Please print out or copy this page to Notepad. Make sure to work through the fixes in the exact order it is mentioned below. If there's anything that you don't understand, ask your question(s) before proceeding with the fixes. You should 'not' have any open browsers when you are following the procedures below.
Go to My Computer->Tools->Folder Options->View tab:
* Under the Hidden files and folders heading, select Show hidden files and folders.

* Click Yes to confirm and then click OK.
For the options that you checked/enabled earlier, you may uncheck them after your log is clean. If we ask you to fix a program that you use or want to keep, please post back saying that (we don't know every program that exists, so we may tell you to delete a program that we think is bad to keep).
Make sure you downloaded, installed, updated and ran these programs already - Ad-aware, Spybot and Microsoft AntiSpyware. If you didn't, do them now. For more information, go to

Download AboutBuster
http://www.greyknight17.com/spy/AboutBuster.zip and unzip the files to a folder on your Desktop. Run AboutBuster and click OK. Click Update button to see if there are any updates. Close the program now.
Restart your computer and boot into Safe Mode by hitting the F8 key repeatedly until a menu shows up (and choose Safe Mode from the list). In some systems, this may be the F5 key, so try that if F8 doesn't work. Make sure to close any open browsers.
Run a scan in HijackThis. Check each of the following and hit 'Fix checked' (after checking them) if they still exist (make sure not to miss any):

Click Start then run. Type in
regsvr32 /u dskrfuoui.dll Click OK
Run AboutBuster and click Begin Removal button. Once that's done, just hit the OK button. Click Exit once you are done. Click the OK button and it should exit. Open up the 'Ab LogFile.txt' (which was created in the same folder as AboutBuster) and post the log here.
