After installing a replacement hard drive, and loading Norton AntiVirus, SpySweeper, and Windows, I began getting popups that said I had critcal system errors. I opened one, found that it was an ad for Registry Cleaner32, and realized it was a scam. I found a thread on this site regarding this topic (floweraustin and LoPhatPhuud, August 26), and have followed all advice on this website, as well as the way to clean up from another site called MajorGeeks. I still have the popups, and I can't seem to get rid of them. Please help. I am attaching my HijackThis log. Thanks.

Hi sidney,

Your log looks clean, can you give me a link to the topic. I can't seem to find it, and that enlightens me to what you have.

Have you posted a log at MajorGeeks? If so, it's not smart to post at multiple boards, because different peopl will see unrelated logs.

Please move HijackThis to another location, preferably c:\Program Files\HijackThis. Anywhere is fine, other than your Desktop or a Temp folder. If HijackThis is in a temporary folder you run the risk of accidentally deleting the backups or it clutters your desktop with all the backups.
If you use Windows XP it might be that you just double clicked on the file HijackThis.exe, but that only extracts the file to a temporary folder. Please select the file and Extract it to a folder.

How do you make a permanent folder:

Click "My Computer", then "C:\" and then on "Program Files".
In the menu bar, "File"->"New"->"Folder".
That will create a folder named "New Folder", which you can rename to "HJT" or "HijackThis".
Now you have "C:\Program Files\HijackThis". Put your HijackThis.exe there.
