Payslip virus removal guide

What is Payslip?

"Payslip" is an email spam campaign discovered by My Online Security. Cyber criminals use this campaign to spread a trojan-type virus called TrickBot. The email contains text informing users of a 'payment' and encourages them to open an attached MS Office document for more details. This document is malicious - it downloads and installs the aforementioned malware.

The email states that users have received their "payslip". The message also states that the attachment contains detailed information. Bear in mind that this "Payslip" spam campaign is designed to proliferate malware. The email addresses that send this spam typically contain text relating to government and/or taxes (e.g., one discovered email was from amanda.right@tax-service-gov.uk). Research shows that cyber criminals continually register dozens of deceptive email addresses and domains containing names of legitimate companies and government departments. This is done to trick users into opening email attachments - emails received from known companies are more convincing. As mentioned, "Payslip" is used to spread TrickBot - a trojan designed to hijack Internet browsers to collect various logins/passwords. Cyber criminals might gain access to victims' personal accounts (bank, PayPal, social networks, etc.) and misuse them to generate revenue (via money transfers, identity theft, etc.) Therefore, the presence of the TrickBot trojan can lead to serious privacy issues and financial loss. Unfortunately, detecting TrickBot manually is virtually impossible - this malware is extremely good at hiding its tracks. Fortunately, most legitimate anti-virus/anti-spyware suites are capable of detecting and eliminating this virus. If you have already opened "Payslip" attachments, immediately perform a full system scan and remove all detected threats.

TrickBot is virtually identical to FormBook, Pony, Adwind, and a number of other trojan-type viruses. Most are distributed using spam campaigns and are also designed to gather information. Furthermore, some trojans proliferate other viruses, such as ransomware. In doing so, they pose a direct threat to your privacy and Internet browsing safety.

How did Payslip infect my computer?

As mentioned above, malicious attachments are distributed using the "Payslip" campaign download and install malware. Once opened, these MS Office documents immediately ask users to enable macro commands. This triggers the malicious attachments to execute scripts that stealthily download and install TrickBot. Note that that these scripts will only work if the attachment is opened using MS Office. Therefore, users who use other applications capable of reading MS Office formats will not be affected. The malware only targets the Windows Operating System - users who run other platforms are safe.

How to avoid installation of malware?

Lack of knowledge and careless behavior are the main reasons for computer infections. The key to safety is caution. Therefore, pay close attention when browsing the Internet. Carefully analyze received email attachments. Files that seem irrelevant or have been received from a suspicious/unrecognizable email address should never be opened - these emails should be deleted immediately without reading. Furthermore, new versions (2010 and above) of MS Office open downloaded documents in "Protected Mode", thereby preventing malware download/installation. Using older versions is risky. Cyber criminals are also likely to promote rogue applications using the "bundling" method (stealth installation of rogue apps with regular software) and fake software updaters. Therefore, carefully analyze each window of the download/installation process and opt-out of all additionally-included programs. You are strongly advised to download your applications from official sources only, using direct download links. Third party downloaders/installers are monetized by promoting rogue apps, and thus should never be used. The same rule should be followed when updating software. Keep installed applications up-to-date, however, this should be achieved only through implemented functions or tools provided by the official developer. Having a legitimate anti-virus/anti-spyware suite installed and running is also essential. If you have already opened a "Payslip" attachment, we recommend running a scan with Spyhunter for Windows to automatically eliminate infiltrated malware.

After you locate the suspicious program you want to remove, right click the 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, remove it immediately.

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. Unless you 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 better to avoid becoming infected than try to remove malware after infection. 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 Spyhunter for Windows.
