Of course my first post is a problem .. why else would we be here!
I am still infected (not this computer), but my immediate problem is trying to get back online. I had one worm/trojan/virus that had was found in the file ndis.sys. When it got quarantined by Zonealarm Suite (trial)
it took out my network card (and any network cards i put in). So i realized the ndis.sys was missing, so i loaded a copy from another computer (of ndis.sys .. is that "interchangeable" among pc's?), and now it sees the card, and goes online but very slow still. But it still is not right.
I have Windows XP SP2 FYI. Computer is currently disconneted from the internet.

Question is: i have been researching the fixes for the assorted known bugs in my computer, so i have a good idea where to go to fix the registries (so the bugs stop reloading). But should i put that quarantined Ndis.sys back where it was and then try to repair it again (instead of quarantine) with another program like AVG? If i delete it then i will definately lose the Ndis.sys and i dont know how to get it back (yet), other then copy from another computer.

Thank you for any help, when i get the computer back online, and reasonably safe, i will post my hijack this,etc and seek more help. Thanks again!

Hello goaliew

I'm not sure why ZA quarantined the file to begin with. When a program quarantines a file, it is safely held there until you take action to delete it. The reason for doing this is to prevent deletion of an essential file that may have been flagged as a "false positive". If that is the case, then you can restore the file.

I suggest you leave the file alone for now and let an expert have a deeper look as to what's causing your problems by creating a hijackthis log. Please read and follow all instructions in the pinned topic titled "Preparation Guide For Use Before Posting A Hijackthis Log". You may have performed some of these steps already. If you can't perform a step, then skip and continue with the next. In step #9 there are instructions for downloading HijackThis and creating a log. (This is a self-extracting version which will automatically install HJT in the proper location.)

When you have done that, post your log in the HijackThis Logs and Analysis Forum, NOT here, for assistance by the HJT Team Experts. A member of the Team will walk you through, step by step, on how to clean your computer. If you post your log back in this thread, the response from the HJT Team will be delayed because your post will have to be moved. This means it will fall in line behind any others posted that same day.

Start a new topic, give it a relevant title and post your log along with a brief description of your problem, a summary of any anti-malware tools you have used and a summary of any steps that you have performed on your own. Please include the top portion of the HijackThis log that lists version information. An expert will analyze your log and reply with instructions advising you what to fix.

Please be patient. It may take a while to get a response because the HJT Team members are very busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the HJT Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another HJT Team member is already assisting you and not open the thread to respond.

If after 5 days you still have received no response, then post a link to your HJT log in the thread titled "Haven't Had A Reply In Five Days?".

After posting a log you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc.) unless advised by a HJT Team member. Doing so can result in system changes which may not show it the log you already posted. Further, any modifications you make may cause confusion for the member assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.
