Virus Total link

This was just lying around in the temp folder, don't know what it does but it's there. After doing a search, I found that there was another file called "wtf2481.tmp", which also had the same detections as my "wtfCFDB.tmp" file.

 

Does anyone know these tmp files get to your PC? Sorry if these kinds of questions are not allowed.

Have you used any security programs to find and remove malware? The link for VT certainly identifies the file as malware.

Where it came from....most likely from using a P2P program.

 

Scan using the programs below.

 

Download Emsisoft Emergency Kit and save it to your desktop. Double click on EmsisoftEmergencyKit.exe to extract its contents and create a shortcut on the desktop. Leave all settings as they are and click  Accept & Extract. A folder named EEK will be created in the root of the drive (usually c:\). .

  • After extraction an Emsisoft Emergency Kit window will open. Under "Run Directly:" click Emergency Kit Scanner.
  • When asked to run an online update, click Yes.
  • When the update is finished, click the Back to Security Status link in the left corner. On the main screen click the Scan Now button.
  • Select the malware scan option and click the SCAN button.
  • When the scan is finished click the Quarantine selected objects button. Note, this option is only available if malicious objects were detected during the scan.
  • Click the View Report button and in the Reports window double-click on the most recent log. Note, logs are named as follows: a2scan_<date>-<time>.txt.
  • Copy/paste the report contents in your next reply.

 

Download Malwarebytes' Anti-Malware from Here

Double-click mbam-setup-2.X.X.XXXX.exe to install the application (X's are the current version number).

  • Make sure a checkmark is placed next to Launch Malwarebytes' Anti-Malware, then click Finish.
  • Once MBAM opens, when it says Your databases are out of date, click the Fix Now button.
  • Click the Settings tab at the top, and then in the left column, select Detections and Protections, and if not already checked place a checkmark in the selection box for Scan for rootkits.
  • Click the Scan tab at the top of the program window, select Threat Scan and click the Scan Now button.
  • If you receive a message that updates are available, click the Update Now button (the update will be downloaded, installed, and the scan will start).
  • When MBAM is finished scanning it will display a screen that displays any malware that it has detected.
  • Click the Remove Selected button.
  • MBAM will now delete all of the files and registry keys and add them to the programs quarantine. When removing the files, MBAM may require a reboot in order to remove some of them. If it displays a message stating that it needs to reboot, please allow it to do so.
  • While still on the Scan tab, click the link for View detailed log, and in the window that opens click the Export button, select Text file (*.txt), and save the log to your Desktop.
  • The log is automatically saved by MBAM and can also be viewed by clicking the History tab and then selecting Application Logs.

POST THE LOG FOR  REVIEW.

 

  • Hold down Control and click on this link to open ESET OnlineScan in a new window.
  • Click the esetonlinebtn.png button.
  • For alternate browsers only: (Microsoft Internet Explorer users can skip these steps)
  • Click on esetsmartinstaller_enu.exe to download the ESET Smart Installer. Save it to your desktop.
  • Double click on the esetsmartinstaller_enu.png icon on your desktop.
  • Check "YES, I accept the Terms of Use."
  • Click the Start button.
  • Accept any security warnings from your browser.
  • Under scan settings, check "Scan Archives" and "Remove found threats"
  • ESET will then download updates for itself, install itself, and begin scanning your computer. Please be patient as this can take some time.
  • When the scan completes, click List Threats
  • Click Export, and save the file to your desktop using a unique name, such as ESETScan. Include the contents of this report in your next reply.
  • Click the Back button.
  • Click the Finish button.
  • NOTE:Sometimes if ESET finds no infections it will not create a log.

VirusTotal identifies it as a Windows executable (a dll). As malware goes it's old, it was first submitted to VT in 2008.

 

Is the file still in your temp folder?
