Hello smart computer people

Here are my symptoms:

-Red circle in system tray with a white "X" in the middle. It is saying that computer is infected and to download something to fix it. I have not clicked on it.

-Home page has been changed.

-When I click on a google search result I get redirected to another search page.

-Computer is slow.

-Tried running Sympatico Security Manager, gets part way through a scan and says that it has encountered a problem and needs to restart the computer.

Can someone please help?

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 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 Scan" 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.
  • 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.
Note: If MBAM encounters a file that is difficult to remove, you may be asked to reboot your computer so it can proceed with the disinfection process. Reagardless if prompted to restart the computer or not, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.

When it removed the files I got a message that it removed some files for windows and I still had the same problem. Did a system restore and that seemed to solve the problem but I am not sure. Went to run the Security Manager and it is telling me " This application has failed to start because AntiFR.dll was not found. Re-installing the application may fix the problem." Do I need to repair windows with the CD, and if so, how?

Forgot to mention I am running Windows XP Home.

AntiFR.dll is not a Windows file. From what I found, it is installed by Virgin Broadband Wireless software (PCguard) along with a lot of other .dll files. Try reinstalling it and see if that fixes the problem.

Problem is when I insert The installation CD, it will not run. Tried going through "My Computer" and clicking on the DVD drive. Still no luck.

I suggest you contact "PCGuard Tech Support" and ask them. Chances are the same issue has already been reported, and a solution is available. If not, the vendor needs to know so that they can investigate.

Thank-you for all your help quietman7!!!

I called my ISP the first time before you told me that the file was actually part of the security software. They were the ones who told me that it was part of the operating system. I then called them back to give them hell for wasting my time and they walked me through the uninstall process and reinstall. Everything seems to be working OK now. Thanks again for all your help!!!!

You're welcome.

If there are no more problems or signs of infection, you should Create a New Restore Point to prevent possible reinfection from an old one. Some of the malware you picked up could have been saved in System Restore. Since this is a protected directory your tools cannot access to delete these files, they sometimes can reinfect your system if you accidentally use an old restore point. Setting a new restore point AFTER cleaning your system will help prevent this and enable your computer to "roll-back" to a clean working state.

The easiest and safest way to do this is:
  • Go to Start > Programs > Accessories > System Tools and click "System Restore".
  • Choose the radio button marked "Create a Restore Point" on the first screen then click "Next". Give the R.P. a name, then click "Create". The new point will be stamped with the current date and time. Keep a log of this so you can find it easily should you need to use System Restore.
  • Then use Disk Cleanup to remove all but the most recently created Restore Point.
  • Go to Start > Run and type: Cleanmgr
  • Click "Ok".
  • Click the "More Options" Tab.
  • Click "Clean Up" in the System Restore section to remove all previous restore points except the newly created one.

Tips to protect yourself against malware and reduce the potential for re-infection, be sure to read:
• "Simple and easy ways to keep your computer safe".
• "How did I get infected?, With steps so it does not happen again!".
• "Best Practices - Internet Safety for 2008".
• "Hardening Windows Security - Part 1 & Part 2".
• "IE Recommended Minimal Security Settings" - "How to Secure Your Web Browser".

• Avoid online gaming sites and peer-to-peer (P2P) or file sharing programs as they are a security risk which can make your system susceptible to a smörgåsbord of malware infections, remote attacks, exposure of personal information, and identity theft. Many malicious worms and Trojans target and spread across P2P files sharing networks and gaming sites. In some instances the infection may cause so much damage to your system that recovery is not possible and the only option is to wipe your drive, reformat and reinstall the OS. The best way to reduce the risk of infection is to avoid gaming sites and not use any P2P applications. Read P2P Software User Advisories and Risks of File-Sharing Technology.
