Trojan Win32/Tiggre!rfn virus removal guide

What is Trojan Win32/Tiggre!rfn?

Hacktool:Win32/Keygen is a rogue tool capable of making fake activation keys for a range of software. The tool doesn't have harmful components, but it is also often developed together alongside other malware. Thus the users who have it installed or may have it present on their system are already likely to be dealing with an infected computer.

Trojan Win32/Tiggre!rfn is high-risk malware designed to perform a number of malicious tasks on victims' computers. It is also known as 'Trojan.GenericKD.12694003' (by BitDefender) and 'W32/Autoit.CGO!tr' (by Fortinet). Trojan Win32/Tiggre!rfn is distributed in various ways, including spam emails (malicious attachments), fake Adobe Flash Player updaters, malicious websites, chain infections, and even Facebook messages.

• As I predicted in my previous post about MessenPass false positives, the number of false positives alerts in the new version of MessenPass increased to 17, according to VirusTotal report. The new false alerts are: a-squared – Trojan.Generic!IK AntiVir – SPR/PSW.Messen.DC Antiy-AVL – PSWTool/Win32.Messen.gen Comodo – UnclassifiedMalware.
• I assume this is a false positive, but haven't risked installing it anyway. I have attached a screenshot of the warning. Re: Windows 10 claims trojan Win32/Vigorf.A is present in.
• HackTool:Win32/Keygen adalah sebuah Trojan yang berisi banyak unik berbahaya tanda dan gejala yang Anda perlu diwaspadai. Aspek yang paling mengkhawatirkan berkaitan dengan HackTool:Win32/Keygen adalah faktor yang HackTool:Win32/Keygen mungkin tampak berguna ketika pada kenyataannya adalah benar-benar sebaliknya langsung.

Trojan Win32/Tiggre!rfn is versatile malware, since it performs various functions depending on developers' choices. For example, it can misuse system resources to mine cryptocurrency. The entire crypto-mining process essentially based on solving various 'mathematical equations'. Mining tools employ system resources to perform calculations. Each time an 'equation' is solved, a single unit of currency (e.g., 1 Bitcoin) is mined. Since an identical 'equation' is solved by a number of computers simultaneously, the reward is split between each device depending on the power of the device and how much work is performed. All revenue is received by cyber criminals (crypto wallet), whilst users receive nothing in return. In fact, all this is done without their consent, and since mining takes up to 100% of computer resources, systems often become unstable and virtually unusable. Furthermore, within certain circumstances (high room temperatures, poor cooling systems, etc.) hardware can be damaged (components might overheat). Trojan Win32/Tiggre!rfn also gathers various data, including saved logins/passwords, keystrokes, banking information, and so on. Collected data is often misused to generate revenue. Therefore, the presence of malware such as Trojan Win32/Tiggre!rfn might lead to serious financial and privacy issues (e.g., cyber criminals can transfer funds to their accounts, purchase illegal items under your name, and so on).

In some cases, Trojan Win32/Tiggre!rfn infiltrates systems along with a number of adware-type applications. These programs are not as harmful as Trojan Win32/Tiggre!rfn, but can be frustrating and problematic. Potentially unwanted adware-type programs (PUPs) typically deliver intrusive advertisements and gather sensitive data. Intrusive ads conceal underlying website content (thereby significantly diminishing the browsing experience), and also redirect to malicious sites and even run scripts that stealthily download and install malware. Clicking these ads can lead to malicious sites. Furthermore, adware gathers IP addresses, URLs visited, search queries, pages viewed, and other data relating to browsing activity. Collected information is shared with third parties (potentially, cyber criminals). Therefore, adware poses a threat to your privacy and Internet browsing safety. For these reasons, all adware-type PUPs must be eliminated immediately.

Trojan Win32/Tiggre!rfn is very similar to Pony, TrickBot, and FormBook. In fact, there are dozens of viruses that also gather information, mine cryptocurrencies, and perform other malicious tasks. Adware-type apps share many similarities. By offering 'useful features', PUPs attempt to give the impression of legitimacy, however, rather than enabling the functions promised, adware poses a direct threat to your privacy and Internet browsing safety. The only purpose of this software is to help developers generate passive revenue.

How did Trojan Win32/Tiggre!rfn infect my computer?

As mentioned above, Trojan Win32/Tiggre!rfn is promoted using spam emails, fake Flash Player updaters, and Facebook. Spam emails contain malicious attachments (e.g., MS Office documents, JavaScript files, etc.) that, once opened, stealthily download and install malware. Fake updaters claim that the player is outdated (although it is not) and encourage users to renew it. Rather than updating the player, however, these tools download and install Trojan Win32/Tiggre!rfn. Criminals also proliferate this malware via malicious sites that, once opened, execute scripts designed to download and install Trojan Win32/Tiggre!rfn without consent. Another method is 'chain-infecting': a computer is infected with malware that proliferates other viruses (in this case, Trojan Win32/Tiggre!rfn). Developers also use scripts that send spam messages on Facebook. The message simply contains a video file, however, this is a disguise - rather than opening the video, the user will open a AutoIt script that will infect the system.

How to avoid installation of malware?

The main reasons for computer infections are poor knowledge and careless behavior. The key to safety is caution. Therefore, pay close attention when browsing the Internet. Think twice before opening files/links received via email, Facebook accounts, Skype, and so on. If files/links seem irrelevant or have been sent from suspicious/unrecognizable names/email addresses, delete these messages immediately and certainly do not open attached files/links. Furthermore, keep installed applications up-to-date and remember that criminals proliferate malware via fake updaters. Therefore, apps should be renewed using implemented update features or tools provided by the official developers only. Having a reputable anti-virus/anti-spyware suite installed and running is also paramount. If you believe that your computer is infected with Trojan Win32/Tiggre!rfn, we recommend running a scan with Malwarebytes for Windows to automatically eliminate infiltrated malware.
