The following instructions pertain to all current and recent Symantec antivirus products, including the Symantec AntiVirus and Norton AntiVirus product lines.


Disable System Restore (Windows Me/XP).
Update the virus definitions.
Restart the computer in Safe mode (Windows 95/98/Me/2000/XP) or VGA mode (Windows NT).
Run a full system scan and delete all the files detected as Download.Trojan.
Clear Internet Explorer History and files, if needed.

For specific details on each of these steps, read the following instructions.

1. Disabling System Restore (Windows Me/XP)
If you are running Windows Me or Windows XP, we recommend that you temporarily turn off System Restore. Windows Me/XP uses this feature, which is enabled by default, to restore the files on your computer in case they become damaged. If a virus, worm, or Trojan infects a computer, System Restore may back up the virus, worm, or Trojan on the computer.

Windows prevents outside programs, including antivirus programs, from modifying System Restore. Therefore, antivirus programs or tools cannot remove threats in the System Restore folder. As a result, System Restore has the potential of restoring an infected file on your computer, even after you have cleaned the infected files from all the other locations.

Also, a virus scan may detect a threat in the System Restore folder even though you have removed the threat.

For instructions on how to turn off System Restore, read your Windows documentation, or one of the following articles:
"How to disable or enable Windows Me System Restore"
"How to turn off or turn on Windows XP System Restore"

For additional information, and an alternative to disabling Windows Me System Restore, see the Microsoft Knowledge Base article, "Antivirus Tools Cannot Clean Infected Files in the _Restore Folder," Article ID: Q263455.

2. Updating the virus definitions
Symantec Security Response fully tests all the virus definitions for quality assurance before they are posted to our servers. There are two ways to obtain the most recent virus definitions:
Running LiveUpdate, which is the easiest way to obtain virus definitions: These virus definitions are posted to the LiveUpdate servers once each week (usually on Wednesdays), unless there is a major virus outbreak. To determine whether definitions for this threat are available by LiveUpdate, refer to the Virus Definitions (LiveUpdate).
Downloading the definitions using the Intelligent Updater: The Intelligent Updater virus definitions are posted on U.S. business days (Monday through Friday). You should download the definitions from the Symantec Security Response Web site and manually install them. To determine whether definitions for this threat are available by the Intelligent Updater, refer to the Virus Definitions (Intelligent Updater).

The Intelligent Updater virus definitions are available: Read "How to update virus definition files using the Intelligent Updater" for detailed instructions.

3. Restarting the computer in Safe mode or VGA mode
For Windows 95, 98, Me, 2000, or XP users, restart the computer in Safe mode. For instructions, refer to the document, "How to start the computer in Safe Mode."
For Windows NT 4 users, restart the computer in VGA mode.


4. Scanning for and deleting the infected files
Start your Symantec antivirus program and make sure that it is configured to scan all the files.
For Norton AntiVirus consumer products: Read the document, "How to configure Norton AntiVirus to scan all files."
For Symantec AntiVirus Enterprise products: Read the document, "How to verify that a Symantec Corporate antivirus product is set to scan all files."
Run a full system scan.
If any files are detected as infected with Download.Trojan, click Delete. If your Symantec antivirus program detects any infected files that it cannot delete, record the location of the file and the file name. Then do one of the following:
If the file is in a location other than the Temporary Internet Files folder, restart the computer in Safe mode a second time. Then use Windows Explorer, browse to and delete that particular file. Once this is done, restart the computer in Normal mode. For instructions, read the section on returning to Normal mode in the document, "How to start the computer in Safe Mode."
If the file is in the Temporary Internet Files folder, write down the entire path and file name. Then go on to section 5.

5. Clearing the Temporary Internet Files folder
Restart the computer in Normal mode. For instructions, read the section on returning to Normal mode in the document "How to start the computer in Safe Mode."

Log onto the computer using the name that was shown in the path that you wrote down in step 4c.

For example, if the path was:

C:\Documents and Settings\Linda\Local Settings\Temporary Internet Files\qrwmqczd.dll

log on to the computer as Linda.


Start Internet Explorer.
Click the Tools menu > Internet Options.
In the Temporary Internet Files section, click the Delete Files button.
Check "Delete all offline content," and then click OK.

Hai disabilitato il System Restore (se c'è)?

Prova a fare le operazioni che ti ho detto dalla "modalità provvisoria" di Windows.
