Disk Antivirus Professional is a computer virus (Rogue.WinWebSec), which pretends to be a legitimate security program and claims that malware has been detected on your computer. If you try to remove these infections, Disk Antivirus Professional will state that you need to buy its “full version” before being able to do so.

Disk Antivirus Professional targets users browsing Internet websites, and rely on social engineering to deliver its payload.
On infected or hacked websites users are prompted by a pop-up window that has been carefully crafted to resemble a legitimate security warning. These pop-up windows typically alert a user of a computer infection, and then prompt the user to download and install Disk Antivirus Professional to resolve the apparent issue.
Some of the infections may have come from users downloading an infected codec file when they were trying to watch a video online, or users who receive a spam email and open an infected email attachment.

Once installed, Disk Antivirus Professional will display fake security alerts that are designed to think that your data is at risk or that your computer is severely infected.These messages include:

Security Monitor: WARNING!
Attention! System detected a potential hazard (TrojanSPM/LX) on your computer that may infect executable files. Your private information and PC safety is at risk.
To get rid of unwanted spyware and keep your computer safe your need to update your current security software.
Click Yes to download official intrusion detection system (IDS software).

Disk Antivirus Professional Warning
Your PC is still infected with dangerous viruses. Activate antivirus protection to prevent data loss and avoid the theft of your credit card details.

Disk Antivirus Professional Warning
Intercepting programs that may compromise your privacy and harm your system have been detected on your PC.

In reality, none of the reported issues are real, and are only used to scare you into buying Disk Antivirus Professional and stealing your personal financial information.

As part of its self-defense mechanism, Disk Antivirus Professional has disabled the Windows system utilities, including the Windows  Task Manager and Registry Editor, and will block you from running certain programs that could lead to its removal.
This rogue antivirus has also modified your Windows files associations, and now whenever you are trying to open a program, Disk Antivirus Professional will block this operation and display a bogus notification in which will report that the file is infected.

Application cannot be executed. The file taskmgr.exe infected.
Please activate your antivirus software.

Disk Antivirus Professional will also hijack your web browser so that it displays a security warnings when attempt to visit a site. The text of this warning is:

Warning! The site you are trying visit may harm your computer!
Your security setting level puts your computer at risk!
Activate Disk Antivirus Professional, and enable safe web surfing (recommended).
Ignore warnings and visit that site in the current stat (not recommended).

When you see this message you can safely click on the Ignore warnings and visit that site in the current state (not recommended) link so that you can visit the site you are trying to go to.
If your computer is infected with Disk Antivirus Professional virus, then you are seeing the following screens:


Disk Antivirus Professional is a scam, and you should ignore any alerts that this malicious software might generate.
Under no circumstance should you buy this rogue security software as this could lead to identity theft,and if you have, you should contact your bank and dispute the charge stating that the program is a scam and a computer virus.
Registration codes for Disk Antivirus Professional
As an optional step,you can use any of the following license keys to register Disk Antivirus Professional and stop the fake alerts.
Disk Antivirus Professional activation code: AA39754E-715219CE
Please keep in mind that entering the above registration code will NOT remove Disk Antivirus Professional from your computer , instead it will just stop the fake alerts so that you’ll be able to complete our removal guide more easily.

    No, it’s not a keylogger. The only issue is when you actually buy this rogue antivirus, as it will sending all your details to these cyber criminals.

  8. This article was immensely helpful. Without it, my P.C. would have been toast. Thank you, Stelian!!

  9. Does the virus STEAL passwords? Or data? Or does it just make you pay?

    And thank you so much for this page.

    God bless you

  10. Hey! It worked…didn’t trust it at the beginning – I’ve tried using internet tutorials in the past but often it seemed that something is missing….but now it worked very well!
    Thank you so much Stelian!

  11. Hello Kelly,
    Right click on your browser icon, and select Run as Administrator… This should allow you to start browser, so that you’ll be able to download Malwarebytes on your computer.
    Stay safe!

  12. I cannot even get on a browser on the infected computer to download the malware! What do I do?? I’m freaking out as I’m trying to prep for finals on Monday!

  13. Hi Stelian,

    Firstly, thanks alot for this great tutorial to fix the Dist Antivirus Professional. I am currently studying for my Masters Degree when my Server that host most of my Study material got infected. The tutorial is great and I followed your steps with great success.

    Secondly, I am a Barcelona supporter and would like to hear your opinion why the team doesn’t have plan-B when we are defending so much. We have to win against AC Malan next week. The team has got tp gel and believe that they cant do it. Thank you!

  14. Worked perfectly on my nice’s hijacked computer. Thanks very much for posting these instructions!!

  15. Just wanted to say that I was able to update Malwarebytes despite this virus but it blocked the actual Malwarebytes so I restarted PC in safe mode and ran it there. It got rid of it no problems. Will try the other programs for extra safety but hate to buy Hitman Pro and already got the free trial which expired.

  16. The world is a better place because of sites like this. Thanks for the info. Worked perfectly. My friend’s computer is a necessity for work and the mistake of letting her niece “play” on the boss’s computer could have been tragic. You saved that little girl’s life….

  41. Cheers for this, this is about the 5th time ive had to use one of your tutorials to delete one of these bloody infections, you guys are a godsend!

  43. THANK YOU!! Worked like a charm! I didn’t have to use the activation code. I DL’d the Chameleon from my working PC to a USB then brought the UBS to my dear grandma’s house. Spent an hour and a half DL’ng and scanning (twice) and it TOTALLY WORKED!! I appreciate this post so much! Thank you!!

  44. Thank you so much – you are a life saver! For those who may run into this – while following these instructions, I ran into error code 26 when trying to activate the HitmanPro. I researched it, and found that after removing malware, it sometimes generates that error code. I did system restore to an earlier point, and then repeated all the steps. It worked after that and activated without any problems.

  45. Perhaps you are wondering, who can you trust to fix your computer? I had the same worry. But I followed Stelian’s instructions, and, like a miracle, it worked. The cyber-thieves were foiled. Good prevailed over evil. Thank you, Stelian. I will spread the word!

  46. I was not able to access any applications [after infection with Disk Anti-virus] but using the registration key stopped the notification pop-ups and I was then able to clean my computer using MalwareBytes.
    Your advice was invaluable and instructions were very clear. . . .thnx for your help

Malewarebytes was being blocked by the “Disk Antivirus” and someone posted a suggestion that after two days he was able to run Malewarebytes after first getting SUPERAntiSpyware to scan and disinfect first. Miraculously I did this and Malewarebytes was in the end able to take out the virus. So grateful to the people who shared the programs and who shared the tips.
