Toshiba Satellite M45-S355; 1.8 Ghz Intel Processor; 1 GB RAM; 100 GB HDD; XP Home SP2

It started misdirecting websites and opening programs without any program icons being clicked. I ran Nortons AV, Ad-Aware Plus, Spy Sweeper, Panda Totalscan and Trend Micro Housecall. Totalscan found an RKInstaller but couldn't delete it. Someone also told me there was a rootkit on the drive and to reformat. I used the Toshiba recovery CD and noticed that it only did a quick format before reinstalling Windows. Also, it put all the extra junk Toshiba had loaded when it was new and I took it off again.

That was 4 days ago. Since then, the same problems but much less frequently, but also, the blue screen memory dump has happened several times and the computer is slow and never was before the recover. Is it possible the bad stuff was eradicated with a quick format? If so, I'm in TROUBLE because I am clueless as to how to do a complete reformat. I have a Windows XP Pro that was on my previous computer which died and was scraped before I bought this one - - it's an OEM version from 2002, but I don't know if it's okay to use an OEM from another computer or even if it's legal to reuse a Microsoft product even though it's not the same computer but the same owner.

Can anyone advise?

:thumbsup: Last night I ran some different online scans. Everything finds something different. One found over 100 'items' then lost the connection before it finished scanning. If I download HiJackThis and post a log, can someone have a look at it? Thanks.

Reinstalling Windows without first wiping the hard drive with a repartition and/or format will not remove the infection. The reinstall will only overwrite the Windows files. Any malware on the system will still be there afterwards.

If your scans detect the presence of a rootkit on your computer, then you should seriously consider reformatting the hard drive and installing the operating system fresh. A rootkit on your personal computer means you are no longer in control of what information or processes are actually on your computer. You may no longer be able to trust the displays of system information or of active processes running. A rootkit by definition hides programs and files from your view...If I were reformatting the computer in response to a rootkit problem, then I would unplug the computer from power sources and also remove any batteries from the system as well..This is the ultimate means of removing malware, viruses, and rootkits from the computer.

Reformatting the computer or troubleshooting...

However, before doing something like that its best to confirm you have a rootkit and then ask yourself, When should I re-format? How should I reinstall?.

If I download HiJackThis and post a log, can someone have a look at it?

Yes.
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.)

If HijackThis will not run, try renaming it. Open the HijackThis Folder, right-click on the HijackThis.exe file and rename it Scanner.exe. Double-click on Scanner.exe (which is still HijackThis) and then run your scan. If needed, change the .exe to something else such as .bat, .com, .pif, or .scr. Example: Scanner.bat or Scanner.com

When you have done that, post your log in the HijackThis Logs and Malware Removal 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. After doing this, we would appreciate if you post a link to your log back here so we know that your getting help from the HJT Team.

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 "bump" your post or 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.

Thank you, Quietman7 - - I really, really appreciate your reply! Just wanted you to know that I am in the process of completing the instructions for 'Preparation to Post a HiJackThis Log.' Within an hour, I will post the log in the forum for that. Again, thanks so much. Have a wonderful evening!

Dear Quietman7;

I was just reading back over this issue and saw that you had requested I post a 'link' so you'd know I was getting help on the other forum. So sorry I missed that request. I don't know how to post a link, so I wanted you to know that a Malware Expert is helping me in the HiJackThis Log forum. Thanks again for your assistance.

Now that your log is properly posted, 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, nor should you continue to ask for help elsewhere. Doing so can result in system changes which may not show it the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.

From this point on the HJT Team should be the only members that you take advice from, until they have verified your log as clean.

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?".

To avoid confusion, I am closing this topic.
