The program doesn’t require installation and can also be run directly from a USB stick. Just run the program, set the Filtering slider to Risk level (level 7 to 9) and if you find any files marked in red, you need to check it before removing it.
Sysinspector can not delete a suspected file, so make a note of the displayed items and remove it manually. Before removing any suspected files, it is wise to check the file really a malicious one. You can use RunScanner for this.
