I am brand new to this forum. I am having the same problem as another post. I have been reading the correspondence, and it has gone beyond my area of expertise.

While running a scan with AVG the program detected Trojan horse Rootkit-Pakes.U infecting my C:\WINDOWS\system32\drivers\atapi.sys file. AVG lists the problem as "white-list" and will not remove or repair because it is a critical system file.

I have downloaded the following applications:

RootRepeal
Avira
Pavark
AVG
Combofix
Malwarebytes
RootRepeal

I tried to download DR (?); but AVG stated it was 'possibly' infected?

I am working on Windows XP Professional; and have upgraded to SP3.

Any help would be greatly appreciated as I have been trying to get rid of this virus for a week and many, many hours.

Hello,Have you run all those downloads? Do not run CombFix.

Run Malwarebytes (MBAM) and Rootrepeal and post those logs.

HI, if AVG is still telling you that you have a rootkit,then...You will need to run HJT/DDS.
Please follow this guide. go and do steps 6 thru 8 ,, Preparation Guide For Use Before Using Hijackthis. Then go here HijackThis Logs and Virus/Trojan/Spyware/Malware Removal ,click New Topic,give it a relevant Title and post that complete log.

Let me know if it went OK.

Hello,

I'm going to delete the DDS logs you posted in the Am I Infected forum, I presume accidentally.

Now that you have posted a log in the HiJack This forum here: http://www.bleepingcomputer.com/forums/t/268170/infected-with-pakesu-located-in-cwindowssystem32driversatapisysdll/ 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 ask for help elsewhere. Doing so can result in system changes which may not show in 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 EXTREMELY 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.

Please be patient. It may take several days, up to two weeks perhaps less, to get a response but your log will be reviewed and answered as soon as possible. I advise checking your topic once a day for responses as the e-mail notification system is unreliable.

To avoid confusion, I am closing this topic. Good luck with your log.

Orange Blossom :thumbsup:
Help us help you. If HelpBot replies, you MUST follow step 1 in its reply so we know you need help.
