I've tried MBAR on 3 computers in the last week or so and i'm 1.5 for 3 on getting to run. The problem i'm having is this error message: Administrative account is required to run this program. Please switch to another user account with administrative privileges and restart the program. On all 3 computers the user accounts were definitely administrator accounts. On the first computer, i couldn't get around this issue period, i had to aswMBR to find and remove the rootkits. On the second computer it ran like a champ, detected multiple infections and removed them like it knew it was doing. On the 3rd computer, which is my computer, at first i was getting this same error messages. I have 2 accounts on this machine, my primary user account and a second that never gets used, at all. Anyway, I checked the account settings for both users, checked their group memberships and all that good stuff, nothing, i restarted the computer, nothing. I removed both user accounts for every group except the administrators group, still nothing. So i decided to scan it MBAM, well, because i running out of useful ideas. MBAM found a single infected object in the recyclebin, but its path was masked from the OS, so at first it seemed like a false positive, or a ghost file, but it wasnt. I had MBAM remove the file, let it restart my computer and all was well. After it rebooted I started MBAR with no problems. I updated MBAR and started a scan, everything seemed to be going fine, except MBAR was taking a REALLY long time to scan my computer. 1:45 mins in to the scan i had to relocate, it was really late and i had to go home. I had told my laptop to hibernate, which it usually does without issues. Fast forward 18 hours to this afternoon. I grab my laptop and boot it and to my dismay i find out my laptop didn't hibernate for whatever reason, I looks like it hung up at some point during the hibernation process, because the battery was dead and windows was booting after having not been cleanly shutdown. so that whole scan was gone, however when i tried to run MBAR this afternoon, I am back to got this error again. I tried a few things, including running MBAM again, nothing. I would like to figure out what’s causing this, MBAR looks like it has promise of being a good utility and a nice addition to my arsenal, however i've got to get it to run consistantly first. Not to mention that i would like to scan my computer, i think its infected because its performance went completely south a couple days ago.
