Uninstall Trezaa Malware (What is Trezaa?)


If you are looking at this page, you have undoubtedly noticed unusual behavior on your PC. Either in the form of advertisements, excessive pop-up ads, random opening of webpages and/or other unwanted tabs, and worst case scenario: opening of additional browsers when you have no intentions to use them. You have probably also noticed that this is not happening just with Chrome, for instance, but with Mozilla Firefox and Internet Explorer too.

This article will help you to understand what exactly has happened or is happening with your PC, how to remove Trezaa Malware and how to protect yourself for the future. If you still have questions, you’re welcome to leave them as comments and we will reply to you in a timely manner.

What’s happening?

This is what everyone has wondered once their computer is not being its regular self anymore. We live in a digital era where computers and other digital inventions have taken over most of what used to be ‘man-done work’. Along with the convenience of it and efficiency, hackers are taking advantage of our naive trust in computers, programs, etc. They know how we think, what we use our devices for and have created threats that attack us on a regular basis. A decade ago a computer malware was just that: a virus. Now the word is not a good enough definition as there are many types and kinds of viruses. Today, we will tell you of Trezaa Malware. As much as some still consider it not to be a virus and even a legal software, the truth is that it is not — it is harmful.

Trezaa Malware could be easily spotted by simply paying close attention to the advertisements and pop-up ads on the web pages you visit. Yes, it is always nice to catch a good promo-ad about a discounted vacation on the Hawaii islands, but is this really coming from a legit tourist company? Well, if the ad looks suspicious in any way, such as: flashing images, changing content, asking for a good amount of money as a security deposit, or if it is simply prompting you to click on it — “you’re one click away from your dream vacation!”, kind of thin — then it is 100% a sham. The more you click on such ads, the more they will continue to pop-up and the only way you can escape is to find the virus and remove it off your PC.

Another sign of Trezaa Malware is something we call “browser hijacker”. Simply put: this is when you are working on your computer and suddenly random web pages begin to open or additional browsers. The content seen on these websites is usually, again, something of the type of the ad mentioned above or even worse, inappropriate. This is as high as the red flag can go to signalize that something is definitely gotten into your computer and needs your prompt attention and to be uninstalled. Any delay of removing will cause further infection to your files!

Let’s look another aspect of Trezaa Malware now… How is it distributed?

There are more ways for Trezaa Malware to be spread than you and I know. Hackers are called that for a reason. Either via infected e-mail messages, such as the phishing e-mails  — they tend to appear like any other regular e-mail you receive, but end up having no text, changing and/or self-deleting text or are simply flashing — or through letters from your Spam box/folder, or via “software bundle” — you have downloaded a program and along with it you have unintentionally downloaded few others that are carriers of the virus — when a hacker has determined that the malware needs to be spread, they will find a way to do it.

You are strongly encouraged to read carefully the removal guide attached below, familiarize yourself with the basic removal techniques and don’t be afraid to apply them when the unusual PC behavior begins. It is only in your best interest to do so.

What is Trezaa?

If you decided to skip the article – here is the answer. Trezaa is a malware that needs to be uninstalled from your PC immediately. It may be hiding under other names and guises, but you should not be fooled if you simply follow the removal instructions below.


Reboot in Safe Mode (use this guide if you don’t know how to do it).

This was the first preparation.


Reveal All Hidden Files and Folders.

  • Do not skip this  – Trezaa Malware may have hidden some of its files.

Hold together the Start Key and R. Type appwiz.cpl –> OK.


You are now in the Control Panel. Look for suspicious entries. Uninstall it/them. If you see a screen like this when you click Uninstall, choose NO:


Type msconfig in the search field and hit enter. A window will pop-up:


Startup —> Uncheck entries that have “Unknown” as Manufacturer.


Hold the Start Key and R –  copy + paste the following and click OK:

notepad %windir%/system32/Drivers/etc/hosts

A new file will open. If you are hacked, there will be a bunch of other IPs connected to you at the bottom. Look at the image below:

hosts_opt (1)

If there are suspicious IPs below “Localhost” – write to us in the comments.

Open the Start Menu, type “Control Panel” in the search box —> Enter. Network and Internet —> Network and Sharing Center —> Change Adapter Settings. Right-click your Internet connection —> Properties.

In Networking, left click Internet Protocol Version 4 —> Properties. If everything is normal, your window will look like this:

DNS Settings

If it’s not, click on the two “automatic” choices. NOTE: If you are in a domain network, contact your Domain Administrator so he can make these settings, or this may break your Internet Connection.


Right click on the browser’s shortcut —> Properties.

NOTE: We are showing Google Chrome, but you can do this for Firefox and IE (or Edge) as well.


Properties —–> Shortcut. In Target, remove everything after .exe.

Right click on each of the virus processes and select Open File Location, then End the process. Copy the folders somewhere (as a backup if you make a mistake) and delete the directories you were sent to.


Type Regedit in the windows search field and press Enter.

Inside, press CTRL and F together and type the virus’s Name. Right click and delete any entries you find with a similar name. If they don’t show this way, go manually to these directories and delete/uninstall them:

  • HKEY_CURRENT_USER—-Software—–Random Directory. It could be any one of them – ask us if you can’t discern which ones are malicious.
    HKEY_CURRENT_USER—-Software—Microsoft—-Windows—CurrentVersion—Run– Random
