I found this forum while surfing the web to find a way to clean my daughter’s PC of some rather persistent malware she inadvertently downloaded last week. It appeared she initially download Personal Antivirus. On one of my other clean PCs I discovered Malwarebytes and after some difficulty was able to get that running. I had to rename it to get it to run and then run in safe mode. I believe I corrected that problem, but there are still a number of other issues that Malwarebytes finds but cannot delete. After Malwarebytes finds the problems it says that several files will be deleted when I restart the PC. However, when I start the PC in normal mode, it eventually hangs and therefore apparently cannot complete the removal.

The problem I have appears to be with uacinit.dll. Before posting I read several posts that addressed this issue and I am afraid I may have to reformat her PC and reinstall the operating system. I am hoping for the best (I can successfully clean her PC without reformatting), but preparing for the worse. Her PC is an HP Pavilion a1030e with XP Professional.

I have logs from the last two times I ran Malwarebytes which I will post below.

Another bizarre thing that happens after she starts up her PC is that the audio from a number of websites start playing without opening Internet Explorer. However, when I do open IE, it asks me if I want to return to a previous session or start on my homepage. If I open the previous session anywhere from 8 to 20 windows open up running either commercials or odd videos. One website I remembered opening was Cranky Geeks. I am thinking this browser hijack is related to the malware problem.

The Malwarebytes logs are posted below. I got the first one when I ran Malwarebytes in safe mode and the second when I ran it in normal mode. Thanks very much for helping

You have a nasty rootkit
Lets see if you can run this:

We Need to check for Rootkits with RootRepeal
  • Download RootRepeal from the following location and save it to your desktop.
  • Extract RootRepeal.exe from the archive (If you did not use the "Direct Download" mirror).
  • Open Posted Image on your desktop.
  • Click the Posted Image tab.
  • Click the Posted Image button.
  • Check all seven boxes: Posted Image
  • Push Ok
  • Check the box for your main system drive (Usually C:), and press Ok.
  • Allow RootRepeal to run a scan of your system. This may take some time.
  • Once the scan completes, push the Posted Image button. Save the log to your desktop, using a distinctive name, such as RootRepeal.txt. Include this report in your next reply, please.

Thanks for the quick reply Garmanma! I downloaded RootRepeal last night and ran it on my daughter's PC. I ran it overnight in normal mode but I was not sure if it fully completed, because it appeared to stop but it still said "scanning" just above the "Scan" button. However, a report was generated so I saved it. This morning I ran RootRepeal in safe mode and that did complete successfully. I saved that report and will post both the normal mode and safe mode rerpots below. I noticed that when RootRepeal ran is safe mode, it found several more items than when it ran in normal mode.

My daughter's PC is rebooting very slowly and about 30% of the reboots end up with the PC freezing after it appears to have started correctly; that is, I can't open anything and eventually when I click on something I hear a "beep" and the cursor freezes. At that point I have to shut off the power at the power bar, turn it on and then restart the PC. I suppose that is a result of the malware in the PC.

Again, thanks for your help.

Unless otherwise specified, scans should be run in normal mode for best results

Now that you were able to produce a log you need to post it in our HJT forum:
http://www.bleepingcomputer.com/forums/f/22/virus-trojan-spyware-and-malware-removal-logs/
Give a brief description and tell them that this log was all you could get to run successfully
The HJT team is extremely busy, so be patient and good luck

Hello,

Now that you have posted a log here: http://www.bleepingcomputer.com/forums/t/257404/my-daughters-pc-has-malware-rootkit/ 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.
