Hello everyone. I've been having trouble with my computer. Each time I open my internet explorer web browser I have certain chinese ads pop up on my computer. They all have duole8 as part of their web address. I have tried numerous spyware and adware blockers along with a couple different virus detection programs. All were unsuccessful. I have also tried simply blocking the various web addresses as they come up using internet explorer security options. This also did not work. They keep openning up on my computer. I think I need to go in manually to remove this bug, but I do not know what to look for. I have already removed everything I did not recognize. I still have the same problem though. Is there anyone out there that can please help? Thank you very much for your time.

I'm finding referenes to the below file when doing a search on Duole8 pop ups.
C:\WINDOWS\system32\mskey16.dll

Use Windows Search feature > More advanced options to see if mskey16.dll is present. To do this, go to Start -> Search and click For Files or Folders... or just press the Windows key + F key on the keyboard.
  • Click All files and folders.
  • Type in the name of the file under "Search by...criteria."
  • Click More advanced options and check these options:
    • "Search system folders"
    • "Search hidden files and folders"
    • "Search subfolders"
  • Then click "Search" to look for the file(s).
If found right-click the file, choose delete and empty your recycle bin. If you get an error when deleting a file, right-click on it and check to see if the read only attribute is checked. If it is, uncheck it and try again. If you still have problems, then delete the file(s) in "Safe Mode".

Here's the scan log you asked for. None of the ads have come up so far. I hope this works. So, far it seems to be. I'll post another reply if they start openning up again. If not, I'll let you know in about a week or so if the coast seems clear. Those ads were so annoying.

You've been extremely helpful. Your replies were prompt, your directions were clear and concise, and your solutions have produced results where all others have failed. You're awesome! Thank you very much! I'll keep you posted.

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.

Done. I created the new restore point and deleted the old ones. I haven't seen any ads yet. I will let you know in about a week if everything stays good or goes bad again. Thank you very much again. You've been extremely helpful.

Your welcome.

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".

It's been about 2 weeks now and I haven't seen any of those ads pop up on my browser any more. Thank you very much. I think I'm in the clear.
