Hello,

 

I think I might be infected with virus or something alike.

I'm using Avira antivirus program, win7 enterprise.

Avira was alerting me about stopping some virus and after scan it apparently removes it. Thou that happened few times.

After that I got suspicious and looked at task manager and found some weird named processes.

Since Avira said everything is fine I tried malwarebytes quick scan and it returned with some random Trojan (that it removed and it never reappears on other quick scans )syshost (google search says it supposed to be a virus) and kmservice (google on later one confirmed it to be ms office crack, so its ok).

Malwarebytes did try to remove syshost but apparently Avira prevented it on pc restart, so now its in quarantine, but I think that the virus got back since it wasn't removed from registry.

 

So all in all help me to determine if im infected or not.

Hi,

 

Is it spelt syshost or svchost?

 

Please open any files in these locations (replace <USERNAME> with the name of the user which you ran the Malwarebytes scan in), and copy and paste the contents into your next reply:

  • Windows 2000 & Windows XP:
    C:\Documents and Settings\<USERNAME>\Application Data\Malwarebytes\Malwarebytes' Anti-Malware\Logs
  • Windows Vista & Win7:
    C:\Users\<USERNAME>\AppData\Roaming\Malwarebytes\Malwarebytes' Anti-Malware\Logs

Hi,

 

Just making sure, the file name can change a lot of things. Thank you for that log, looks like we will need some tools to remove this which are not allowed in this section.

 

Please follow the instructions in THIS GUIDE starting at Step 6. If you cannot complete a step, skip it and continue.

Once the proper logs are created (make sure to include the combofix log created, probably located at C:\ComboFix.txt), then make a NEW TOPIC and post it HERE. Please include a description of your computer issues, what you have done to resolve them, and a link to this topic.

If you can produce at least some of the logs, then please create the new topic and explain what happens when you try to create the log(s) that you couldn't get. If you cannot produce any of the logs, then still post the topic and explain that you followed the Prep. Guide, were unable to create the logs, and describe what happens when you try to create the logs.

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.

If HelpBot replies to your topic, PLEASE follow Step One so it will report your topic to the team members.

I have created a thread:

http://www.bleepingcomputer.com/forums/t/526918/syshost/

 

As I wrote in thread I didn't quite get if you wanted me to ue combofix, but since it's such a scary program I did only use dds as in guide you linked.

Hi,

 

Seriously sorry about that, I forgot to edit my instructions. Good on you for not running combofix, and I'm so sorry for the confusion. Combofix isn't scary if you know what you are doing, but still it shouldn't be run unless a trained helper requests it.

Hello,

Now that you have posted your log, 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 MRT 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 MRT 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 MRT 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 MRT 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 MRT Team member is already assisting you and not open the thread to respond.

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

If HelpBot replies to your topic, PLEASE follow Step One so it will report your topic to the team members.

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

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