The usual thing - want to try and sort it out.....
I ran Task Manager when the two installers started and right mouse clicked one of the tasks and selected 'go to process'. This then shows that the image that is running is something like 'Simon.tmp':
I then did a search for these and found entries in c:\users\"windows account"\AppData\LocalTemp and c:\windows\prefetch
I deleted these files but there was a netlogger.exe which could not be deleted.
I then did a safe boot and got rid of all the files I could.
However, when I booted again the two installers start again.
I've also found that there is a file called 'Simon' in the c:\users folder that also appears to be associated with this software.
I've now deleted the entire contents of the c:\windows\prefetch folder as it appears that Windows maintains this folder with the maximum number of 128 entries.
I must say that I'm less than impressed with some of the crap that is on my PC. The 'C' Folder - I dread to think what all the files with what appears to be serial numbers is.....
The C:\Windows folder
Edited: After that clear up I rebooted the machine and the software did not try and install itself. I'll update this thread at some later stage to confirm that this has been fixed or not.
