Antivir Solution Pro is a rogue anti-spyware program from the same family as Antivirus Soft and AV Security Suite. This family of rogues is installed through the use of malware and exploit kits that download and install Antivir Solution Pro onto your computer without your permission. When this program is installed it will be configured to start automatically when Windows starts, and once started, will perform a scan of your computer and state that it has found numerous infections. It will not, though, tell you the files that are supposedly infected and will also state that you cannot remove anything until you first purchase the program. This is a complete scam, as the program is scripted to display infections every time it is run. That means if you reinstalled Windows and ran Antivir Solution Pro it would still say that you are infected. It does this to scare you into thinking that your computer has a security problem so that you will then purchase the program. When you purchase the program, though, all you do is waste your money as the program has no useful function for your computer.

Antivir Solution Pro is known to be installed through exploit kits on hacked web sites. Exploit kits are are scripts that are added to hacked legitimate web sites that attempt to install malware onto a visitors computer through the use of known vulnerabilities in the Windows operating system and installed applications. Due to this, and to avoid being infected again after your computer is cleaned, it is important that you make sure that your Windows installation is completely up-to-date with all the latest Microsoft security patches. It is also important to make sure that all your programs, which include Sun Java, Adobe Reader, and Adobe Flash, are updated to their latest versions. A great program that you can use to scan your computer for insecure programs is the Secunia Personal Software Inspector. We suggest that all readers scan their computer with this program to make sure your applications are not vulnerable to security exploits in order to add an extra layer of security. A tutorial on how to use Secunia PSI can be found here:

When Antivir Solution Pro is running it will state that most programs are infected when you attempt to run them. The text of this fake infection alert is:

Application cannot be executed. The file notepad.exe is infected. Do you want to active your antivirus software now?

It does this for two reasons. The first is to make you think that your legitimate, and clean, programs are infected so that you will then purchase the rogue. The second reason is to block you from running any legitimate security programs that may help you remove this infection.

While Antivir Solution Pro is running it will also show you fake security alerts that attempt to further scare you into thinking you have a infection on your computer. These alerts will state that active malware has been detected or that your computer is under attack. The text of these alerts is:

Windows Security Alert
Windows reports that computer is infected. Antivirus software helps to protect your computer against viruses and other security threats. Click here for the scan your computer. Your system might be at risk now.

Antivirus Software Alert
Infiltration Alert

Your computer is being attacked by an internet virus. It could be a password-stealing attack, a trojan - dropper or similar.

Just like the other false infections alerts, these warnings are all fake and should be ignored. Last, but not least, Antivir Solution Pro will also configure your computer to use a proxy server at 127.0.0.1:5643, which is actually the Antivir Solution Pro program itself. This makes it that when you browse the web using Internet Explorer, the rogue will intercept all your web browser requests and instead display a page that shows a security warning about the site you are visiting. This warning states:

Internet Explorer warning - visiting this site may harm your computer!
Most likely causes:

  • The website contains exploits that can launch a malicious code on your computer
  • Suspicious network activity
  • There might be an active spyware running on your computer

These warnings should be ignored as they are false. If you use a browser other than Internet Explorer you will not see the warnings at all and can browse the Internet like normal.

Without a doubt, Antivir Solution Pro was created solely to trick you into purchasing the program by convincing you that your computer has a security problem. Now that you know what this program does, it goes without saying that you should not purchase this program for any reason. If you already have purchased it, then we suggest you contact your credit card company and dispute the charges. To remove Antivir Solution Pro and any related malware, please follow the steps in the removal guide below.

Automated Removal Instructions for Antivir Solution Pro using Malwarebytes Anti-Malware:

 

  1. Print out these instructions as we may need to close every window that is open later in the fix.

  2. It is possible that the infection you are trying to remove will not allow you to download files on the infected computer. If you run into this problem when following the steps in this guide you will need to download the files requested in this guide on another computer and then transfer them to the infected computer. You can transfer the files via a CD/DVD, external drive, or USB flash drive.

  3. Reboot your computer into Safe Mode with Networking using the instructions for your version of Windows found in the following tutorial:
    How to start Windows in Safe Mode
    When following the steps in the above tutorial, select Safe Mode with Networking rather than just Safe Mode. When the computer reboots into Safe Mode with Networking make sure you login with the username you normally use. When you are at your Windows desktop, please continue with the rest of the steps.

  4. This infection changes your Windows settings to use a proxy server that will not allow you to browse any pages on the Internet with Internet Explorer or update security software. Regardless of the web browser you use, for these instructions we will first need need to fix this problem so that we can download the utilities we need to remove this infection.

    Please start Internet Explorer, and when the program is open, click on the Tools menu and then select Internet Options as shown in the image below.



    Internet Explorer Tools Menu


  5. You should now be in the Internet Options screen as shown in the image below.



    Internet Options screen



    Now click on the Connections tab as designated by the blue arrow above.

  6. You will now be at the Connections tab as shown by the image below.


    Internet Options connections tab



    Now click on the Lan Settings button as designated by the blue arrow above.

  7. You will now be at the Local Area Network (LAN) settings screen as shown by the image below.



    Proxy Settings screen



    Under the Proxy Server section, please uncheck the checkbox labeled Use a proxy server for your LAN. Then press the OK button to close this screen. Then press the OK button to close the Internet Options screen. Now that you have disabled the proxy server you will be able to browse the web again with Internet Explorer.

  8. Now we must end the processes that belong to Antivir Solution Pro so that it does not interfere with the cleaning procedure. To do this, please download RKill to your desktop from the following link.

    RKill Download Link - (Download page will open in a new tab or browser window.)

    When at the download page, click on the Download Now button labeled iExplore.exe download link. When you are prompted where to save it, please save it on your desktop.

    If you are unable to connect to the site to download RKill, please go back and do steps 3-6 again and make sure the infection has not reenabled the proxy settings. You may have to do this quite a few times before you can get RKill downloaded. If you still cannot download the RKill program on the infected computer, you should download it to a clean computer and copy it to the infected one via a USB flash drive or CDROM.

  9. Once it is downloaded, double-click on the iExplore.exe icon in order to automatically attempt to stop any processes associated with Antivir Solution Pro and other Rogue programs. Please be patient while the program looks for various malware programs and ends them. When it has finished, the black window will automatically close and you can continue with the next step. If you get a message that RKill is an infection, do not be concerned. This message is just a fake warning given by Antivir Solution Pro when it terminates programs that may potentially remove it. If you run into these infections warnings that close RKill, a trick is to leave the warning on the screen and then run RKill again. By not closing the warning, this typically will allow you to bypass the malware trying to protect itself so that RKill can terminate Antivir Solution Pro . So, please try running RKill until the malware is no longer running. You will then be able to proceed with the rest of the guide. Do not reboot your computer after running RKill as the malware programs will start again.

    If you continue having problems running RKill, you can download the other renamed versions of RKill from the RKill download page. Both of these files are renamed copies of RKill, which you can try instead. Please note that the download page will open in a new browser window or tab.


  10. Now you should download Malwarebytes Anti-Malware, or MBAM, from the following location and save it to your desktop:

    Malwarebytes Anti-Malware Download Link (Download page will open in a new window)

    If you are unable to connect to the site to download Malwarebytes', please go back and do steps 3-6 again and make sure the infection has not reenabled the proxy settings.


  11. Once downloaded, close all programs and Windows on your computer, including this one.

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

  13. When the installation begins, keep following the prompts in order to continue with the installation process. Do not make any changes to default settings and when the program has finished installing, make sure you leave both the Update Malwarebytes Anti-Malware and Launch Malwarebytes Anti-Malware checked. Then click on the Finish button. If MalwareBytes' prompts you to reboot, please do not do so.

  14. MBAM will now automatically start and you will see a message stating that you should update the program before performing a scan. As MBAM will automatically update itself after the install, you can press the OK button to close that box and you will now be at the main program as shown below.


    MalwareBytes Anti-Malware Screen

  15. On the Scanner tab, make sure the the Perform full scan option is selected and then click on the Scan button to start scanning your computer for Antivir Solution Pro related files.

  16. MBAM will now start scanning your computer for malware. This process can take quite a while, so we suggest you go and do something else and periodically check on the status of the scan. When MBAM is scanning it will look like the image below.


    MalwareBytes Anti-Malware Scanning Screen

  17. When the scan is finished a message box will appear as shown in the image below.


    MalwareBytes Anti-Malware Scan Finished Screen

    You should click on the OK button to close the message box and continue with the Antivir Solution Pro removal process.

  18. You will now be back at the main Scanner screen. At this point you should click on the Show Results button.

  19. A screen displaying all the malware that the program found will be shown as seen in the image below. Please note that the infections found may be different than what is shown in the image.


    MalwareBytes Scan Results


    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.

  20. When MBAM has finished removing the malware, it will open the scan log and display it in Notepad. Review the log as desired, and then close the Notepad window.

  21. You can now exit the MBAM program.

  22. As many rogues and other malware are installed through vulnerabilities found in out-dated and insecure programs, it is strongly suggested that you use Secunia PSI to scan for vulnerable programs on your computer. A tutorial on how to use Secunia PSI to scan for vulnerable programs can be found here:

    How to detect vulnerable and out-dated programs using Secunia Personal Software Inspector

 

Your computer should now be free of the Antivir Solution Pro program. You may want to consider purchasing the PRO version of Malwarebytes Anti-Malware to protect against these types of threats in the future, as if you had the real-time protection component, that comes with the paid for version, activated it would not have allowed this infection to install.

If you are still having problems with your computer after completing these instructions, then please follow the steps outlined in the topic linked below:
