Finder.dat files in frequently used folders


I found several “Finder.dat” files on my XP Computer. They where to be found in frequently used folders but instantly disappeared, when I goggled for the files. As I have nerver ever been connected to a Mac and dont use Linux I don´t know, how these hidden files came to my computer. Could it be that a MAc user did spy on me and did leave his tracks on my PC? ???


I doubt that this is actually an infection, but we better be safe than sorry.

I´ll runn the scans,
but is it save to post ones logs to this relative large public?


AFAIK the logs are just informative and do not give any personal information (except the useraccount name you’re using)



I´m experiencing difficulties posting this message. first of all the HJT log.

The other engines did only find cookies. What wonders me, is that a2, having been run in third order, did find 50 additional cookies.
As you suggested not to delete anything with a2, I left them all. They´re in the same folders as the following two examples taken from the log:!A2
F:\Dokumente und Einstellungen\Y\Anwendungsdaten\Mozilla\Firefox\Profiles\lcefst0i.default\cookies.sqlite:1254815694375000 gefunden:!A2

most of the times, you don’t need cookies at all, so you can delete them using Ccleaner, or the Comodo system Cleaner.
I’ve looked at your hijackthis log and can’t see anything unusual. You’re computer should be safe.

I have no idea why all these finder.dat files are on your pc, but are you running any indexing software or so ? Perhaps they use it ?

best regards,


Hi experience,

thank you for answering.
I don´t think I use any sort of indexing software. What really made me nervous was that I just found these files ones and only in folders I had in frequent use. Once I searches on Google for “Finder.dat” they were gone and never appeared again. So I suspected someone spying at me and when he or she found out I had switched “show hidden files” and I googled for it, immediatly deleted everything.


I’ve also been searching on the net and can’t seem to find anything about it either. You should keep a close eye on it.

Are you running CIS ? If so, you can try blocking it to be certain ?


Hi, thank you eXPerience.

As far as I can see you can only block files when you know the folder, path etc… As the Finder.dat appeared (from my point of view) randomly, I don´t know how to block it for certain.

Best regards

A picture sometimes tells more than a thousands words. Don’t forget to push the + button to add to the list.

Can anybody confirm whether the wildcard I suggest is right?.

[attachment deleted by admin]

:slight_smile: Perfect! Thank you!

But I really doubt finder.dat was the cause. I´ll keep an eye on my connections and try to find out if there´s more behind it.

Anyway, thank you for your help :-TU

To ask you one more question, on the HJT log was nothing suspiciuos to be found?

couplate ( sorry for this expression)

while I´m surfing the comodo forum I notice someone has turned my CIS off !!!

Please don’t hijack somebody else’s topic. What do you mean with CIS turned off? Can you be more specific?
