Their have been some isolated reports of users who've been hit by the new Skulls trojan on their phones.
This trojan has been distributed on some Symbian shareware download sites as "Extended Theme Manager" by "Tee-222". If you see it, don't install it on your phone. It will make you're phone useless and it will prevent it from booting up. Recovery could get tricky, especially if you don't have a third-party file manager software already installed on your phone.
The most obvious symptom of the trojan is that the typical programs on the phone won't work any more, and that their icons get replaced with a a picture of a skull. See below:
Skulls is a malicious SIS file that will replace the system applications with non-functional versions, so that all but the phone functionality will be disabled.
The Skulls SIS file is named "Extended theme.SIS", it claims to be theme manager for Nokia 7610 smart phone, written by "Tee-222".
If Skulls is installed it will cause all application icons to be replaced with picture of skull and cross bones, and the icons don't refer to the actual applications any more so none of the Phone System applications will be able to start.
This basically means that if Skulls is installed only the calling from the phone and answering calls works. All functions which need some system application, such as SMS and MMS messaging, web browsing and camera no longer function.
If you have installed Skulls, the most important thing is not to reboot the phone and follow the disinfection instruction in this description.
Disinfection
If you have installed F-Secure Anti-Virus but have not yet received database update
1.Open Applications menu
2.Click F-Secure Anti-Virus
3.Select update Anti-Virus from options # 4. Scan your device to remove malicious AIF files
5. Go to application manager
6. Uninstall "Extended theme.sis"
If you have not rebooted the phone after installing "Extended theme.sis"
Currently the only known method of uninstall works if you have some third party file manager installed into your phone.
1. Go to c:Systemappsappinst and delete Appinst.aif and AppInst.app
2. Open the applications menu
3. Look for web browser, it's icon should still be normal
4. Open http://mobile.f-secure.com
5. Download F-Secure Mobile Anti-Virus for your device
6. Install F-Secure Mobile Anti-Virus
7. Scan your device to remove malicious AIF files
8. Go to application manager
9. Uninstall "Extended theme.sis"

F-Secure is reporting a new Skulls Virus variant Skulls.B. Skulls.B not only disables applications on the phone but carries with it Cabir.B, a variant of the mobile phone virus spread between Symbian Series 60 OS based phones over Bluetooth.The Skulls virus targets Nokia 7610 smart phones.
