Rootkit.TDSS Removal Guide

What is Rootkit.TDSS?

Rootkit.TDSS – malware that deeply infects Windows system files to operate

Rootkit.TDSS

Rootkit.TDSS, TDL3, or Alureon [Microsoft] is a malicious program designed to hide the existence of any process on the infected machine in order to perform malicious and dangerous actions.

The main purpose of the rootkit is to intercept user web traffic and steal sensitive data such as credit card details, banking credentials, logins, social security numbers, and much more.

The virus may also replace essential system executable files, which may then be used to hide processes and files installed by the attackers. It can also cause several Blue Screen of death crashes when operational.

Name Rootkit.TDSS
Type Rootkit, bootkit
First detection 2007
Function Intercepts user traffic and collects a variety of personally-identifiable and sensitive information
Removal The virus might be very difficult to remove due to its extensive persistence mechanisms. Use robust anti-malware tools to get rid of it in Safe Mode if required
System fix If you noticed that Windows is crashing, works much slower, programs fail to launch, or you face other stability issues, use ReimageIntego to fix malware-caused damage automatically

Rootkit.TDSS is installed without the user's permission through the use of trojan viruses, whereas Trojan virus can download and install additional malware, adware, or even rogue anti-spyware applications. Therefore, it is important to protect your machine with security software that can repel such attacks – we recommend using SpyHunter 5Combo Cleaner or Malwarebytes.

This virus may also infect the MBR sector, which is executed prior to Windows boot. The removal of malware can be complicated, but it is essential.

When your computer is infected with a TDSS rootkit, you may encounter the following symptoms:

  • Google (Bing, Yahoo) search result links will be redirected to various misleading sites that promote rogue products or display bogus advertisements.
  • Security related websites will be blocked.
  • Frequent BSOD errors
  • You won't be able to launch legitimate anti-malware or anti-virus applications.
  • You may find that web pages load slower.

It goes without saying that you should not tolerate the presence of this threat on your Windows machine. Keep in mind that it can record very private personal data, eventually providing access to your online banking or other personal accounts.

It would not be surprising that you would lose money at any time, become a victim of future phishing campaigns, or even suffer from identity theft. Therefore, follow the detailed instructions we provide below in order to remove all the malicious files and components of this rootkit.

How to prevent from getting malware

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.
