USPS Virus Email Infected My Computer

The other day, a co-worker of mine had her computer infected when she opened up a email from, a user claiming to be, the USPS. It stated that the package that was sent was undeliverable, and that the attached file contain more info. I found out later that this was a virus, which I assumed. My co-worker opened the attachment out of confusion. I have been trying to delete this virus, but one file continues to return. The file is in the SYSTEM32 folder and it is named sys.dat. We have run the following programs to try to remove this file, but none have worked. We ran Norton, HouseCall 7, Malwarebytes Anti Malware, and Hijack This. We have the Hijack This logs, and will be happy to post them if you need me to. We have also tried to follow the directions on the Symantec website. The computer is running slow at times, but I know that there are things going on in the background. Please help if you get a chance.

Thanks!

Hello new_mm and to BleepingComputer!

Please do not post your HJT-log in this forum! HJT-logs are only allowed in the HJT-forum. Instead start a new thread HERE and include a link to this thread. Please make sure that you read the information about getting started before you start your thread.

It would be helpful if you post a note here once you have completed the steps in the guide and have started your topic in malware removal. Good luck and be patient. Help is on the way!

If you have any more question, I will be happy to reply them here!

Hello new_mm, since you started a new topic in the HJT-forum, I will request this topic to be closed.

Thank you for the response. I posted a new topic following the instructions you linked to. Then new topic url is: http://www.bleepingcomputer.com/forums/t/232731/usps-virus-email-infected-my-computer/

Thanks for your help.



That is fine. Thank you.

Hello,

Now that you have posted a log here: http://www.bleepingcomputer.com/forums/t/232731/usps-virus-email-infected-my-computer/ 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 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 a while to get a response but your log will be reviewed and answered as soon as possible

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