Installed or not Installed

Is it possible that this is a portable program. Those will run without installation.

Smooth things out by installing FileSeek free or FileSeek Pro [pay-for]. If the program works for you very well, the registry entries won't matter. :) I've FileSeek for some time now, I like the EZ usage. Concerning removing programs, I paid for Revo Uninstaller Pro [does 32 and 64 bit removals] -- and Revo really works, including removing all registry entries also.

It's not portable:

Click the 'Download Now' button to download FileSeek (recommended)
Download without Installer (1.84 M)
Download MSI Installer (2.02 M)

MSI = windows installer.

Without (MSI) just means that it installs anyway.

Okay forget the above - it is portable.

Ran the program and I get this:

Folder in AppData

Windows Tracing

Firewall Rules

Connects to check for updates and send usage statistics

Creates hidden .ini file

Creates a Shell Bag

Shell Bag

Revo Uninstaller won't help. You need to do a manual file/ folder / registry search.

To cleanup delete:

%Userprofile%\AppData\Local\FileSeek

Here's a list of registry entries found on my machine. Yours will be different particularly the firewall and shell bags entries but it might help you to know where to look.

I've never used AVG PC Tuneup. Most users here would not use those types of utility especially without a backup. If you want to find the registry entries try searching using RegSeeker:

HoverDesk - Download

Run the search and check the results carefully when the scan finishes. Use the backup option.

If you are sure that all entries related to the FileSeek program you can select them for deletion otherwise use [Ctrl+Enter] to highlight multiple entries one at a time.

When you are happy choose "Action" > "Delete Selected Entires"

Avoid the auto-clean feature.

I've used Auslogics and Wise registry cleaners for some time now. If you choose those two utilities, do only registry cleaning, avoid the other stuff, such other stuff can cause problems. Both of those can remove many embedded but un-needed registry entries. Resplendence's Registrar Registry Manager also is a powerful registry editor -- use very cautiously.
