your best bet is to let the virus load and then use the task manager to see what is running. Look for names and files for this virus and look for those folders.
Whne you have identified those folders and processes you can then use the process name to search the registry from regedit.
delete the lines that reference the virus.
It sounds simple and for the most part it is. It will take time to locate all of the files, folders and startup commands.
This is how I get rid of viruses.
Also, once it is cleaned, you should make a backup copy of your registry. THe next time you get a virus, you can stop the processes, delete the folders and import you copy of the registry.
If this is a variant of the "Internet Security" virus, it won't LET you run task manager. God, that was a beast to get off my daughter's machine. I had to finally flatline it and re-install windows.
