Win32 Gen is malware that invades a Windows system and leaves the system open to other malicious attacks because it contains backdoor programs for remote access. Win32 can usually be removed by a good antivirus/anti-malware program.
Malware is a shortened version of the term "malicious software." It is an all-encompassing phrase that refers to viruses, worms and spyware. Win32 Gen is a Trojan horse virus that is used to place other types of malware on a computer system. It can easily go undetected and makes it simple for hackers to get information from the user like credit card numbers, account passwords and other important information that should remain private.
If Win32 Gen malware has been detected on a system, it is recommended that the user quarantine the item using an antivirus program. Then a full system scan should be run which will check for anything the Win32 Gen file has loaded on the computer.
To stay free of Win32 Gen malware in the first place, websites that are unfamiliar should be avoided, and a good antivirus or anti-malware program should always be kept running on the machine. These programs will alert the user when something attempts to install malicious software on the machine and will usually stop the attack by placing the file into quarantine.
