Trojan.Win32.Dialer.a Removal Guide

What is Trojan.Win32.Dialer.a?

Trojan.Win32.Dialer.a – malware that hijacks your internet traffic


Trojan.Win32.Dialer.a is a type of virus that uses a telephone line to connect users' computers to premium-rated services. As a result, victims might lose money, click on malicious links, infected their machines with more malware, or disclose their personal information to cybercriminals.

It is also common that these types of Trojans often automatically redirect users' web traffic to pornographic websites. Hence, those infected might find the content inappropriate, or it could be exposed to children. If you have been suffering from strange redirects to adult sites and other strange behavior, you need to remove this virus from your system ASAP.

Name Trojan.Win32.Dialer.a
Type Malware, dialer
Distribution Spam email attachments or hyperlinks. Also, could be automatically installed by an already existing Trojan
Risks Installation of other malicious software, financial losses due to premium-rate numbers being dialed
Removal The easiest way to delete malware is by performing a full scan with antivirus software
System fix Employ FortectIntego to fix Windows system file damage done by malware automatically

Just like any other malicious software, dialer malware uses illicit methods for its distribution. In most cases, victims might get infected due to another Trojan already present on the device. Alternatively, users might also be tricked into downloading it from malicious websites, believing it is a useful program or opening spam emails that include macro-infused attachments.

Malicious dialers operate on a relatively simple way – it changes the settings of the dial-up without permission. This allows the malware to perform all its malicious activities, i.e., connect to a website that uses premium-rate costs. This harmful activity brings benefits to cybercriminals operating those destination websites.

While the financial losses if one of the negative sides of the infection, the problem is also evident when it comes to inappropriate content.

To make matters worse, there could another Trojan already installed on your computer if Trojan.Win32.Dialer.a is present. During its operation, it might perform the following tasks:

  • Download install other malicious programs
  • Update itself with new features
  • Log keystrokes and record mouse inputs
  • Open a backdoor on the system, allowing a full remote control to the attackers
  • Gather personal information, such as credit card details, login data, etc.

To remove the virus along with other Trojans that could be present on your Windows machine, you should perform a full system scan with security software – we recommend SpyHunter 5Combo Cleaner for the job. Also, to clean up your web browsers and fixing potential damage caused by the virus to Windows system files, use FortectIntego.

Use precautionary measures to avoid malware

As evident, no users would install malicious programs on their computers intentionally. Despite this, most infections happen precisely when victims install malware themselves, although they are tricked into doing so in most cases. Trojans, essentially, are not defined by their operation but rather the distribution method.

Users who install Trojans on their systems believe that the executable they launched is perfectly safe due to one reason or another. In fact, any executable can be called anything to deceive potential victims. It does not matter where such files come from – malicious spam emails, software cracks, pirated program installers, fake anti-spyware apps, or fake notifications on various websites.

In order to protect yourself from such malware attacks, equip your system with security software that would warn you about potential danger. It means that an antivirus and web shield are both needed. Also, avoiding high-risk websites and not opening suspicious emails can decrease the risk of infection significantly.

Make Trojan.Win32.Dialer.a removal an easy task

While it is possible to eliminate malware manually, it is highly not recommended for regulars computer users. Malicious programs perform a variety of changes to the infected devices and drop thousands of malicious files. Hence, if some of the components are not deleted correctly, the re-infection might occur. What makes it worse is that users would believe they are safe while the virus would still be operating in the background.

Therefore, you should download, install, and perform a full system scan with SpyHunter 5Combo Cleaner or another reputable anti-malware software to remove Trojan.Win32.Dialer.a automatically. If this malware is interfering with this process in any way, access Safe Mode as explained below and perform elimination from there. After that, use FortectIntego to fix virus damage quickly and efficiently.

How to prevent from getting dialers

Stream videos without limitations, no matter where you are

There are multiple parties that could find out almost anything about you by checking your online activity. While this is highly unlikely, advertisers and tech companies are constantly tracking you online. The first step to privacy should be a secure browser that focuses on tracker reduction to a minimum.

Even if you employ a secure browser, you will not be able to access websites that are restricted due to local government laws or other reasons. In other words, you may not be able to stream Disney+ or US-based Netflix in some countries. To bypass these restrictions, you can employ a powerful Private Internet Access VPN, which provides dedicated servers for torrenting and streaming, not slowing you down in the process.

Data backups are important – recover your lost files

Ransomware is one of the biggest threats to personal data. Once it is executed on a machine, it launches a sophisticated encryption algorithm that locks all your files, although it does not destroy them. The most common misconception is that anti-malware software can return files to their previous states. This is not true, however, and data remains locked after the malicious payload is deleted.

While regular data backups are the only secure method to recover your files after a ransomware attack, tools such as Data Recovery Pro can also be effective and restore at least some of your lost data.
