Trojan.Win32.Generic overview

Trojans are malicious programs that can be used for different purposes. Cyber criminals might use them to access the victim's computer and infect it with other malicious programs such as ransomware. Also, to steal personal, confidential information and perform DDoS attacks.

Typically, these malicious programs are disguised as harmless and legitimate software - people are usually unaware that their computers are infected with them. Ransomware is a type of software that encrypts data, thereby rendering it inaccessible unless a ransom is paid.

Programs of this type cause data or financial loss. RATs (Remote Access Trojans/Tools) are programs that are used to access systems remotely. There are a number of RAT versions with differing features. Typically, cyber criminals use these tools for malicious purposes.

For example, to steal passwords and logins of email accounts, bank accounts, messaging systems and other accounts. Also to install malicious programs, steal clipboard data, log keystrokes, and so on. These can be powerful tools that can lead to problems with privacy, financial and data loss, identity theft, and other serious problems.

Various data stealers are used mostly to steal personal information. For example, logins, passwords, browser cookies, autofill data, crypto wallet details, etc. Crypto miners use computer resources (such as CPU) to mine cryptocurrency by solving mathematical problems.

They reduce computer performance, even rendering systems unusable. Infected computers consume more electricity, thus resulting in higher electricity bills. In summary, cyber criminals use these malicious programs to generate revenue in a number of ways.

Trojan.Win32.Generic examples

Some examples of malware that can be detected as threats with the Trojan.Win32.Generic generic detection name include Boston (ransomware), Baldr (stealer), Win32/Malagent (trojan), and Rescoms (RAT). If any of these programs are installed, they should be removed immediately by running a full scan with the installed anti-virus suite.

How did Trojan.Win32.Generic infiltrate my computer?

Malware can be distributed in various ways. Typically, cyber criminals use spam campaigns, trojans, untrustworthy software download sources, fake software updating or unofficial activation tools. They proliferate malware through spam campaigns by sending emails that contain attached files or web links.

Attached files are usually Microsoft Office or PDF documents, archive files (i.e., ZIP, RAR), executables (.exe and other files of this type), JavaScript files, and so on. The main purpose of these emails is to trick people into opening the attachments. When opened, they download and install malicious software.

Trojans are malicious programs that cause chain infections/download and install other malware, however, to cause any damage, a trojan must first be installed. Malicious files are also spread by uploading them to Peer-to-peer (P2P) networks (such as torrents, eMule, and so on), freeware download websites, free file hosting sites and other dubious download sources.

Typically, these files are presented as legitimate, however, if downloaded and opened/executed, they infect computers with high-risk malicious programs.

Fake (unofficial) software updating tools infect systems by exploiting bugs/flaws of outdated (installed) software or by downloading/installing malware rather than updates, fixes, etc. People use software 'cracking' tools to activate licensed software free of charge (illegally), however, these tools often proliferate (download/install) malware.

How to avoid installation of malware?

All software should be downloaded from official websites. None of the aforementioned sources/tools can be trusted. Emails that contain attachments (or web links) and are received from unknown, suspicious email addresses should not be trusted. Additionally, these emails are often irrelevant. The safest way is to leave the attachments and links unopened.

All installed programs must be updated using tools/implemented functions that are provided by official software developers. The same applies to software activation. It is illegal to use 'cracking' tools - these can also install malware. Furthermore, we strongly recommend that you have reputable anti-spyware or anti-virus software installed and enabled.

To keep your system safe, scan it periodically for viruses. If you believe that your computer is already infected, we recommend running a scan with Combo Cleaner Antivirus 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 Combo Cleaner Antivirus for Windows.
