TVRAT virus removal guide

What is TVRAT?

TVRAT is the name of a Remote Administration Trojan (RAT). RATs are malicious programs that allow cybercriminals to access, monitor and control infected machines. There are many legitimate remote access programs that can be used for technical support and other purposes. The main difference is that users between those legitimate programs and RATs is that users install RATs unknowingly. It important to mention that TVRAT is also known as TeamViewer, it runs in the system using the name of a legitimate remote administration software to disguise itself.

TVRAT malware

Typically, cybercriminals attempt to trick users into installing RATs like TVRAT so they could access personal information, record webcam, microphone, and on-screen activity, collect login credentials (e.g., email addresses, usernames and passwords), credit card details, social security numbers, and other sensitive information. It is common that the attackers use RATs to infect computers with other malware, distribute malware to other computers, manage (rename, delete, copy, move, etc.) files, create a botnet to perform DDoS attacks, mine cryptocurrency. It is important to mention that RATs can be capable of gathering confidential information by using a keylogging feature. RATs that can log keystrokes can record keyboard input (extract everything that victims type with a keyboard connected to the infected machine). Usually, RATs (their features) are used to steal information that could be used to hijack (steal) personal accounts (for example, email, social media, banking accounts), steal identities/use personally identifiable information for malicious purposes, make fraudulent purchases, transactions. Also, they often are used to install ransomware, other Trojans, cryptocurrency miners on the already infected machines or other computers, to trick other users into making money transactions, etc. In one way or another, having a RAT installed on the operating system can lead to various serious problems.

In conclusion, being tricked into installing some RAT like TVRAT is likely to be the culprit of problems like identity theft, monetary and data loss, loss of access to personal accounts, computers, and other issues. More examples of RATs are Strigoi Master, ObliqueRAT, and ViperSoftX. Users who suspect that they have a RAT installed on their computers should scan the operating system with a reputable security suite as soon as possible and get rid of any detected threat immediately.

How did TVRAT infiltrate my computer?

In most cases, users infect their computers with unwanted, malicious programs through emails (malspam), shady channels for downloading files/programs, fake software updaters, and unofficial activation ('cracking') tools. Users install malware via emails they download and open malicious attachments or open files downloaded via malicious links in such emails. Some examples of files that can be used to distribute malware via emails are Microsoft Office documents, PDF documents, archive files like RAR, executables (like .exe), and JavaScript files. Shady channels for downloading files are Peer-to-Peer networks like torrents, eMule, freeware download websites, free file hosting websites, unofficial pages, third-party downloads. They can be used to trick users into opening malicious downloads by disguising malicious files as harmless (legitimate). Users install malware when they open those files.

Fake software updaters infect systems when they are designed to exploit bugs, flaws of the outdated software or install malicious software instead of updates, fixes for some installed software. Trojans are malicious programs that, if installed, can cause chain infections. In other words, there are Trojans that are capable of opening backdoors for other malicious programs. Unofficial software activation tools (better known as 'cracking' tools) often infect computers when users try to illegally bypass the activation of licensed software. It is common for cybercriminals to take advantage of users who try to use software without having to pay for it. Typically, cybercriminals inject malicious code into 'cracking' tools (bindle them with malware) to spread unwanted, malicious software.

How to avoid installation of malware?

Emails that have files attached to them or contain website links, and are sent from unknown, suspicious addresses should not be trusted: files or links in such emails can be used to trick recipients into causing installation of some malicious software. Installed programs have to be updated and activated via implemented functions or with tools from their official developers. Other (third-party, unofficial) tools should never be used for that. Moreover, it is not legal to use unofficial ('cracking') tools to activate licensed programs, or use pirated, hacked programs. Furthermore, files and programs should never be downloaded via untrustworthy, unofficial websites, through third-party downloaders, or other sources of this kind (or installed via third party installers). Users should download them from official websites and via direct links only. Additionally, computers should be scanned for viruses on a regular basis, users should do it using a reputable anti-spyware or antivirus software. If you believe that your computer is already infected, we recommend running a scan with Malwarebytes for Windows to automatically eliminate infiltrated malware.

manual malware removal step 5Check the list provided by the Autoruns application and locate the malware file that you want to eliminate.

You should write down its full path and name. Note that some malware hides process names under legitimate Windows process names. At this stage, it is very important to avoid removing system files. After you locate the suspicious program you wish to remove, right click your mouse over its name and choose "Delete".

locate the malware file you want to remove

After removing the malware through the Autoruns application (this ensures that the malware will not run automatically on the next system startup), you should search for the malware name on your computer. Be sure to enable hidden files and folders before proceeding. If you find the filename of the malware, be sure to remove it.

searching for malware file on your computer

Reboot your computer in normal mode. Following these steps should remove any malware from your computer. Note that manual threat removal requires advanced computer skills. If you do not have these skills, leave malware removal to antivirus and anti-malware programs. These steps might not work with advanced malware infections. As always it is best to prevent infection than try to remove malware later. To keep your computer safe, install the latest operating system updates and use antivirus software.

To be sure your computer is free of malware infections, we recommend scanning it with Malwarebytes for Windows.
