I have a Trojan.agent that continues to return. I have run MWB and it will find it and delete it on re-boot but the funny thing is when I scan again it will be gone. 20 min later when I scan it will be back. If I run MWB in safe mode and re-boot in safe mode the Trojan never returns after several scans. I have restore turned off.

I have also run Superantispy and it found nothing. I have also run several other clean tools and they found nothing as well.

Let me know what you think.

Please download and scan with Dr.Web CureIt.
alternate download link
Follow these instructions for performing a scan in "safe mode".
If you cannot boot into safe mode, then perform your scan in normal mode. Be aware, this scan could take a long time to complete.

It appears the operation of Dr.Web CureIt are not exactly how the instructions indicate however the log is below.

I ran another MWB and you can see it is different.

Your Malwarebytes Anti-Malware log indicates you are using an outdated database version. Please update it through the program's interface (preferable method) or manually download the definition updates and just double-click on mbam-rules.exe to install. Then perform a new Quick Scan in normal mode and check all items found for removal. Don't forgot to reboot afterwards. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware. When done, click the Logs tab and copy/paste the contents of the new report in your next reply.

Your database shows 1971. Last I checked it was 1981.

Mbam-rules.exe is not updated daily. Another way to get the most current database definitions if you're having problems updating, is to install MBAM on a clean computer, launch the program, update through MBAM's interface, copy the definitions (rules.ref) to a USB stick or CD and transfer that file to the infected machine. Copy rules.ref to the location indicated for your operating system. If you cannot see the folder, then you may have to Reconfigure Windows to show it.

That's weird since I have the paid version of that program and it is set to update on its own once a day.

Anyway I updated it manually and it went to version 1982. Did several scans and it seems to be GTG now. I will let you know if something changes.

Thanks again for all you guys do.

You're welcome.

If there are no more problems or signs of infection, you should Create a New Restore Point to prevent possible reinfection from an old one. Some of the malware you picked up could have been backed up, renamed and saved in System Restore. Since this is a protected directory your tools cannot access to delete these files, they sometimes can reinfect your system if you accidentally use an old restore point. Setting a new restore point AFTER cleaning your system will help prevent this and enable your computer to "roll-back" to a clean working state.

The easiest and safest way to do this is:
  • Go to Start > Programs > Accessories > System Tools and click "System Restore".
  • Choose the radio button marked "Create a Restore Point" on the first screen then click "Next". Give the R.P. a name, then click "Create". The new point will be stamped with the current date and time. Keep a log of this so you can find it easily should you need to use System Restore.
  • Then use Disk Cleanup to remove all but the most recently created Restore Point.
  • Go to Start > Run and type: Cleanmgr
  • Click "Ok". Disk Cleanup will scan your files for several minutes, then open.
  • Click the "More Options" tab, then click the "Clean up" button under System Restore.
  • Click Ok. You will be prompted with "Are you sure you want to delete all but the most recent restore point?"
  • Click Yes, then click Ok.
  • Click Yes again when prompted with "Are you sure you want to perform these actions?"
  • Disk Cleanup will remove the files and close automatically.
Vista Users can refer to these links: Create a New Restore Point and Disk Cleanup.

Tips to protect yourself against malware and reduce the potential for re-infection:Avoid gaming sites, pirated software, cracking tools, keygens, and peer-to-peer (P2P) file sharing programs. They are a security risk which can make your computer susceptible to a smörgåsbord of malware infections, remote attacks, exposure of personal information, and identity theft. Many malicious worms and Trojans spread across P2P file sharing networks, gaming and underground sites. Users visiting such pages may see innocuous-looking banner ads containing code which can trigger pop-up ads and malicious Flash ads that install viruses, Trojans and spyware. Ads are a target for hackers because they offer a stealthy way to distribute malware to a wide range of Internet users. The best way to reduce the risk of infection is to avoid these types of web sites and not use any P2P applications. Read P2P Software User Advisories and Risks of File-Sharing Technology.

Keeping Autorun enabled on USB (pen, thumb, jump) and other removable drives has become a significant security risk due to the increasing number of malware variants that can infect them and transfer the infection to your computer. To learn more about this risk, please read:Many security experts recommend disabling this feature as a method of prevention. Microsoft recommends doing the same.

...Disabling Autorun functionality can help protect customers from attack vectors that involve the execution of arbitrary code by Autorun when inserting a CD-ROM device, USB device, network shares, or other media containing a file system with an Autorun.inf file...
