usa.scr file purpose and description:
This is a known worm or virus, and the file location on your pc is shown below. When this is run, most likely from an email sent to you, it would have also made a copy of the file under other names (like sh.scr). Be sure to verify the disk location to make sure it is the virus. If you have this virus, then most likely it has already deleted alot of files on your computer as that is the first thing it does. This would have arrived as an email attachment with a description to fool you into running it. This is a virus that should be removed. (See the details below for the actual location of this file.)
Actual file or task name: (Note that you can view the entire list here)
This is a screensaver file.
Where is the file or folder located on my computer?
The location will be found on your system at C:\WINDOWS\SYSTEM\usa.scr (It may also be in your system32 folder).
Be aware that many tasks will be similiar names to existing tasks or processes.
You can always view the running tasks on your computer by pressing ctrl-alt-del to view the windows
"task manager", and then view the "processes" tab. This will show you all tasks running or currently active
on your PC. Although this shows you all running tasks, it does not show dll file thats are loaded, as they
get loaded as part of other processes. Many spyware writers attempt to hide their files
on your computer, for example, usa.scr may be intentionally misspelled to look like a similiar task, or spyware may be named very
similiar to a Windows system task. The reason they do this is so you cannot easily recognize the name in your tasklist
as I have mentioned above. Make sure always check the location of the file if you are concerned.
You can always find the location of usa.scr on your computer by using your Windows search options, but
I will also try to list the file location of every file described on this website, so you can verify the correct location. You can view the entire tasklist directory with the link below.
