What Is Win32 Malware.Gen?
Learn how to protect your computer from infection from Win32 Malware.Gen files and how to remove existing malware files.
Anti-virus applications use a variety of methods to determine whether a file is malicious, from comparing a file's contents against a database of known threats to analyzing the behavior or structure of a program to see if it exhibits patterns commonly found in malware. Generic threats are files that appear suspicious to your anti-virus program but do not match any known threat. An alert from your anti-virus program warning you that it detected Win32 Malware.Gen on your computer, therefore, indicates that a 32-bit file on your Windows PC may be malicious.
Anti-virus applications sometimes mistakenly label legitimate files as malware, for example if the file performs actions normally associated with malicious programs. If you are certain the file you downloaded or copied to your PC is malware-free, select Ignore from the anti-virus program's warning window to dismiss the alert.
Definition of Malware
The term malware is an umbrella term for any kind of malicious software, from critical backdoor tools that give criminals full control of your PC to less severe threats, such as programs displaying pop-up advertisements at regular intervals. Criminals who create malware applications do so for various reasons, from trying to make a quick buck to simply inconveniencing whoever installs their virus.
Files That Can Contain Malware
Files that can install or run malware on a computer are typically either:
- Executable files, such as the ubiquitous EXE file type.
- Files that contain scripts, such as screen savers, Word or Excel files, PDFs or Web pages.
Media files such as JPGs, AVIs or WMVs, while not executable files, can also contain malicious code targeting a weakness in a specific media player or picture viewer, a technique known as an exploit.
Prevention Against Malware
To keep your computer free from malware, avoid opening suspicious files without first scanning them with an anti-virus application or an online file scanner such as VirusTotal, Metascan Online or Fortiguard's Online Virus Scanner.
Suspicious files or documents include:
- Files received from an untrusted or unknown contact.
- Files received on a USB drive. While the drive may come from a trusted contact, it could contain malware installed without that person's knowledge.
- Files downloaded from high-risk websites, such as warez or adult sites.
To prevent Web pages from downloading and installing malware on your PC, consider disabling scripting in your browser's settings before visiting high-risk or suspicious websites.
Detect and Remove Malware
Update your anti-virus software's definition files frequently to ensure optimal threat detection and removal.
