How to remove TechBrolo malware

This article covers everything you need to know about the TechBrolo malware or supportscam:js/techbrolo!rfn, what it is, how it works, and how to completely remove it from your computer.

Malware simply means malicious software (or badware), and these are created with the intent to harm or destroy your data, and devices.

This malware is hosted on malicious sites, which is why it takes the form of advertising or paid search results, cold calls from tech support agents, popup warnings or ads, and popular email scams.

What is TechBrolo Malware and how it infects your computer?

TechBrolo is a JavaScript malware (Trojan), usually classified as rogue, or support scam.

The main characteristic of the TechBrolo virus is the fake alerts that require you to call tech support, then pay a fee in order to get assistance.

How TechBrolo gets into your computer system?

Unsuspecting users are tricked into downloading freeware, or opening spam emails, and other third-party installation setups, which ideally is an open door for letting TechBrolo, and other malware in.

Sometimes the usual activity such as playing online games, downloading pirated software, using infected devices, visiting suspicious links such as popups or torrents can get you into trouble.

Updating your programs or applications from unsupported links is also a sure way for TechBrolo to gain access.

Once in, TechBrolo wastes no time and immediately adds malicious codes that corrupt your files and compromise your computer’s security.

Some symptoms you will begin to see (or probably have already) manifest because of TechBrolo include:

  • Bogus popup warnings, and alerts that your computer is at risk due to critical error or severe virus or malware
  • Notice that you should purchase a registered version to overcome those issues

If left unchecked, TechBrolo malware can degrade your system’s performance, change your browser settings and redirect to unusual sites.

It can also insert unknown infections and malicious codes to your Registry Editor and other executable files, keep sending fake error warnings and slows down network connectivity.

What’s worse is that it steals private data (like IP address, login credentials, browsing history etc.) and the next thing is to find out that you have less money in your account.

This is an important step in the process of eliminating the malware as the native antivirus tool from Windows can be effective.

5. Use a dedicated software

If you already performed the steps above, the malware should have gone away and your PC should be safe now.

However, if it had time to act and the antivirus eliminated all the infected files, you will be left with programs that are not functioning properly.

That means you will have to uninstall and reinstall them again. You’ve seen how to uninstall any apps in step 1.3 above.

Unfortunately, the standard uninstallation procedures are not perfect and some files will still reside on your computer, and they may block or clog a future install of the same program.

The solution is to use a dedicated PC cleaning utility that will eliminate absolutely all traces of the program you want to uninstall.

We recommend CCleaner because quick, light on your system, and performs the steps automatically so you won’t bother with any technicalities.

Types of malware

Virus: Just like viruses that affect the human system, computer viruses attach themselves to your files and infect them, then spread hysterically while corrupting your files (sometimes deleting them) and damaging your system’s functionalities. These usually appear on your laptop as .exe or executable files.

Ransomware: This type holds your computer hostage threatening to destroy or erase your files and data, unless a ransom is paid to its creator.

Trojan: The Trojan horse comes across as legitimate software but hides among your other clean files and if it goes unnoticed, it moves silently, creating backdoors in your computer’s security system, which then allows other malware into your system.

Spyware: As its name suggests, this malware is meant to spy on your system. It hides in your system, taking stock of all your online activities while saving important and private details such as your passwords, credit card details, and your browsing history.

Worms: This type infects your devices using your network’s interface. The more devices they find their way into, the higher the rates of infection.

Adware: This disguises itself through advertising software that can compromise your computer’s security system to serve you with ads, which then let in more malware.
