Unwanted folders appearing on my root c drive

Ever since I have had my new HP laptop, every day one or two folders appear on the root c drive with a long jumbled name of letters and numbers. In any one such folder there is a large text file of apparently meaningless data. On the advice of knowledgeable friends I just get deleting them. My comp is running fine otherwise but I want to stop these folders appearing - am afraid its some kind of chronic virus. Any ideas anybody?

 

Hi and Welcome to TSG!

Can you give some of the names of these folders please?

Kind Regards
Anthony

 

Thanks.. my most recent random folder is called 0b2f20e095b1d0b447bda564 and the text file inside is called msxml4-KB927978-enu.

Thanks for your help!

If you are seeing a lot of similar folders in your root directory, my guess is because Windows Installer is not cleaning up after itself after installing updates.
