Default hidden item description
A hidden item was found on your computer. Hidden processes, hidden files and hidden applications are displayed as suspicious items. The presence of these items can indicate the following:
- A normal, non-malicious application might be hidden for some reason
- Malware (a stealth virus, rootkit or spyware) might be hiding on the computer.
There are many examples of why items can be hidden on the computer:
- Apropos. This is a family of spyware that hides files and processes.
- XCP DRM Software. The copy-protection software included on some music CD's hides files and processes. While the files are not malicious, there are security risks involved with them.
- Haxdoor. Note that this backdoor hides important system files, which are not malicious themselves.
There are several actions you can do to hidden items:
Sending a sample to F-Secure (Advanced users)
- If you don't want to do anything about the hidden item, select "None" as the action
- If you don't want to be notified about the file in the future, select "Exclude" as the action
- If you are sure the item is not part of a normal program, you can rename it by selecting "Rename" as the action. This will prevent the hidden program from starting in the future. You should use the "Rename" action very carefully, because renaming important files may break the computer.
Since hidden items are often related to malware, we ask that you consider sending us a sample of the hidden files. Please follow the instructions on submitting samples.
Since the files are hidden, you might not be able to access them directly. To access the files, you might need to do one of the following:
- Start your computer in safe mode. Here are the instructions for starting Windows XP in safe mode. In safe mode, the files may become visible.
- Rename the files. After renaming the files and restarting the computer, the files may become visible. In some cases, the computer must be started in safe mode after renaming for it to be successful.
- Reboot your system using Windows Recovery Console. The files should be accessible when using the Recovery Console.
