Hello all, I think my comp may have somehow become infected. Starting a couple of days ago, when I go to google or yahoo and perform a search and then click on one of the links, I get redirected to something totally different. Also, I cannot access Windows Update-I get an error message 0x80072ee7. A quick search of the problem has brought me here wondering if I now have some meanies living in my computer somewhere. I'm running windows xp, use both firefox and internet explorer. Neither a virus scan with Eset Nod32 nor a scan with Ad-aware picked anything up. If this looks like something sinister, any help is greatly appreciated!

Thank you,
Comp Challenged

    • 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.

Not sure what all of this means, but even I can see that it is not good. What kind of stuff is this, and is it really a threat?

Thanks again for all the assistance!

Gratefully,
Comp Challenged

Hello, yes it is malware the type usually packed with bogus Codecs. When viewing or perhps listening to a file you were asked to download one of these to be able to see/hear the item. These are generally fraught with malware as you can now vouch for. You can discuss the proper codec for your machine in the Audio or video forums.
I know these codecs are safe. Download K-Lite Codec Pack

So you have removed a lot of junk. You NEED to reboot the PC to remove a few pieces of malware left. How is the PC running now?

Thanks again for the help boopme, however even after removing all the junk the problem still exists. Still getting the same error message when trying to access Windows Update, and still being redirected to other websites when clicking on a link after a yahoo or google search-not every time, but most times. Very frustrating for sure. Any ideas for a next step?
