This morning when I tried to install an update to Piriform Defraggler from FileHippo I got this error message
Two days ago, I was having trouble with my keyboard not functioning properly and after I got that sorted I did a full diskcheck; I noticed that in the summary it said that Windows had made alterations to the file system and compacted the security stream(at least that is a rough idea of what it said ! ).
My computer is working absolutely fine in all respects but I cannot install software updates. I have run a Malwarebytes quick scan and it found nothing untoward and I disabled and then re-enabled User Account Control. I am the administrator of this computer and there are no other users. I should be very grateful for any suggestions !!
