Note: I can help you remove malware manually. Please avoid installing/uninstalling or updating any programs and attempting any unsupervised fixes or scans. This can make helping you impossible. First Track this topic. Then follow: 1) Can you please post your AVZ log: Note: Run AVZ in windows normal mode and make sure you are connect to internet. If avz.exe doesn't start, then try to rename the file avz.exe to something else and try to run it again. Make sure you have your web browser open in background before following the steps below. i) To create the log file, download AVZ by clicking HERE. Please save this file to your desktop or "My Documents" folder. ii) Next, unpack the file to a new folder using the Compressed (zipped) folders wizard built into Windows XP/Vista, or a zip utility of your choice. iii) Once you have unpacked the contents of the zip archive, please launch the file AVZ.exe by double clicking on it or right clicking and selecting Open. Note: If you are running Windows vista launch AVZ.exe by right clicking and selecting Run as Administrator. You should now see the main window of the AVZ utility. --> Please navigate to File->Custom Scripts. Copy the script below by using the keyboard shortcut CTRL+C or the corresponding option via right click. begin ExecuteAVUpdate; end. Paste the script into the execution window by using CTRL+V keyboard shortcut, or the "paste" option via the right click menu. Click on Run to run the script. --> Choose from the menu "File" => "Standard scripts" and mark the "Healing/Quarantine and Advanced System Investigation" check box. Click on the "Execute selected scripts" button. Automatic scanning, healing and system check will be executed. A logfile (avz_sysinfo.htm) will be created and saved in the LOG folder in the AVZ directory as virusinfo_syscure.zip. Upload virusinfo_syscure.zip to rapidshare.com and paste the link here. *It is necessary now to reboot your machine, because AVZ might disturb some program operations (like antiviruses and firewall) during the system scan. All applications will work properly after the system restart. Image Tutorial 2) Download and Run DDS which will create a Pseudo HJT Report as part of its log: DDS Tool Download Link. When done, DDS will open two (2) logs 1. DDS.txt 2. Attach.txt Upload the logs to rapidshare.com and paste download link in your next reply. Note: Disable any script-blocking programs and then double-click on the DDS.scr icon to start the program. If you did not disable a script-blocker that may be part of your antimalware program, you may receive a warning from your antimalware product asking if you would like DDS.scr to run. Please allow it to do so. If I'm helping you and I don't reply within 24 hours send me a PM.
