Lost Internet

Hi,

I was surfing on the net with several browser windows open when my Avast antivirus popped up a warning. It advised of a reboot scan which I did. When it was done I received a warning that: Avast! will not be able to protect mail/news (error100050) Please check that Avast service (AvastSvc.exe) is not blocked by your personal firewall. My wire less network says that it is acquiring a network address.I made sure my laptop would connect to the internet.

In Avast my real time shields are off and I can't turn it on. I tried malwarebytes without an update and that didn't work. I tried to use a restore point but that doesn't work. I went on line with my laptop and searched the avast issue and did your read and run for maleware. Here are my logs.

Thank you in advance for your help.

 

Last of my logs

 

I Ran MRBCheck and TDSSKiller and have the logs. I also uninstalled Avast but I still can't connect to my wireless router. Says acquiring network address.

Thank you for you help.

 

Hi Rick1ms,

I will help you with your remaining malware problems as chaslang has been busy.

========WARNING========
The below is specifically for Rick1ms's computer

Attached is afd.zip

Inside is:

• afd.reg
• fixme+restart.bat

Extract both files to the infected computer's desktop.

First double-click afd.reg and allow it to merge into the registry. You should receive a successful message.

Now reboot your PC.

Once you have rebooted...

Test your internet, If it still is not working, run the fixme+restart.bat file by double-clicking it.
Your PC will reboot again. Once you are back in Windows, test your internet again.

If it still does not work, attach the fixme_results.txt file the .bat file created.

 

Thank you Thisisu. The reg edit work. I have my connection back.

What was I infected with?

Again Thank you.
Rick

 

Most likely it was a Max++/Sirefef/ZeroAccess rootkit. It is able to remove entire services from the registry.

[[ Edit: Yes it was ZeroAccess ]]

Glad to hear you're back up and running
Are you having any other malware problems?

If you are not having any other malware problems, it is time to do our final steps:

1. We recommend you keep SUPERAntiSpyware and Malwarebytes Anti-Malware for scanning/removal of malware. Unless you purchase them, they provide no protection. They do not use any significant amount of resources ( except a little disk space ) until you run a scan.
2. If we had you use ComboFix, uninstall ComboFix (This uninstall will only work as written if you installed ComboFix on your Desktop like we requested.)
   • Click START then RUN and enter the below into the run box and then click OK. Note the quotes are required
   • "%userprofile%\Desktop\combofix" /uninstall
     • Notes: The space between the combofix" and the /uninstall, it must be there.
     • This will uninstall ComboFix and also reset hidden files and folders settings back to Windows defaults.
3. Go back to step 6 of the READ ME and renable your Disk Emulation software with Defogger if you had disabled it.
4. Any other miscellaneous tools we may have had you install or download can be uninstalled and deleted.
5. If we had you download any registry patches like fixme.reg or fixWLK.reg (or any others), you can delete these files now.
6. If running Vista, it is time to make sure you have reenabled UAC by double clicking on the C:\MGtools\enableUAC.reg file and allowing it to be added to the registry.
7. Go to add/remove programs and uninstall HijackThis if it present
8. Goto the C:\MGtools folder and find the MGclean.bat file. Double click on this file to run this cleanup program that will remove files and folders
   related to MGtools and some other items from our cleaning procedures.
9. If you are running Win 7, Vista, Windows XP or Windows ME, do the below:
   • Refer to the cleaning procedures pointed to by step 7 of the READ ME
     for your Window version and see the instructions to Disable System Restore which will flush your Restore Points.
   • Then reboot and Enable System Restore to create a new clean Restore Point.
10. After doing the above, you should work through the below link:
