Good day.:)
After I log-on to my user account this message pop-up "C:\windows\system32\lsass.exe cannot be located. Please specify a specific location at the Search button".
After I click the Ok button, the toolbar "Run" was deleted. However, if I log-in in a different user, the "Run" toolbar is present but I can't run the "msconfig"? What shall I do?

Windows errors related to isass.exe ?
Isass.exe is registered as the Optix.Pro virus which carries in it's payload, the ability to disable firewalls and local security protections, and a backdoor capability. Check that isass.exe is stable on your computer.

Recommendation for isass.exe:
DISABLE AND REMOVE isass.exe IMMEDIATELY. This process is most likely a virus or trojan. It is highly recommended to Run a Free Performance Scan to automatically optimize memory, CPU and Internet settings.

VERY IMPORTANT!
Determining whether isass.exe is a virus or a legitimate Windows process depends on the directory location it executes or runs from.

I have a suggestion on how to disable this virus:
1.)First, configure the folder options to view the hidden files to also see if the virus has a backup file.
2.)If you see a backup, uncheck 'hidden' in the Properties it if it is hidden so you can rename it(including the original virus file) and then restart your computer. It should be disabled by then.
3.)Now you can delete the virus normally.

She asked about "lsass.exe" not "isass.exe"

Lsass is a valid Windows service: lsass.exe Windows process - What is it? (http://www.neuber.com/taskmanager/process/lsass.exe.html)

I tried to search for Isass.exe but it shows the smaller isass.exe

Lsass.exe contains a Lower Case "L", not an upper case "i"

The one with the Lower Case "L" is a valid system process.

The one with any case "i" is a VIRUS
