Is prxtbelf0.dll safe or is this malware?

Purpose of prxtbelf0.dll:

prxtbelf0.dll file purpose and description:

prxtbElf0.dll is a program which could have been installed by you, or may have even arrived on your computer the day you purchased it as this may have been preinstalled software. The actual disk location is also listed below, always verify where its located on your hard drive, as this makes sure it is not spyware or adware simply placed elsewhere on your computer, and using the same name in an attempt to fool you. This file is a DLL file (always view the proper file location shown below, as many spyware files try to imitate other programs), and it adds features like search to your web browser toolbar at the top. This prxtbElf0.dll file is part of the Elf toolbar and may include other BHO's with it that run in Internet Explorer. There has been system instability or crashes reported related to this toolbar. Yes, I would personally remove this if it was on my computer even if it was considered safe. (See the details below for the actual location of this file.)

General information:
Be aware that many tasks will be similiar names to existing tasks or processes. You can always view the running tasks on your computer by pressing ctrl-alt-del to view the windows "task manager", and then view the "processes" tab. This will show you all tasks running or currently active on your PC. Although this shows you all running tasks, it does not show dll file thats are loaded, as they get loaded as part of other processes. Many spyware writers attempt to hide their files on your computer, for example, prxtbelf0.dll may be intentionally misspelled to look like a similiar task, or spyware may be named very similiar to a Windows system task. The reason they do this is so you cannot easily recognize the name in your tasklist as I have mentioned above. Make sure always check the location of the file if you are concerned. You can always find the location of prxtbelf0.dll on your computer by using your Windows search options, but I will also try to list the file location of every file described on this website, so you can verify the correct location.
