I can't believe I am thr first to find this but searches have found no other references to it. A dialogue box titled System Control Panel opens after boot and displays an error message reporting the following: Critical errors on hard drive Hard drive Clusters damaged Critical errors in RAM Critical errors in system RAM overheating (85 deg C) RAM resources reported as very low and denies access to the desktop until you run the diagnostic report tool which, in my case, cound 4 HDD errors, 4 RAM errors and 3 system errors. It then opens a dialogue report for each error - in my case 11 reports. All the various dialogue boxes can be closed - but they will reappear as soon as there is any attempt to open a program. The threatware alko does the following: Denies access to task manager and regedit. msconfig will run. Clears all items from the menu lists Clears all icons and images from the desktop Changes all file attributes to system and hidden, including the contents of the user's library folders (documents, pictures, etc etc) I found the offending program file - random character filename - in the program data file once I had identified it in msconfig as the latest addition. Once the msconfig reference was removed and the file deleted the system was clear on a reboot. I removed the reference in the registry as well once I had access to it. However, the program left permanent damage as follows: All icons and shortcuts removed All menu items removed Previous menu items (such as in the run command) no longer drop down Anyone else come across this one?
