Remove the Tlerauic PUP

  • March 16, 2017

The Tlerauic PUP, or potentially unwanted program, is commonly installed along with adware and other unwanted programs when you download free programs off of the Internet. This program is delivered as two DLL files named obtorsub.dll and oviita.dll, which will be loaded by numerous running processes such as explorer.exe and chrome.exe (Google Chrome).

  • Chrome loading the Tlerauic DLLs

As this unknown DLL is injected into various processes and is commonly bundled with adware or other unwanted programs, I find it suspicious and would not want this program to run on my computer.

How was Tlerauic Installed on My Computer?

It is important to note that Tlerauic is bundled with and installed by free programs that did not adequately disclose that other software would be installed along with it. Therefore, it is important that you pay close attention to license agreements and installation screens when installing anything off of the Internet. If an installation screen offers you Custom or Advanced installation options, it is a good idea to select these as they will typically disclose what other 3rd party software will also be installed. Furthermore, If the license agreement or installation screens state that they are going to install a toolbar or other unwanted adware, it is advised that you immediately cancel the install and not use the free software.

If you have found the Tlerauic program installed on your computer without your knowledge or permission, then I feel that you should remove it from your computer. To remove this program for free, you can use the removal guide below.
