The PC doesn't start in normal mode (it freeze at the boot screen), I have attached the log file made by combofix in safe mode: Attached File  ComboFix.txt   422.39KB   5 downloads
At the start of the scan appears:
SED: can't read nt-osSvcDump00: No such file or directory
SED: can't read nt-osSvcDump00: No such file or directory

The two files removed by ComboFix reappear after some times.

Isn't that happened to anyone?
What means these "SED" errors?

EDIT: I noticed that the virus set almost all Windows services to Disabled, I have changed most of them to Manual but after a while they are still set to Disabled.

Hello

While we understand your frustration at having to wait, please note that Bleeping Computer deals with several hundred requests for assistance such as yours on a daily basis. As a result, our backlog is quite large as are other comparable sites that help others with malware issues. Although our HJT Team members work on hundreds of requests each day, they are all volunteers who work logs when they can and are able to do so. No one is paid by Bleeping Computer for their assistance to our members.

Further, our malware removal staff is comprised of team members with various levels of skill and expertise to deal with thousands of malware variants, some more complex than others. Although we try to take DDS/HJT logs in order (starting with the oldest), it is often the skill level of the particular helper and sometimes the operating system that dictates which logs get selected first. Some infections are more complicated than others and require a higher skill level to remove. Without that skill level attempted removal could result in disastrous results. In other instances, the helper may not be familiar with the operating system that you are using, since they use another. In either case, neither of us want someone to assist you who is not familiar with your issue and attempt to fix it.

We ask that once you have posted your log and are waiting, please DO NOT "bump" your thread or make further replies until it has been responded to by a member of the HJT Team. The reason we ask this or do not respond to your requests is because that would remove you from the active queue that Techs and Staff have access to. The malware 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.

That is why I have made an edit to your last post, instead of a reply. Please do not multiple post here, as that only pushes you further down the queue and causes confusion to the staff.

Please be patient. It may take a while to get a response but your log will be reviewed and answered as soon as possible.

Thank you for understanding.

Hello ale5000

Welcome to Welcome to BleepingComputer :thumbup2:
=====================
  • Download OTL to your desktop.
  • Double click on the icon to run it. Make sure all other windows are closed and to let it run uninterrupted.
  • When the window appears, underneath Output at the top change it to Minimal Output.
  • Under the Standard Registry box change it to All.
  • Check the boxes beside LOP Check and Purity Check.
  • Click the Run Scan button. Do not change any settings unless otherwise told to do so. The scan wont take long.
  • When the scan completes, it will open two notepad windows. OTListIt.Txt and Extras.Txt. These are saved in the same location as OTListIt2.
  • Please copy (Edit->Select All, Edit->Copy) the contents of these files, one at a time, and post it with your next reply.
===========
Download This file. Note its name and save it to your root folder, such as C:\.
  • Disconnect from the Internet and close all running programs.
  • Temporarily disable any real-time active protection so your security program drivers will not conflict with this file.
  • Click on this link to see a list of programs that should be disabled.
  • Double-click on the downloaded file to start the program. (If running Vista, right click on it and select "Run as an Administrator")
  • Allow the driver to load if asked.
  • You may be prompted to scan immediately if it detects rootkit activity.
  • If you are prompted to scan your system click "Yes" to begin the scan.
  • If not prompted, click the "Rootkit/Malware" tab.
  • On the right-side, all items to be scanned should be checked by default except for "Show All". Leave that box unchecked.
  • Select all drives that are connected to your system to be scanned.
  • Click the Scan button to begin. (Please be patient as it can take some time to complete)
  • When the scan is finished, click Save to save the scan results to your Desktop.
  • Save the file as Results.log and copy/paste the contents in your next reply.
  • Exit the program and re-enable all active protection when done.

Thanks for the help but I have discovered that there was also a hardware problem that also forced me to reinstall windows so the problem is fixed now.

Great that for letting us know.

The following are some articles and a Windows Update link that I like to suggest to people to prevent malware and general PC maintenance.

Windows Updates - It is very important to make sure that both Internet Explorer and Windows are kept current with the latest critical security patches from Microsoft. To do this just start Internet Explorer and select Tools > Windows Update, and follow the online instructions from there.

Prevention article To find out more information about how you got infected in the first place and some great guidelines to follow to prevent future infections please read the Prevention artice by Miekiemoes.

If your computer is slow Is a tutorial on what you can do if your computer is slow.


Since this issue appears to be resolved ... this Topic has been closed. Glad we could help. :thumbup2:
