I used ComboFix a several times on my machines. Now I had some troubles with my laptop, so I tried to use Combofix. It crashes at the start. The little green indicator fills up and a message says something like "Cannot open the file, you might not have the permissions to it" In the blue bar stays 32788R22FWJFW\iexplore.exe or 32788R22FWJFW\Hidec.exe 32788R22FWJFW\n.pif. It pops up like a 25 times. Than it says can't open nircmd.cfxxe

I ran hijackthis checkt it on hijacthis.de, checkt for virusses with Avg, sophos online scan and Eset online scan. It removed some crap, but Combofix still doesn't work.

What is going on here?

Sorry for bad english

There are circumstances ComboFix will hang or stall at various stages due to malware interference, failure to disable any other real-time protection tools and CD Emulators (Daemon Tools, Alchohol 120%, Astroburn, AnyDVD) so that it does not complete successfully. While that is not normal behaviour, it is not unusual.

Please note the message text in blue at the top of the Am I infected? What do I do? forum.

No one should be using ComboFix unless specifically instructed to do so by a Malware Removal Expert who can interpret the logs. Please read the pinned topic ComboFix usage, Questions, Help? - Look here.

I ran hijackthis checkt it on hijacthis.de,

HijackThis is an advanced enumerator (similar in some respects to a registry editor) that is used to display certain areas of the Windows registry where the majority of malware reside. HijackThis will scan these areas of your system and then create a log to help diagnose the presence of undetected malware in known hiding places. However, since HijackThis only scans certain areas of your system/registry, a hijackthis log may not always show all the malware on your system. Most of the log entries are required to run a computer and removing essential ones can potentially cause serious damage such as loss of Internet connectivity or problems with your operating system which could preventing it from starting. Using HijackThis requires advanced knowledge about the Windows Operating System and relies on trained experts to interpret the log entries and investigate them in order to determine what needs to be fixed.

Online HijackThis analyzers work in a similar manner but rely on the user's ability to interpret the results and determine what needs to be fixed. However, they often provide misleading and/or questionable results. In my experience, they DO NOT always identify all the malware or all the files properly. They sometimes list legitimate files as bad and bad files as legitimate. They sometimes show entries with no file (file missing) as bad when that is not always the case. Although these sites are open to the public, the user needs to know what they are doing and how to research the displayed log entries before using the original HijackThis application to fix anything.

If you do not have advanced knowledge about computers or training in malware investigation, you should NOT rely on the results of online analyzers or attempt to fix anything without consulting an expert. Doing so on your own and using HijackThis incorrectly could adversely impact your system.

Thanks for your answer. I understand what you mean. I'v enough expierence to use CF.

My laptop is running slow at some times and I tried to run some cleaners, but nothing will solve the problem. I use normally Malwarebytes Antimalware, but this will not update anymore. I seriously think I've some bad infections, but can't clean it.

Some infections are difficult to remove completely because of their morphing characteristics which allows the malware to regenerate itself. Sometimes there is hidden piece of malware (i.e. rootkit) which has not been detected by your security tools that protects malicious files and registry keys so they cannot be permanently deleted. Other types of malware can even terminate your security tools by changing the permissions on targeted programs so that they cannot run or complete scans. Disinfection will probably require the use of more powerful tools than we recommend in this forum. Before that can be done you will need you to create and post a DDS/HijackThis log for further investigation.

Please read the pinned topic titled "Preparation Guide For Use Before Posting A Hijackthis Log". If you cannot complete a step, then skip it and continue with the next. In Step 6 there are instructions for downloading and running DDS which will create a Pseudo HJT Report as part of its log.

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. 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.

Today somebody told me today that if I send him an email to his Live address, his computer says it could be unsafe. I know nothing about that...

Hello,

Now that you have posted a log here: http://www.bleepingcomputer.com/forums/t/292654/infected-with-unknown-malwarevirus/ 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.
