Hi I'm not an expert so please bear with me. I've got a Mutimedis PC with Windows Vista (not professional), connected via wireless link to a home network, one other (Sony Vaio) connected to the network, hard wired. The PC seems infected, since yesterday afternoon the Start Menu appears randomly and flickers or flashes, as does the Caps lock light. I cannot enter anything into the browser windows as the PC keeps bringing up the shortcuts for that key, printing menu if I hit "P", etcetera. When I reboot the PC it starts up in "F" mode, although I can turn that light off by pressing the key again, I cannot stop the start menu coming up every few seconds nor the Caps lock to stop randomly triggering every few seconds and as soon as I try to type anything. I looked into the processes, the limit of my technical knowledge, and found a couple of (I think) suspect processes running, not attributed to System or me, including cssrs.exe, ati2Evxx.exe, unsecapp.exe, winlogon.exe, and rundll32.exe, I think the first is a known Trojan from what I could look up online? I had McAfee running at the time I got infected, several McAfee "scans" have turned up nothing. I am using the laptop to type as the PC is totally unusable although it boots up and shuts down ok for now, and I can open up the internet browser. I can point and click but cannot type anything in, neither in Word nor web addresses in the browser, please can you bear this in mind and help with advice as to how to get logs of activity to you directly from the PC without having to type anything, if you need them- for this reason I could not run the DDS, as instructed for new users with a malware problem, as I cannot type the login for this user account from that PC to attach it with this mail. So far, whatever it is has not affected the laptop but I am completely stuck! (And wondering how this got onto my PC with McAfee running?!) Thank you!!

cssrs.exe, ati2Evxx.exe, unsecapp.exe, winlogon.exe are legitimate processes as long as they are in the proper location
You said you have 2 Computers. Do you have a thumb drive or the ability to burn a CD?
You can run these tools
First:

------------------------------------


The process of cleaning your computer may require you to temporarily disable some security programs. If you are using SpyBot Search and Destroy, please refer to Note 2 at the bottom of this page.

Please download Malwarebytes Anti-Malware and save it to your desktop.
alternate download link 1
alternate download link 2
  • 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 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 and exit MBAM.
Note:
-- If MBAM encounters a file that is difficult to remove, you may be asked to reboot your computer so it can proceed with the disinfection process. Regardless if prompted to restart the computer or not, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.

Note 2:
-- MBAM may make changes to your registry as part of its disinfection routine. If you're using other security programs that detect registry changes (like Spybot's Teatimer), they may interfere with the fix or alert you after scanning with MBAM. Please disable such programs until disinfection is complete or permit them to allow the changes. To disable these programs, please view this topic: How To Temporarily Disable Your Anti-virus, Firewall And Anti-malware Programs
