For a couple of months now, ever since I upgraded to AVG 2011 from AVG 2010, it keeps coming up with a warning that malware C:\Windows\System32\CTRESTRT.EXE has been detected. This warning pops up everyday about an hour after turning the computer on. I am running with Windows 7. I have tried scanning the computer with Malware Bytes Anti-Malware, Spybot Search and Destroy, and HiJackThis. None of these programs find anything. I tried uninstalling AVG and installed Avast, Avast didn't find anything either. I redownloaded AVG 2011 and once again every day about an hour after turning on the computer the warning pops up. I ran AUTORUNS and found nothing out of the ordinary. There has been no noticeable problems on the computer, no ad-bombing, blue screens, nothing. I am at a complete loss. Any help would be appreciated.

When moving to the vault AVG reports the following:

Process Terminated: cmd.exe CTRESTRT.EXE
Files Deleted: CTRESTRT.BAT CTRESTRT.EXE

Hello, This is possibly a False positive. We should double check it before we take action.

Lets' upload this file for a second opinion on what it actually is..

Please make sure that you can view all hidden files. Instructions on how to do this can be found here:
How to see hidden files in Windows

Please click this link-->Jotti

When the jotti page has finished loading, click the Browse button and navigate to the following file and click Submit.
<filepath>suspect.file

Please post back the results of the scan in your next post.

If Jotti is busy, try the same at Virustotal: http://www.virustotal.com/


NOTE:
For submission to a specific anti-virus vendor see Submitting Virus Samples: How to Submit a Virus.


We can also run an online scan
Please perform a scan with Kaspersky Online Virus Scanner.
-- Requires free Java Runtime Environment (JRE) to be installed before scanning for malware as ActiveX is no longer being used.
-- This scan will not remove any detected file threats but it will show where they are located so they can be cleaned with other tools.
  • Vista users need to right-click the IE or FF Start Menu or Quick Launch Bar icons and Run As Administrator from the context menu.
  • Read the "Advantages - Requirements and Limitations" then press the Posted Image... button.
  • You will be prompted to install an application from Kaspersky. Click the Run button. It will start downloading and installing the scanner and virus definitions.
  • When the downloads have finished, you should see 'Database is updated. Ready to scan'. Click on the Posted Image... button.
  • Make sure these boxes are checked. By default, they should be. If not, please check them and click on the Posted Image... button afterwards:
    • Detect malicious programs of the following categories:
      Viruses, Worms, Trojan Horses, Rootkits
      Spyware, Adware, Dialers and other potentially dangerous programs
    • Scan compound files (doesn't apply to the File scan area):
      Archives
      Mail databases
  • Click on My Computer under the Scan section. OK any warnings from your protection programs.
  • The scan will take a while so be patient and do NOT use the computer while the scan is running. Keep all other programs and windows closed.
  • Once the scan is complete (the 'status' will show complete), click on View Scan Report and any infected objects will be shown.
  • Click on Save Report As... and change the Files of type to Text file (.txt)
  • Name the file KAVScan_ddmmyy (day, month, year) before clicking on the Save button and save it to your Desktop.
  • Copy and paste (Ctrl+C) the saved scan results from that file in your next reply.
-- Note: Some online scanners will detect existing anti-virus software and refuse to cooperate. You may have to disable the real-time protection components of your existing anti-virus and try running the scan again. If you do this, remember to turn them back on after you are finished.
