How to Remove Antivirus Center (Uninstall Guide)

Tell your friends:
Antivirus Center is a fake anti-virus program that presents endless security alerts, requesting payment for a licence to remove the non-existent spyware, viruses, trojan horses and other malicious software. The poor spelling used in some of the alerts and pop-ups clearly indicates that Antivirus Center is not a legitimate security product. It also tries to look like Windows Defender which is a perfectly legitimate anti-spyware program. Besides, it reports exactly the same security threats and viruses on different computers. That means the rogue Antivirus Center doesn't even scan your computer but displays predefined infections. That's why this program is defined as scareware. Do not follow the on-screen instructions and do not purchase this rogue anti-virus program; otherwise, you may be subjected to monetary theft, or in a worst-case example, ID Theft. If Antivirus Center has infected your PC, you should remove it immediately. We've got the removal instructions to help you to remove this fake AV. Please follow the steps in the removal guide below. Hopefully it will help some of you.



Antivirus Center runs every time Windows starts. It stops the Windows Security Center (wscsvc) and modifies Windows Registry. It uses the rundll32.exe application to launch functionality stored in a .dat file. So, if you open up the list of running processes in the Task Manager, you won't see any .dat file running but rather just the rundll32.exe. It may block some other programs on your computer and hijack your web browsers. What is more, Antivirus Center displays a bunch of fake security alerts labeled "Antivirus Center" and "Antivirus Center Firewall Alert" saying that your computer is infected by Spyware.IEMonster and some key loggers that may send your sensitive information to remote servers. Just some basic stuff that pretty much every fake AV displays to fool you into thinking that your PC is badly infected. The text of some of the fake alerts is:
Antivirus Center
Spyware.IEMonster process is found. The virus is going to send your passwords from Internet browser (Explorer, Mozilla Firefox, Outlook & others) to the third-parties. Click here for further protection of your data with Antivirus Center.

Antivirus Center Firewall Alert
Suspicious activity in your registry system space was detected. Rogue malware detected in your system. Data leaks and system damage are possible. Please use a deep scan option.

Antivirus Center Firewall Alert
Warning
Keylogger activity detected!
Your account in social network is under attack. Click here to block unauthorized modification by removing threats (Recommended)
To remove Antivirus Center you should restart your computer in safe mode with networking, download anti-malware software and run a full system scan. If you choose to deal with the infection manually, you will have to navigate to %CommonAppData%, locate the file [SET OF RANDOM CHARACTERS].dat and delete it. To stop the annoying alerts, you can use this code D13F-3B7D-B3C5-BD84 to activate the rogue program. Please note, that Antivirus Center may download/drop additional malware onto your computer. That's why we strongly recommend you to use malware removal tools. Last, but not least, if you have already purchased it, please contact your credit card company and dispute the charges. Clarifications and comments are welcome as usual. If you have questions, please leave a comment below. Good luck and be safe online!
