerous.
As mentioned above, if you are not sure if xpcom.dll is being used by another program, we recommend that you leave it alone. However, if you need to delete the file, we recommend that you first make a copy. If you then have a problem with another program that requires you to use the recently deleted DLL file, you can restore the file from the backup.
