Good troubleshooting so far — ’s conservative use of HijackThis backups and selective fixes was the right approach, and ’s follow‑up shows the immediate startup symptom has been removed. ’s reminder to treat an AV detection as an indicator (not the final word) is also important: antivirus flags help point to where to look, but they don’t always tell you whether everything related to that infection is gone.

Short checklist to finish this cleanly (Windows 98 SE specifics):

  • Update the antivirus signatures and run a full scan from Safe Mode; if AVG can’t delete a file, stop the process that holds it (Task Manager) and delete from Safe Mode or from an external scanner.
  • Use HijackThis only for items you understand or that trusted helpers have identified; always save the HJT backup before fixing anything.
  • Inspect browser helper objects and ActiveX/DPF entries by checking the file’s properties (publisher/vendor and file path). Legitimate components usually show a known vendor and live in system or program folders; unknown DLLs running from Temp or the root are suspicious.
  • Back up personal data to removable media before attempting invasive removals; if key system files appear corrupted or multiple infection traces remain, a clean reinstall is often faster and safer on an old machine.

Notes and cautions

  • Windows 98 SE does not implement System Restore (that applies to later Windows editions), so the “restore point reinfection” route is not relevant here — but it is a real concern on newer systems.
  • Keep the machine offline while performing removal steps and avoid deleting registry or system items unless you are sure; when in doubt, create a copy of the suspect file and scan it on a second, up‑to‑date PC or with a multi‑engine scanner before permanent removal.

If those steps leave any doubt, collecting a fresh HJT log and a short list of any persistent running processes will make it easy for someone to give the final thumbs‑up.

Important: Create a folder on the C: drive called C:\HJT.
You can do this by going to My Computer (Windows key+e) then double click on C: then right click and select New then Folder and name it HJT.
Unzip HijackThis into this folder. When you run HijackThis from this folder and have it "Fixed checked" it will create a backup file of modifications to use if restore is necessary.

Have Hijack This fix the following by placing a check in the appropriate boxes and selecting fix checked. Make sure all browser and all Windows Explorer windows are closed before fixing.

Some info on the trojan:

http://www.google.com/search?hl=en&ie=UTF-8&q=Dyfica+Trojan&btnG=Google+Search

Note the references to disabling System Restore and running your utilities in Safe Mode. If system restore is enabled, and the virus was present at the time your last restore point was taken, the virus can be reintroduced to your system that way.

Blessings to you!
