Istbar Tool is a dangerous program that initiates serious havoc on the affected computer system

Istbar Tool virus

Istbar Tool — a potentially unwanted application from the developer Integrated Search Technologies that gets installed on the browser without users' consent. After clicking on various windows that it displays, victims are redirected to insecure sites, like online gambling domains or sites filled with adult content. The app also pushes its victims into downloading other rogue tools, typically fake optimizers, that are working on swindling the money from inexperienced PC users. The behavior of Istbar adware significantly affects the performance of your device and diminishes your time online because it runs even if there is an adblocker installed. Unfortunately, in addition to adware functionalities, this malicious intruder has also been attributed to other types of malware.

Name Istbar 
Type Adware
detected as JS Istbar
Category Potentially unwanted program/adware/virus
Symptoms Installs questionable extensions, delivers advertisements, causes redirects
Distribution Software bundles, deceptive ads
Removal Use Reimage Reimage Cleaner Intego for general cleaning after you uninstall Istbar

If Istbar virus has already appeared on your system, the first thing you should note is that it cannot be trusted and left on the device for too long. For the infiltration, it mostly relies on a deceptive marketing technique called bundling[1]. Any program that comes together with software bundles can hardly be trusted because it relies on this method to hide from the victim and infiltrate the computer without being noticed.

Additionally, such malware tends to edit the computer's registry to start its work upon every computer's reboot and make sure that commercial content is delivered continuously to your screen. These ads can be dangerous as they can redirect you to highly suspicious sites seeking to increase their web traffic.

Istbar.exe – the first sign of infection

The main payload of this intruder is Istbar.exe, which is launched every time your device is loaded. Also, you can find additional files on the system:

  • IstBar_DH.dll;
  • istbar.dll;
  • istbarcm.dll;
  • istdownload.exe;
  • cmctl.dll;
  • istbarcm.dll;
  • ysbactivex.dll.

However, the virus can also be found as TrojanDownloader:JS/Istbar.AI or JS Istbar because it has been actively using Javascript to disable certain system's components and launch its malicious ads.[2] The association with the trojan horse[3] should not be taken carelessly. The threat can also install additional unwanted ActiveX components.

Take care of Istbar Tool removal from the system as soon as possible because you cannot be sure that additional intruders won't be installed while this virus is hiding in your PC system. Use Reimage Reimage Cleaner Intego or other similar anti-malware tools to see if there is anything malicious on your PC system. 

We understand that you want to forget about all of this intrusive content and redirects without any delay. That's why we prepared a guide down below which is going to answer the question how to remove adware Istbar from the system manually. The whole process is not difficult – you just need to understand that a full system scan is crucial after you install this malware to make sure that all malicious components are gone.

The automatic removal is the best option because additional malware is removed this way. When your system is thoroughly scanned and cleaned, you can work on your PC as normal again. Researches[4] always note that occasional system scan improves the performance of your computer significantly.

Software bundles distribute all kinds of intruders

Probably deceptive marketing technique that is known the most for distributing cyber intruders is software bundling. This method is widely used to spread all potentially unwanted programs that annoy people in a major way. You should think about the possibility of getting unwanted applications and choose Advanced or Custom installation options every time. 

Unfortunately, people tend to skip through steps during these processes and this way they keep the system at risk. During Default or Quick installations, you agree to every additional piece like an extension, plug-in or toolbar. Then your system starts to run slow and crash from time to time due to background processes. Pay more attention and be cautious about additional programs.

Istbar Tool removal should be a quick process if you use reputable tools

When it comes to PUPs and more serious viruses, you need to be cautious and employ tools designed to eliminate such threats from the system with only one click. Istbar Tool removal requires professional tools because of the additional associations with trojans and other cyber threats. A full system scan detects all possible intruders and improves the speed of your device and the whole functionality.
