The Setup:
- Had Google Redirect on XP Home PC Model Dell 4500S
- Ran SecurityCheck.exe - report txt file was blank ???
- Then ran ComboFix.exe - seemed to run fine & produced report
- then PC would not boot -- Missing or Corrupted hal.dll
- there is no reference to hal.dll in the ComboFix report

- I have the PC booted with Linux Slax CD ver 5 and can see files on hard disk
- The XP Home CD is not available
- Right now the 'infected' PC is turned off so I can post this from a 'clean' pc on the small peer to peer network
- When working on the 'infected' PC I first turn off all the other PC's on the network... is this necessary?
- The peer-to-peer network is connected to a wireless Linksys router which is connected to a cable modem

The Questions:

1 - How can I get the 'infected' PC to boot again to Windows XP Home?
2 - I may be able to post the ComboFix report by turning this PC off, booting the infected PC to Linux Slax CD, and then using one of the browsers on the the Linux CD to access this forum and posting the report... will that help?
3 - Anywhere I can safely download hal.dll or is that necessary?

Thanks for any help... I really need to get this PC working again.

No one should be using ComboFix unless specifically instructed to do so by a Malware Removal Expert who can interpret the logs. It is a powerful tool intended by its creator to be "used under the guidance and supervision of an expert. Using this tool incorrectly could lead to disastrous problems with your operating system such as preventing it from ever starting again. When issues arise with new malware infections or other security tools conflicting with ComboFix, experts are aware of them and can advise users what should or should not be done while providing assistance. Those attempting to use ComboFix on their own do not have such information and are at risk when running the tool in an unsupervised environment. Please read the pinned topic ComboFix usage, Questions, Help? - Look here.

What specific issues are you having that requires using ComboFix?

Thank you Hamulus (and others). I will wait for assistance as advised.

FYI, I was attempting to follow another post here on Google Redirect when I ran SecurityFix and ComboFix... but I see now I should have started my own thread first and gotten a trained assistant.

Thank you again for your kind assistance.

Still hopeful that some kind soul will volunteer to help out here as I really need to get this computer running again.

Since I can boot it to Linux Slax version 5 CD and browse the hard disk I see that Boot.INI is there but has no content.

I don't know if this is contributing to the problem of not booting but just in case...

Is there a generic boot.ini for XP Home... or any safe boot.ini that I could use to just get the PC to boot so additional trouble shooting could be done?

Thanks everyone for the help.
