How to Remove Vagger Virus | Updated

I wrote this article to help you remove Vagger Virus. This Vagger Virus removal guide works for all Windows versions.

Vagger is a classic Trojan horse. The nefarious program exploits computer systems and web browsers. It can use your machine to infect other devices and steal your personal data. Vagger has a couple of tasks on its agenda. The most important assignment for a Trojan is to establish a botnet. This is how these programs keep themselves active. The other activity has a monetary purpose. The clandestine program collects information on people. The gathered input can serve for different purposes. In most cases, the developers of the virus use personally identifiable information (PII) to break into people’s financial accounts and withdraw their funds. Additionally, there are other applications which we will describe below.

Vagger injects a malicious JavaScript code which allows it to perform background tasks without the user’s knowledge or permission. You are bound to notice the unauthorized activity, but it could take awhile before you do. Vagger exerts high amounts of CPU and RAM memory. Because of this, your machine will become slow and often incapable of completing its assigned tasks. It will often freeze, crash, return error messages, and display the BSoD (Blue Screen of Death). The recurrence of these symptoms will indicate that there is an underlying problem.

Identifying Vagger can be quite challenging for inexperienced computer users. There is an array of issues which can be attributed to symptoms like a sluggish system performance and error reports. To get to the core of the problem, all you need to do is check your Task Manager. This is the fastest and easiest way to identify a familiar infection of this type. Most Trojans run their scheduled operations through a certain process. Vagger runs a process called Trojan:win32/Vagger!rfn. To open your Task Manager, enter the key combination Ctrl+Alt+Delete and then select the option from the menu.

Vagger turns computers into botnets. A botnet consists of a number of devices which are connected with each other. The entire branch is controlled from a remote server. The people behind the Trojan send out commands to the infected devices. Your system will be used to spread copies of Vagger to other computers, located in different parts of the world. Increasing the number of infected machines expands the range of the Trojan and increases the profit margin. Every computer is both a source of information and a potential distributor for the malicious payload. The Trojan also takes over the web browser which gives it access to more data.

Vagger collects all kinds of input from the targeted computers. This encompasses browsing history, tracking cookies, keystrokes, IP address, geographic location, demographic profile, residency, email account, telephone number, email, user names, passwords, financial credentials, and other sensitive details. The developers of the Trojan can use the gathered information to break into your web-based accounts and steal from them. They can withdraw your funds, make purchases, and even open new accounts under your name. Alternatively, the cyber criminals can sell your data on darknet markets. Either way, your personal security will be severely compromised.

Parasites Like Vagger use deceptive techniques to make their way into people’s personal computers. The most common known distribution pattern is software bundles. The Trojan can hitch a ride with another program. The list of viable download clients encompasses freeware, shareware, and pirated applications. The Trojan will be inserted into the installation process as a bonus tool. The developer will set the extra program for install per default. If you do not change the preference, the Trojan will receive the green light. You should read the terms and conditions of the utilities you intend to add to your system and opt for the advanced installation mode. This will reveal the full list of options.

Another common distribution method is spam emails. The person behind the fake message writes a convincing explanation, stating that the recipient has been contacted by a certain entity. Spammers often write on behalf of the national post, the police department, government branches, institutions, banks, and various private companies. There will be an attachment to the letter which should be an official document. In reality, it will contain the payload of the Trojan. You should do your research before opening attachments. Check the email account behind the message. An easier alternative is to transfer Vagger through a drive-by installation. Accessing a corrupted domain can infect you on the spot, so be careful.
