Question
QUESTION: Hi Brian, everyday my firewall sends an alert about blocking Malware MyDoom. Is there something I need to do?

ANSWER: Hi Elizabeth

MyDoom is a virus which sends out spam emails from infected computers.  Chances are, your firewall is trying to prevent this outgoing activity from your PC.  Let's try and get you cleaned up.  Start by running a Malwarebytes Anti-Malware scan, preferably in safe mode, then post me that log and a HijackThis log, and we'll see where that takes us.

Restart the computer in Safe Mode by continuously tapping the F8 key on boot until a black screen with a menu appears.  Choose to Start Windows in Safe Mode with Networking.  Log on as usual.  

Please download Malwarebytes' Anti-Malware to your desktop from here:

http://www.besttechie.net/tools/mbam-setup.exe

Double-click mbam-setup.exe and follow the prompts to install the program.
* At the end, be sure a checkmark is placed next to
o Update Malwarebytes' Anti-Malware
* then click Finish.
* If an update is found, it will download and install the latest version.
*Run a Full Scan.
* When the scan is complete, click OK, then Show Results to view the results.
* Be sure that everything is checked, and click Remove Selected.
* When completed, a log will open in Notepad.  Save that log and reboot normally.

Download and install HijackThis:

http://www.trendsecure.com/portal/en-US/_download/HJTInstall.exe

Make sure you close EVERY open window and ALL browser windows. The only thing that should be open is the HijackThis program.
Double-click on the file you just downloaded.
Click on the "Install" button.
Upon install, HijackThis should open for you.
Should it not open, go to C:\Program Files\Trend Micro\HijackThis and double click on HijackThis.exe
Choose 'Do a system scan and save a log file'.
Copy the text file which opens in Notepad and paste it in your follow-up, along with the Malwarebytes log.
* Do not fix any entries in HijackThis, as they may be harmless.

Answer
Hi Elizabeth

Your HJT log file is clean, and happily enough, so is your MBAM log.  No threats were found.  So we have to ask why the firewall is giving you these warnings.  My best guess is that your firewall is properly monitoring traffic on the network and is blocking activity on ports associated with Mydoom, especially the inbound TCP ports for the backdoor Trojan component of the virus.  In other words, the firewall is doing it's job by blocking probes on ports associated with MyDoom.  Unless you have other computers on your network, do not worry about these probes, as they are common.  If you have further questions or concerns, just let me know.  Cheers!

Brian
