Services manager



Choosing which services to display in the list:

You can choose to hide the system protected files, all Microsoft files, or all signed files from the list by clicking the List settings button.

It will open a dialog box similar to the one in the picture below:

List settings 

Select the radio button corresponding to the desired option.

If you select Show all services, then all the services will be shown.
However, you will not be able to delete or rename system protected files using UVK.

If you select Hide system protected files (Default), then only the non protected files will be displayed.
If you select Hide all Microsoft files, then no Microsoft files will be shown.
If you select Hide all digitally signed files, then UVK will verify the digital of all files and display only the unsigned ones. 

If you use the second or third option, and you suspect that the system or Microsoft files have been infected or replaced, check the aditional option Verify the file signatures. This will ensure only genuine files are hidden from the list.

Deleting a service and optionally the associated file:

To delete a service or driver without deleting the destination file click Delete service menu or just press Del. You can also click Delete service but make sure that Also delete file is unchecked or the service file will be deleted!

To delete  a service or driver and the corresponding file click Delete service menu or press Ctrl+Del. Alternately, you can check Also delete file and click Delete service.

Deleted files are moved to the recycle bin, so if you make a mistake, you can always restore them from there.

Before deleting a file, UVK always checks its signature, and if you're about to delete a file digitally signed by Microsoft, a message box will popup as shown in the image below.

This security feature is intended to prevent deleting system files by mistake, so when you got this message, you should click No, unless you know exactly what you're doing.

Microsoft signed

This software was created to delete virus, not system files, so, in a case like this one, if you click Yes, you're at your own risk. We won't be responsible for what may happen to your computer.

System services:

Be very careful when deleting services, specially system services. Don't delete services whose files are signed by Microsoft, unless its a service belonging to a software already uninstalled and the service has been left behind, or other similar cases.

Often, Trojans and other types of malware infect these services, that's why it's very important to verify their files signatures.

Below is a list of services whose files must be digitally signed by Microsoft. If they're not, your system is probably infected. This list contains only the services that are usually always running.
