I have a PC laptop with Windows XP environment. Recently my McAfee subscription ran out and a few days later the computer practically nonfunction due to continuous pop-ups and warnings about pending system failure (adware I think). I have reinstalled the McAfee firewall and anti-virus thing, also scanned with Ad-Aware, Spybot, Panda antivirus and Housecall anti virus as well as McAfee Stinger. Isolated and discarded several infections, scans come up clean now except the McAfee continues to warn me about this Adware-BHO.gen but cant remove it and it seems like it shifts around in the Temp file (I have tried to clean out the temp files). Any suggestions? Thanks.

Have you tried doing your scans in "Safe Mode"? Are you doing scans while logged into the "Administrator Account" or an "account with administrator privileges"?

You need to start there first. If rescanning in Safe Modes does not help, then do this:

Please download ATF Cleaner by Atribune & save it to your desktop. DO NOT use yet.
Please download and install SUPERAntiSpyware Free
  • Double-click SUPERAntiSypware.exe and use the default settings for installation.
  • An icon will be created on your desktop. Double-click that icon to launch the program.
  • If asked to update the program definitions, click "Yes". If not, update the definitions before scanning by selecting "Check for Updates". (If you encounter any problems while downloading the updates, manually download them from here and unzip into the program's folder.)
  • Under "General and Startup", make sure "Start SUPERAntiSpyware when Windows starts" box is unchecked.
  • Under "Configuration and Preferences", click the Preferences button.
  • Click the Scanning Control tab.
  • Under Scanner Options make sure the following are checked (leave all others unchecked):
    • Close browsers before scanning.
    • Scan for tracking cookies.
    • Terminate memory threats before quarantining.
  • Click the "Close" button to leave the control center screen and exit the program.
  • Do not run a scan just yet.
Reboot your computer in "Safe Mode" using the F8 method. To do this, restart your computer and after hearing your computer beep once during startup (but before the Windows icon appears) press the F8 key repeatedly. A menu will appear with several options. Use the arrow keys to navigate and select the option to run Windows in "Safe Mode".

Double-click ATF-Cleaner.exe to run the program.
  • Under Main "Select Files to Delete" choose: Select All.
  • Click the Empty Selected button.
  • If you use Firefox browser click Firefox at the top and choose: Select All
  • Click the Empty Selected button.
    If you would like to keep your saved passwords, please click No at the prompt.
  • If you use Opera browser click Opera at the top and choose: Select All
  • Click the Empty Selected button.
    If you would like to keep your saved passwords, please click No at the prompt.
  • Click Exit on the Main menu to close the program.
Note: On Vista, "Windows Temp" is disabled. To empty "Windows Temp" ATF-Cleaner must be "Run as an Administrator".

Scan with SUPERAntiSpyware as follows:
  • Launch the program and back on the main screen, under "Scan for Harmful Software" click Scan your computer.
  • On the left, make sure you check C:\Fixed Drive.
  • On the right, under "Complete Scan", choose Perform Complete Scan and click "Next".
  • After the scan is complete, a Scan Summary box will appear with potentially harmful items that were detected. Click "OK".
  • Make sure everything has a checkmark next to it and click "Next".
  • A notification will appear that "Quarantine and Removal is Complete". Click "OK" and then click the "Finish" button to return to the main menu.
  • If asked if you want to reboot, click "Yes" and reboot normally.
  • To retrieve the removal information after reboot, launch SUPERAntispyware again.
    • Click Preferences, then click the Statistics/Logs tab.
    • Under Scanner Logs, double-click SUPERAntiSpyware Scan Log.
    • If there are several logs, click the current dated log and press View log. A text file will open in your default text editor.
    • Please copy and paste the Scan Log results in your next reply.
  • Click Close to exit the program.
Then perform an Online Virus Scan like BitDefender.
(These require Internet Explorer to work. Watch the Address bar in IE. You may receive alerts that "This site might require the following ActiveX control...Click here to install...". Click on that alert and then Click Install ActiveX component. If given the option, choose "Quarantine" instead of delete.)

Please print out and follow the generic instructions for using "SmitfraudFix".
(If you have downloaded SmitfraudFix previously, please delete that version and download it again as the tool is frequently updated!)
-- If the tool fails to launch from the Desktop, please move smitfraudFix.exe to the root of the system drive (usually C:\), and run it from there.

After running SmitFraudFix, a text file named rapport.txt will have automatically been saved to the root of the system drive, usually at C:\rapport.txt. Please copy & paste the contents of that text file into your next reply.

Your welcome.

Now 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.
