How to remove MS Antivirus

What is MS Antivirus:

Threat Classification: Rogueware

MS Antivirus is a malicious rogueware that pretends to be a legitimate security program. It produces fake messages that your system has been infected. If you try to remove these infections, MS Antivirus will ask you to buy the full version.

The MS Antivirus rogueware injects itself into the system and changes permission policies and modifies the registry. MS Antivirus is usually installed by the user itself not knowing that this is an actual virus. The threat masks itself as a legitimate program.

The possible distribution of the MS Antivirus varies, but is not limited to – downloading fake Windows updates, installing software “supposedly” required to view an online video, clicking on ads or banners, downloading e-mail attachments or receiving files through a social media website or software.

Once installed, MS Antivirus will take over your system and will present fake messages explaining that your personal information is at risk or that your computer is severely infected by malware. MS Antivirus will try to kill any software you try to run on your computer. These actions are basically its own protection mechanism from legitimate antimalware programs. When this infection terminates a program it will display a message.

Please note that these pop-up notifications are bogus and are used with the only purpose of making you believe that your PC is at risk and fooling you to purchase MS Antivirus. This would generate income for the creators of this infection. Purchasing MS Antivirus will expose your personal information to third-parties and you may also become a victim of a credit card or identity fraud.

This is a high-level, high-risk threat, and it should not be left unattended and this is the reason why you should take actions and remove it immediately, as it is a serious threat to your online identity and security.

!!! Please note that these infections could potentially bring up other malware to your computer and even cause a loss of data. Please do not underestimate such threats.

1. Remove MS Antivirus by restoring your system to a previous state.

1. Reboot your computer into Safe Mode with Command Prompt. To do this, turn your computer off and then back on and immediately when you see anything on the screen, start tapping the F8 key on your keyboard.

***For Windows 8:

If you are using Windows 8, you need to hold the Shift button and tap the F8 key repeatedly, this should boot you into the new advanced “recovery mode”, where you can choose the advanced repair options to show up. On the next screen, you will need to click on the Troubleshoot option, then select Advanced Options and select Windows Startup Settings. Click on the Restart button, and you should now be able to see the Advanced Boot Options screen.

2. Using the arrow keys on your keyboard, select the option “Safe Mode with Command Prompt” and press Enter on your keyboard.

3. When the command prompt loads up, type:

Windows XP: C:\windows\system32\restore\rstrui.exe and press Enter

Windows Vista/7/8: C:\windows\system32\rstrui.exe and press Enter

4. System Restore should initialize, and you will be displayed a list of restore points. Try using a restore point created just before the date and time before the Your-computer-has-been-locked virus has infected your computer.

When System Restore has completed its task, start your computer in Windows normal mode, you would need to perform a scan with anti-spyware software as the infection might still be on the system.
