Symantec have posted details of a potential vulnerability whereby malware could be hidden from scanning. This effects Norton SystemWorks 2005 and 2006. Users are advised to update the software:
QuoteNorton SystemWorks contains a feature called the Norton Protected Recycle Bin, which resides within the Microsoft Windows Recycler directory. The Norton Protected Recycle Bin includes a directory called NProtect, which is hidden from Windows APIs. Files in the directory might not be scanned during scheduled or manual virus scans. This could potentially provide a location for an attacker to hide a malicious file on a computer....
Symantec product engineers have developed and released an update for products affected by this exposure. The update is available through Symantec LiveUpdate by running a manual update. To manually update via Symantec LiveUpdate, users should:
Open Norton SystemWorks
Click on LiveUpdate
Run LiveUpdate until all available Symantec product updates are downloaded and installed
This update will require a system reboot.
