Hello,

My wife is having problems with her laptop running Vista Home Premium with Trend Micro anti-virus software. I usually don't use this machine, but it is running very slow and there are programs/processes I don't recognize. The problem started on Dec 27th (Sunday). I noticed the following observations while troubleshooting. First, when booting the computer, I get a Windows message box stating it doesn't know which program to use to start the ~TM3F69.tmp file. The box asks if I want to search the net or manually select a program to run that file. I just close out of this box. Second, I noticed the following program running in the taskmanager window-- sr882388.exe. I was suspicious because it was loaded on Dec 27th, and it was hogging about 50% of CPU useage. I simply ended the the process which restored CPU useage. I also noticed a svchost.exe using a lot of CPU processing, so I ended that process as well. Although I'm able to free up CPU useage by ending these 2 processes in taskmanager, the solution is not permanent. When I shut down, the problems resurface upon boot-up. Fourth, I noticed the following program on the desktop-- fjhdyfhsn.bat. I simply banished that to the recycle bin. Finally, I am unable to turn on the Security Center. I go to the Control Panel and select Security Center. When, I try to turn it on, Windows tells me it is unable. I use the MS Firewall in lieu of the Trend Micro Firewall. Before I go deleting files and stuff, I need some deeper technical advise beyond what I am capable of myself. Thanks in advance.....

Hello.. Download,install and update these. Before running End those processes in Task Manager. Now disconnect from the internet and run the 2 scans
Next run MBAM (MalwareBytes):

NOTE: Before saving MBAM please rename it to zztoy.exe....now save it to your desktop.

Please download Malwarebytes Anti-Malware and save it to your desktop.

alternate download link

MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you. Temporarily disable such programs or permit them to allow the changes.
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
MBAM will automatically start and you will be asked to update the program before performing a scan.
  • If an update is found, the program will automatically update itself. Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the definition updates, manually download them from here and just double-click on mbam-rules.exe to install.
On the Scanner tab:
  • Make sure the "Perform Quick Scan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
Back at the main Scanner screen:
  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply. Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.
  • Exit MBAM when done.
Note: If MBAM encounters a file that is difficult to remove, you will be asked to reboot your computer so MBAM can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.


We Need to check for Rootkits with RootRepeal
  • Download RootRepeal from the following location and save it to your desktop.
  • Extract RootRepeal.exe from the archive (If you did not use the "Direct Download" mirror).
  • Open Posted Image on your desktop.
  • Click the Posted Image tab.
  • Click the Posted Image button.
  • Check all seven boxes: Posted Image
  • Push Ok
  • Check the box for your main system drive (Usually C:), and press Ok.
  • Allow RootRepeal to run a scan of your system. This may take some time.
  • Once the scan completes, push the Posted Image button. Save the log to your desktop, using a distinctive name, such as RootRepeal.txt. Include this report in your next reply, please.

I'm having problems understanding the instructions provided, so I want to be sure I've got them right before I proceed.

First, I should boot up my computer and NOT end the processes I think are malware or viruses.

Second, I need to download and update MBAM (MalwareBytes) and RootRepeal.

Third, after downloading and installing those 2 programs, I need to disconnect from the internet

Fourth, I need to run the MBAM program and attach the report to my next post.

Fifth, I need to run the RootRepeak program and attach the report in my next post.

Just wanna make sure I'm doing this right.

Here is the Malware report log. I wan it twice and both logs are here.I was unable to get a log for the RootRepeal program. I ran it for nearly 40 hours and seemed to be stuck. The Malware program seemed to find some stuff and eliminate it; however, I'm still unable to open the MS Security Center.

  • Disconnect from the Internet and close all running programs.
  • Temporarily disable any real-time active protection so your security programs will not conflict with gmer's driver.
  • Double-click on the randomly named GMER file (i.e. n7gmo46c.exe) and allow the gmer.sys driver to load if asked.
  • Note: If you downloaded the zipped version, extract the file to its own folder such as C:\gmer and then double-click on gmer.exe.

    Posted Image
