Hi, I am worried that my personal laptop may be monitored and as I was looking around I found two processes running that I am worried about. First, two instances of rundll32.exe with no username or file association that I get an access denied error when I try to kill. (I am running as administrator) and csrss.exe.

What can I do to fix these two and also to scan my pc and be sure that I'm not being hacked/monitored/etc?

Please download Malwarebytes Anti-Malware (v1.46) and save it to your desktop.Download Link 1
Download Link 2
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.
    For instructions with screenshots, please refer to the How to use Malwarebytes' Anti-Malware Guide.
  • 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.Most of the processes in Task Manager will be legitimate as shown in these links.Determining whether a file is malware or a legitimate process usually depends on the location (path) it is running from. One of the ways that malware tries to hide is to give itself the same name as a critical system file like svchost.exe. However, it then places itself in a different location (folder) than where the legitimate file resides and runs from there. Another techinique is for the process to alter the registry and add itself as a Startup program or service so that it can run automatically each time the computer is booted. Keep in mind that a legitmate file can also be infected by some types of malware such as Virut which is a dangerous polymorphic file infector. A file's properties may give a clue to identifying it. Right-click on the file, choose Properties and examine the General and Version tabs.

Tools to investigate running processes and gather additional information to identify them and resolve problems:These tools will provide information about each process, CPU usage, file description and its path location.

Anytime you come across a suspicious file or one that you do not recognize, search the name using Google <- click here for an example.

Or search the following databases:If you cannot find any information, the file has a legitimate name but is not located where it is supposed to be, or you want a second opinion, submit it to Jotti's virusscan or VirusTotal. In the "File to upload & scan" box, browse to the location of the suspicious file and submit (upload) it for scanning/analysis.
