Anti-Virus Number 1 is a clone of the Anti-Virus-1 and Antivirus 2010 rogue anti-spyware programs. This program uses deliberate false advertising to make it appear that Anti-Virus Number 1 is a legitimate program. Like its predecessor, Anti-virus-1, this version displays fake reviews that appear to be from highly respected sites in order to convince you that the program is legitimate. It does this by adding entries to your Windows HOSTS file so that when it displays pop-ups of these fake reviews they appear to be coming from a legitimate site, rather than from a server under the malware developer's control. Some of the sites that this program shows impersonations of include PCMag.com, CNET.com, Download.com, and PC Advisor. This malware is typically installed through the use of Trojans that display fake alerts on your computer stating that you are infected. Once you click on these alerts, Anti-Virus Number 1 will be download and installed onto your computer without your permissions.
Once installed, Anti-Virus Number 1 will be configured to run when Windows starts. Once running, it will scan your computer and display scan results that are scripted to be the same regardless of the computer it is run on. This means that whatever Anti-Virus Number 1 shows during its scans should be ignored as the program was designed to always show those results no matter how clean your computer is. It does this to scare you into thinking you are infected in the hopes that you may purchase the program. While the program is running you will also continue to see alerts being displayed on your desktop stating that your computer is being hacked or that you have active malware on it. The text of some of these alerts include:
Internal conflict alert.

Privacy Violation alert!

All of these alerts, including the scan results, should be ignored as they are just being used as a scam to make you into thinking you are infected. Instead, please use the free removal guide below in order to remove this infection.
Self Help Guide
- Print out these instructions as we will need to close every window that

- At this point you should download Malwarebytes Anti-Malware, or MBAM, to scan your computer for any any infections or adware that may be present. Please download Malwarebytes from the following
location and save it to your desktop:
Malwarebytes Anti-Malware Download Link (Download page will open in a new window)

- Double-click on the icon on your desktop named mbam-setup.exe.
This will start the installation of MBAM onto your computer.

with the installation process. Do not make any changes to default settings
and when the program has finished installing, make sure you leave Launch

Please click on the Scan Now button to start the scan. If there is an update available for Malwarebytes it will automatically download and install it before performing the scan.

take quite a while, so we suggest you do something else and periodically
check on the status of the scan to see when it is finished.
- When MBAM is finished scanning it will display a screen that displays any malware that it has detected. Please note that the infections found may be different
than what is shown in the image below due to the guide being updated for newer versions of MBAM.
You should now click on the Remove Selected button to remove all the listed malware. MBAM will now delete all of the files and registry keys and add them to the programs quarantine. When removing the files, MBAM may require a reboot in order to remove some of them. If it displays a message stating that it needs to reboot, please allow it to do so. Once your computer has rebooted, and you are logged in, please continue with the rest of the steps.
- You can now exit the MBAM program.
Your computer should now be free of the Anti-Virus Number 1 program. If your current anti-virus solution let this infection through, you may want to consider purchasing the PRO version of Malwarebytes Anti-Malware to protect against these types of threats in the future.
