"spi is trying to modify the system network configuration".

I was experiencing this issue too, and I believe spi is a residue of Mackeeper app that I uninstalled. This Mackeeper has suddenly coming from no where might be from app that my girlfriend installs. What I did to resolve this is just by uninstalling the spi from application list in the finder. Hope this would helps. And the prompt is gone, so do the pop-ups in the browser whenever I open up a new tab.

Hi Mark

How would one access the library? I initisally deleted it and MacKeeper but everytime I restart my comp... this pops up. Hope you could help me out here.

Also... what can I run to delete all these malware?

I just recently had this notice start coming up as well. It started after I installed Toast Titanium, and is also affiliated with being an artifact of other software installations. I only allow software that I am sure I installed to make changes, and simply deleted the app which fixed the problem

I wouldn't allow that to run either, since most Mac software does not use an uninstaller. Is the 'uninstaller' in your apps directory? Do you know what software package initiated this? Try looking for uninstaller by going to preferences->Users&Groups->Login Items and revoke its permission to run, although It would be better to find the source of the problem and just get rid of the package itself.

I found the culprit and did delete it, then "uninstaller" was trying to launch. Found THAT in the Library, stopped it from loading inUSERS AND GROUPS, deleted it and on reboot, all's fine. BUT it also gave me the chance to examine the storage and I deleted 8 gigs of junk files! All's good!

Thanks for the help!

1: Find SPI and dump it. After I did, "uninstaller" started up. Found it in the Library/SPI/blahblahblah
Dumped THOSE two files, reboot, clean.

I did all this at work; lady at the front desk made a crack about why nobody else (old PCs) had a problem; I replied that it must've been them Russian **** sites yesterday.

I was thinking that SPI stands for "Serial Peripheral Interface". It's a fairly slow speed interface that's used for all sorts of things, although I'm not sure what on a Mac. Memory modules use something similar called the I2C interface.

You can take a look in System Report, and it will have it under Hardware>SPI. The message I get when I click on it is "This computer doesn't contain any SPI devices."

Hey! I'm getting this same message (crash report of uninstaller / illegal operation) now that I've deleted SPI. Wondering if you were able to find a fix? I'm updating to High Sierra right now. Hoping that'll resolve it. Figure I'd check in with you just in case! 🙂

I tryed to resolve it and i couldnt find the spi or any relation on library folder.

The only way how my computer was new that i figure it out was create a new user with out any record from a uninstaller to boot.

Happened to me when opening a downloaded torrent app (that's the chance you take with these). Cancel out of the window with the spi message and cancel any subsequent messages regarding uninstaller.

Locate spi.app in your application folder and move it to the trash. Locate the spi folder in your library folder and move it to the trash also. If you don't have access to your library folder:

Empty trash and restart. This worked for me.

I have the same problem. But i got spi while trying to download a software and thought it was the actual software i was trying to download, so unfortunately i've allowed it to modify the configuration 😟

Deleted spi, now i've located uninstaller and moved it to the trash.

Do i still need to reset my macbook to factory settings to get rid of it?

You can try to search for "uninstaller" and delete it, but i only got rid of it by resetting my macbook to factory settings, it's been a week now and i havent got any problems after that, so i really think that's gone for good!

yes, you do. it will be like a brand new blank mac, there will be only the applications that come originally with it. so you have to backup before resetting it to factory settings if you don't wanna loose your stuff but beware not to backup the malware too haha

This look familiar?

I deleted it and now get a message about uninstaller trying to launch.
