Hi juditelucas,
You have an autorun infection,
To bad you didn't have the flash drive inserted before combofix.
You may be able to run flashdrive disinfecter and you then should insert the flash when the program asks.
Download this program, Flash Drive Disinfector by sUBs from
http://www.techsupportforum.com/sectools/sUBs/Flash_Disinfector.exePlug in your usb hd
Double-click Flash_Disinfector.exe to run it and follow any prompts that may appear.
The utility may ask you to insert your flash drive and/or other removable drives including your mobile phone. Please do so and allow the utility to clean up those drives as well (D: and external Disk)
Wait until it has finished scanning and then exit the program.
Reboot your computer when done.
Then we have to perform an extra scan with DDS to be downloaded here:
http://www.techsupportforum.com/sectools/Deckard/dss.exeThe first thing I want you to do is download Deckard's System Scanner.
1. Close all applications and windows.
2. Double-click on dss.exe to run it, and follow the prompts.
3. When the scan is complete, a text file will open - Main.txt
4. Copy (Ctrl+A then Ctrl+C) and paste (Ctrl+V) the contents of Main.txt in your thread in the HijackThis Log Help Forum.
5. A folder, C:\Deckard, will also open. In it will be another text file, Extra.txt.
6. Attach Extra.txt to your post.
Note: some firewalls may warn that sigcheck.exe is trying to access the internet - please ensure that you allow sigcheck.exe permission to do so.
What Deckard's System Scanner will do:
* create a new System Restore point in Windows XP and Vista.
* clean your Temporary Files, Downloaded Program Files, and Internet Cache Files, and also empty the Recycle Bin on all drives.
* check some important areas of your system and produce a report for your analyst to review. Deckard's System Scanner automatically runs HijackThis for you, but it will also install and place a shortcut to HijackThis on your desktop if you do not already have HijackThis installed.
When you get the two notepad documents, attach them to your next reply Main.txt & Extra.txt,
After you have run both flashdrive disinfector and DSS, also attach a fresh HJT log.txt,
