I've become a bit paranoid ever since my laptop contracted the ave.exe virus a few months ago and which I managed to clear.

I'm running Windows Vista (32) and have Virgin Media's anti-virus program installed.

I occasionally get a Firewall message with the following but don't know if it is legitamate or someone trying to take control of my machine (or trying to take control of another FROM my machine!!):

=====
The following program is attempting to connect to the Internet or the network.

Name: Windows host process (Rundll32)
Publisher: Not digitally signed
Company: Microsoft Corporation
Version: 6.0.6000.16386
Path: C:\Windows\systems32\rundll32.exe

Connection Details
Protocol: TCP/outbound
Remote IP: 65.55.7.141
Host name: (no host name found)
Remote port: 80 (World Wide Web HTTP)
=====

I have an option to Allow, Allow once (which I usually select) and Block.

According to allnettools, the above ip address alledgedly belongs to none other than:

=====
65.52.0.0 - 65.55.255.255
Microsoft Corp
One Microsoft Way
Redmond, WA
US


Microsoft Corporation
noc@microsoft.com
+1-425-882-8080
=====

Shall I click Allow or should I Block it?

I advise Blocking..
Windows\systems32\rundll32.exe <-- your entry
Windows\System32\rundll32.exe <-- valid Windows entry,notice your entry says system(s)32. Unless you typed that wrong it would indicate malware.

What is rundll32.exe And Why Is It Running?


Please run TFC by OT
Please download TFC by Old Timer and save it to your desktop.
alternate download linkSave any unsaved work. TFC will close ALL open programs including your browser!
Double-click on TFC.exe to run it. If you are using Vista, right-click on the file and choose Run As Administrator.
Click the Start button to begin the cleaning process and let it run uninterrupted to completion.
Important! If TFC prompts you to reboot, please do so immediately. If not prompted, manually reboot the machine anyway to ensure a complete clean.
Next run MBAM (MalwareBytes):

Please download Malwarebytes Anti-Malware (v1.46) and save it to your desktop.alternate download link 1
alternate 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.
  • 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.

How do I get help? Who is helping me?For the time will come when men will not put up with sound doctrine. Instead, to suit their own desires, they will gather around them a great number of teachers to say what their itching ears want to hear....Become a BleepingComputer fan: Facebook

Thank you for your swift reply.

I have checked and it was a typo by me. The actual path certainly is: Windows\System32\rundll32.exe.

Should I still block or allow?
