When I try to run Hijackthis I get an error :"For some reason your system denied write access to the Hosts file. If any hijacked domains are in this file, HijackThis may NOT be able to fix this.

If that happens you need to edit the file yourself. To do this, click start, run and type :

notepad C:\\Windows\System32\drivers\etc\hosts

and press Enter, find the line(s) HijackThis reports and delete them. Save the file as 'hosts' and reboot."

I have done the above and cannot find the hijackthis reports

Additionally when I try to run combofix it just runs for days and days (hypothetically speaking)

So it seems to me there are some viruses on this computer as Avast has already blocked some from gaining access. The default search engine is Babylon and cannot be changed. It is a Dell Inspiron 1470 4.00gb RAM Windows 7 64-bit. Any help would be much appreciated. Thank you for your time.

Double click on ComboFix.exe & follow the prompts.
  • When finished, it will produce a report for you.
  • Please post the C:\ComboFix.txt
Note:
Do not mouse click ComboFix's window while it's running. That may cause it to stall

Note: If after running ComboFix you get this error message "Illegal operation attempted on a registry key that has been marked for deletion." when attempting to run a program all you need to do is restart the computer to reset the registry.

Please download and run this DDS Scanning Tool. Nothing will be deleted. It will just give me some additional information about your system.

  • Download DDS by sUBs from one of the following links if you no longer have it available. Save it to your desktop.
