UkLog.dat.old ??

Question

A couple of weeks ago, I notice this .dat file on my C:\ drive.  Does anyone know what UkLog.dat.old belongs to and whether it can be deleted without causing my pc/a program problems?  I have Windows 10 v 1803.

Hi Denise. I'm Greg, an installation specialist and 9 year Windows MVP here to help you.

You can delete a .dat data log file, and it's especially safe to delete if it is labeled old since that means it's the previous version before the last one taken. You'd only need to refer to those logs if you have problems resulting from whatever program made the log.

Or you can leave it as it won't harm anything unless you need the space.

If ever in doubt that you're infected Run a full scan with the most powerful on-demand free scanner Malwarebytes:

https://www.malwarebytes.com/mwb-download/. In the Scan Settings first set it to include scanning for Rootkits.

Clean up anything found, restart PC and then run again until it comes up clean.

Check for any remainders in Settings > Apps > Apps & Features, and also in each of your browser's Extensions, Home Page settings, Search service or Add-On's as shown here: https://community.box.com/t5/How-to-Guides-for-...

Then check for damaged System Files: https://www.lifewire.com/how-to-use-sfc-scannow...

If it cannot repair them see Step 10 here to continue: http://answers.microsoft.com/en-us/windows/wiki...

If you want to keep Malwarebytes as an on-demand scanner then you can turn off its Real Time trial version in it's Settings > Account Details tab.

I hope this helps. Feel free to ask back any questions and let us know how it goes. I will keep working with you until it's resolved.

This could have been created by any application you recently installed. Its just a log file and is safe to delete.

Answer 3

Thanks for your replies, Andre and Greg.  I don't know which of my programs created the .dat file but it could be the Samsung USB Driver for Mobile Phones that I installed a couple of weeks ago.  I have MBAM installed and I just ran a complete scan and the rootkit scan about a week ago and it didn't find anything.  I also ran MS Malicious Software Removal Tool that day, too, and it found nothing, so I don't think I picked up anything.  I've only had this pc for about a month and I'm not having any problems with it.  I just didn't know where that .dat file came from.  I Googled it and there was no information about it.  I'll just go ahead an delete it since it's a .old file.
