What is deltaEng.dll? Should I remove it?
deltaEng.dll is a very fraudulent file that belongs to Montera Technologies LTD. This file looks like a typical .dll file but the beginning of its name should give you a chance to understand what virus is related to it. Please, do NOT leave deltaEng.dll on your computer because it has been found that it belongs to a seriously suspicious program, which is known as delta-homes.com.
It has been added to 'browser hijacker' and a 'potentially unwanted program' category for several reasons. The first of them is its distribution technique – Delta homes can easily infiltrate your computer without your approval because it has been actively promoted using bundling. It addition, security experts have also warned that this program can try to change computer's settings and drop its own add-on on each of web browsers, including Internet Explorer, Google Chrome, Mozilla Firefox, Safari, etc. Finally, it starts promoting third parties by showing altered search results that can be filled with questionable content, such as misleading links
Nevertheless, it seems that the appearance of deltaEng.dll can also show you that it is infected with Delta Toolbar, Babylon Toolbar, Montera toolbar and other malicious programs that can also try to initiate the same issues as delta-homes.com. It is located in the 'C:\Program Files' folder, so if you have just noticed it, you should remove it from the system ASAP.
