Global Uninstall Applications

[Spicy Support]

Hi,

Does anyone know how we can remove Malwarebytes and Spybot on all the devices under a group?

Any ideas Pulseway or 3rd Party?

Thanks

Phil

Hi Phil,

Have you tried sending the uninstall command from the Pulseway app in the Computer Details -> Installed Applications.

There is no option to uninstall theses programs in the uninstall section in Pulseway

So we have 100 PCs (not on a domain), which we have to uninstall the programs and then install Pulseway.

Any ideas would be good

Or silent / batch file install of pulseway would be good...

Try this script to uninstall Malwarebytes:

Credits go to cvucic from Malwarebytes Forms (post). I've modified it to use the Malwarebytes uninstaller rather than WMI which didn't work when I tested.

Just tested it on 2 PCs and it works perfect, Thanks Paul!!!!!!!!

Wishlist Removal Scripts 

- SuperAntispyware
- Spybot
 -ESET

We could then make 1 script to remove them all.

This would then enable us to push out Kaspersky without issues...
