IMPORTANT! Dear reader, if you are reading this you are probably fed up with the annoyance that can be TerminusSys and want it removed immediately. This article’s removal guide will help you accomplish that, but it is also a good idea to not skip right to it. Learning how TerminusSys works and how it got into your system in the first place will aid you protect against other threats in the future.

TerminusSys – a simple overview

TerminusSys belongs to the Adware family of viruses. The name essentially explains what it does – it generates unwanted spam messages in the form of advertisements. Besides the usual offers for best deals you may also be seeing:

  • Warning to download updates to programs
  • Not being able to view something unless you download and install a certain video player
  • Error messages about missing plug-ins

REMEMBER! All of these offers gravitate between 3 goals:

  1. Waste your time and generate views for someone
  2. Entice you into spending money
  3. Install malware on your computer

Needless to say avoid interacting with stuff that comes out of TerminusSys. You are not losing anything – everything is completely fake and actually created on your own computer, tailored to your interests which TerminusSys analyzed from your browser’s history. Creating the Ads adds an extra burden on your CPU as well – if your PC has been performing poorly lately TerminusSys is a likely cause.


Next, lets explain how your PC ended up with TerminusSys

There is one very important thing to understand here. TerminusSys, like most other adwares doesn’t target program weaknesses. Rather it targets the human factor, relying on the user to install it. Of course, since few people will willingly install Adware on their computers, it will use deception. Most of the time Adware will pose as something legitimate, possibly useful and free. Learning the patterns of adware programs will greatly help you to identify them and deny them access to your computer.

  1. Watch out for bundled installers – many programs will offer you additional free extras to install along the main application. Often, especially with freeware, these extras will contain adware. Fortunately you can always install the program you want and block the adware. Always go for the advanced installation option – it will give detailed control over what is installed and you can stop anything you don’t need or looks suspicious.
  2. Watch out for fake download sites – there is a variety of dangerous sites that prey on unsuspecting users. These sites can copy your search terms and instantly generate a temporary file with the exact same name. This nets a 100% search match and pops up in page 1-2 in Google. This file is a virus (of course) and will always end with an .exe regardless of the main file name. Look out for .exe files and NEVER install them, unless you are absolutely certain you are installing a legitimate program.
