I have uins000.exe in my Uniblue/Speed Up My Pc, that I downloaded as a trial offer. I then downloaded a free registry cleaner. Now I get unins000 error messages and cannot uninstall Speed Up My PC. From researching I have found this file is used by more than 1 software. All I want is a copy of it to put in the correct folder. I do not know if it is a generic exe or if it is tied to a certain folder. I just cant seem to find the answers.

If you delete a unins000.exe or unins000.dat file you maybe can't uninstall a program.
essential file to uninstall software installed with inno setup. This file should be in the program install dir. If you find it in other locations investigate it.

My anti-virus program, iolo System Shield, just found C:\PROGRAM FILES\MALWAREBYTES ANTI-MALWARE\UNINS000.EXE to be infected with "W32/InstallCore.L", which it labelled as "Malicious Software."
I just loded up my computer and my security said that unins.exe was a virus and it was slowing down my pc, stealing my passwords, and was filming me.
Its essential for removing a program that you installed that you don't want anymore.

It shows up as an uninstall file for a Gimp plugin I run. Appears to be no threat.
