Most antivirus programs identify 3.exe as malware—e.g. Symantec identifies it as Trojan Horse, and Kaspersky identifies it as not-a-virus:FraudTool.Win32.WinAntiVirus.x.
The 3.exe file is a software component of N/A - Virus.
"3.exe" is a malicious file located within Windows that falls under the category of malware. The file is part of the fake antivirus software, which is titled Antivirus XP 2008. This program that holds the “3.exe” file actually scans the system for viruses and generates actual reports, but attempts to sell the user a Pro version to maximize protection. During the upgrade process, this file steals credit card information and other identifiable details, such as bank numbers, names, and more. There have also been claims that the file installs additional malware and viruses onto the system, especially with the free version.

Important: You should check the 3.exe process on your PC to see if it is a threat. We recommend Security Task Manager for verifying your computer's security. This was one of the Top Download Picks of The Washington Post and PC World.
The following programs have also been shown useful for a deeper analysis: Security Task Manager examines the active 3 process on your computer and clearly tells you what it is doing. Malwarebytes' well-known anti-malware tool tells you if the 3.exe on your computer displays annoying ads, slowing it down. This type of unwanted adware program is not considered by some antivirus software to be a virus and is therefore not marked for cleanup.
A clean and tidy computer is the key requirement for avoiding PC trouble. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.
Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
