A short history - First of all, I am running XP home edition. About midnite this past Saturday (today is Monday) I was hit with Antivirus XP 2008. I tried a couple methods of removing it (including one from 2007 that I found on Bleeping Computer), but they talked about XPAntivirus instead of Antivirus XP 2008, which leads me to think that I am dealing with a newer version. I did succeed in removing several of the offending files, but the icon remained in my system tray, and gave me a new virus message every minute or so. Also, my desktop background was eliminated and the background became a cobalt blue, with a "Your computer is infected, etc." message box that won't go away.

Since my current anti-virus software - PC Cillin, which came with the computer - did not prevent the infection, nor did it rid me of all the associated files, I downloaded and ran Norton 360. If found three offending files that may or may not have been associated with Antivirus XP, so I instructed it to delete them.

So here is where I am at this point: the offending icon in the system tray is gone, but so are most of the other icons that were there. The "you are infected" message box and the solid blue background are still on the desktop. My desktop icons are still there, but the vast majority of them don't work. Whenever I try them I get the following message: "This file does not have a program associated with it for performing this action. Create an association in the Folder Options control panel." When I saw that the desktop icons did not work, I tried using the start menu and selecting programs that way, but again, I get the same message. I also tried going to the control panel to change my desktop background back to what it had been, but also got the same error mesage as above.

Any help would be greatly appreciated. THB

Please download Malwarebytes Anti-Malware and save it to your desktop.
alternate download link 1
alternate download link 2
  • Make sure you are connected to the Internet.
  • Double-click on Download_mbam-setup.exe to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
MBAM will automatically start and you will be asked to update the program before performing a scan.
  • If an update is found, the program will automatically update itself.
  • Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the updates, manually download them from here and just double-click on mbam-rules.exe to install.
On the Scanner tab:
  • Make sure the "Perform Quick Acan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
Back at the main Scanner screen:
  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad and you may be prompted to restart your computer. (see Note below)
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply and exit MBAM.
Instructions with screenshots if needed.

Note: If MBAM encounters a file that is difficult to remove, you will be presented with 1 of 2 prompts. Click OK to either and let MBAM proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot will prevent MBAM from removing all the malware.

Some malware infections target .exe files and without repairing that file association your .exe files will lose functionality.

The first thing to try is to check your file association for .exe files. Open the "File Types" dialog box in Windows Explorer or My Computer. Go to Tools > Folder Options > File Types tab. Scroll down to where .EXE would be in the alphabetical order and make certain .EXE is not there. If it is, then edit it there by changing the association to Application. Select the New button, type in EXE for the extension and select the Advanced button. From the list pick "Application."

If that does not resolve the problem, try downloading EXE File Association Fix and save to your Desktop. Extract (unzip) xp_exe_fix.zip and double-click on xp_exe.fix.reg and choose "Yes" to merge it into the registry when prompted. Once you get a successful message delete the file and reboot.

Also see:
"Unable to Start a Program with an .exe File Extension"
"Fix or Restore Broken .EXE .LNK .COM Association Caused by Virus"

Note: Some of these steps involve making changes in the registry. Always back up your registry before making any changes. If you are not familiar with working in the registry, then you should NOT attempt to make any changes on your own. Improper changes to the registry could adversely affect your computer and render it inoperable.

The desktop icons and the icons on the start menu are now working. However, the Antivirus XP 2008 seems to be back. There was an icon on the desktop which I just deleted, plus the blue screen background with the virus warning is still on my desktop. Also there is the antivirus xp icon in my sytem tray again. Every nimute or so I am getting a virus message from the icon telling me of the several hundred viruses it has suuposedly found. So basically I am back to having my computer working, but the Antivirus XP problem is still here.

Here is the text of the scan you had me do in your first reply.

If you're using Windows 2000/XP, please print out and follow the instructions for using SDFix in BC's self-help tutorial "How to use SDFix".
-- When using this tool, you must use the Administrator's account or an account with "Administrative rights"
-- Disconnect from the Internet and temporarily disable your anti-virus and any anti-malware real time protection before performing a scan.

When done, the SDFix report log will open in notepad and automatically be saved in the SDFix folder as Report.txt. Please copy and paste the contents of Report.txt in your next reply. Be sure to renable you anti-virus and and other security programs before connecting to the Internet.

One of the identified infections (sysrest.sys) was a rootkit component installed by a backdoor Trojan. Backdoor Trojans, IRCBots and rootkits are very dangerous because they provide a means of accessing a computer system that bypasses security mechanisms and steal sensitive information like passwords, personal and financial data which they send back to the hacker. Remote attackers use backdoor Trojans and rootkits as part of an exploit to gain unauthorized access to a computer and take control of it without your knowledge. Read Danger: Remote Access Trojans.

If your computer was used for online banking, has credit card information or other sensitive data on it, all passwords should be changed immediately to include those used for banking, email, eBay, paypal and online forums. You should consider them to be compromised. They should be changed by using a different computer and not the infected one. If not, an attacker may get the new passwords and transaction information. Banking and credit card institutions should be notified of the possible security breach. Because your computer was compromised please read How Do I Handle Possible Identify Theft, Internet Fraud and CC Fraud?

Although the backdoor Trojan was identified and removed, your PC has likely been compromised and there is no way to be sure the computer can ever be trusted again. It is dangerous and incorrect to assume that because the backdoor Trojan has been removed the computer is now secure. Many experts in the security community believe that once infected with this type of malware, the best course of action is to wipe the drive clean, reformat and reinstall the OS. Please read "When should I re-format? How should I reinstall?" and "Help: I Got Hacked. Now What Do I Do?".

Should you decide not to follow that advice, we will do our best to help clean the computer of any infections but we cannot guarantee it to be trustworthy or that the removal will be successful. If you wish to proceed, please do the following.

Please read the pinned topic titled "Preparation Guide For Use Before Posting A Hijackthis Log" and complete all the steps. There are instructions for downloading and running Deckard's System Scanner (DSS) which will create a hijackthis log for you, or automatically download and install the most current version of HijackThis if it's not already installed on your computer.

When you have done that, post your log in the HijackThis Logs and Malware Removal forum, NOT here, for assistance by the HJT Team Experts. A member of the Team will walk you through, step by step, on how to clean your computer. If you post your log back in this thread, the response from the HJT Team will be delayed because your post will have to be moved. This means it will fall in line behind any others posted that same day.

Start a new topic, give it a relevant title and post your log along with a brief description of your problem, a summary of any anti-malware tools you have used and a summary of any steps that you have performed on your own. An expert will analyze your log and reply with instructions advising you what to fix. After doing this, we would appreciate if you post a link to your log back here so we know that your getting help from the HJT Team.

Please be patient. It may take a while to get a response because the HJT Team members are very busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT "bump" your post or make another reply until it has been responded to by a member of the HJT Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another HJT Team member is already assisting you and not open the thread to respond.
