Hello and welcome. Please follow these guidelines while we work on your PC:
  • Malware removal is a sometimes lengthy and tedious process. Please stick with the thread until Iíve given you the ďAll clear.Ē Absence of symptoms does not mean your machine is clean!
  • Please do not run any scans or install/uninstall any applications without being directed to do so.
  • Any underlined text in my posts indicates a clickable link.
  • If you have any questions at all, please stop and ask before proceeding.

DDS.pif
  • Disable any script blocking protection (How to Disable your Security Programs)
  • Double click DDS icon to run the tool (may take up to 3 minutes to run)
  • When done, DDS.txt will open.

  • In the right panel, you will see several boxes that have been checked. Uncheck the following ...
    • IAT/EAT
    • Drives/Partition other than Systemdrive (typically C:\)
    • Show All (don't miss this one)
  • Then click the Scan button & wait for it to finish.
  • Once done click on the [Save..] button, and in the File name area, type in "Gmer.txt" or it will save as a .log file which cannot be uploaded to your post.

Rootkit scans often produce false positives. Do NOT take any action on any "<--- ROOKIT" entries


If you have trouble running GEMR:

If this is a business PC you would likely be better served by your IT staff. There are a number of reasons I recommend this:
  • If your business has IT support, it would be wiser to utilize them as they are more familiar with your IT environment
  • Many companies have policies against employees doing this type of work on their PCs
  • Your business may have system policies or software versions in place that are business critical and should not be altered or removed. Obviously, I would have no way to know what they are. The tools we use for home/personal systems will occasionally alter system settings.
  • Posting your logs in an open forum like this could possibly expose proprietary business information.
Depending on your circumstances I'm willing to continue to try to help, but we may be severely limited by your restricted access to the system and software.

This is my old company computer that I purchased at a very reduced price. IT staff is no longer providing support.

Fair enough then. Please download those tool to your desktop then boot into the Safe Mode to run them. That should take Symantec out of play.

chicagocoupon :

Anything you post or attach is available to all of the registered users here. There is nothing I can do to change or alter that. If you still want to continue, please do this. If you would prefer to stop and seek help a different way, please let me know and I'll close the thread.

Posted Image Download ComboFix from one of the following locations:
Link 1
Link 2

VERY IMPORTANT !!! Save ComboFix.exe to your Desktop

* IMPORTANT - Disable your AntiVirus and AntiSpyware applications, usually via a right click on the System Tray icon. They may otherwise interfere with our tools. If you have difficulty properly disabling your protective programs, refer to this link If you can't disable your AV, run ComboFix from the safe mode.
  • Double click on ComboFix.exe & follow the prompts.
As part of it's process, ComboFix will check to see if the Microsoft Windows Recovery Console is installed. With malware infections being as they are today, it's strongly recommended to have this pre-installed on your machine before doing any malware removal. It will allow you to boot up into a special recovery/repair mode that will allow us to more easily help you should your computer have a problem after an attempted removal of malware.

  • Follow the prompts to allow ComboFix to download and install the Microsoft Windows Recovery Console, and when prompted, agree to the End-User License Agreement to install the Microsoft Windows Recovery Console.
**Please note: If the Microsoft Windows Recovery Console is already installed, ComboFix will continue it's malware removal procedures.

  • Once the Microsoft Windows Recovery Console is installed using ComboFix, you should see the following message:

Posted Image

  • Click on Yes, to continue scanning for malware.
When finished, it shall produce a log for you. Please include the C:\ComboFix.txt in your next reply.
Notes:
1. Do not mouse-click Combofix's window while it is running. That may cause it to stall.
2. Do not "re-run" Combofix. If you have a problem, reply back for further instructions.


Please include the following in your next post:
  • ComboFix log
