The 1st stage of a MBAM scan is to check for updates, but as I was offline this could not occur. I was offline and it takes 2 or 3 minutes for my modem and router to complete start-up, so I decided to run the custom scan offline. This would only take a minute or so to complete. I wanted to run a quick custom scan of a USB memory stick rarely connected to my PC. Garbo writes: This thread may have gone cold, but a small anomaly I spotted yesterday: Looking at the “threat scan” report, it checked 231,199 files in 2m 21s (on a Dell Optiplex 790 with SSD C: system partition and separate HDD D: data partition running 64 bit W8.1 Pro). no noticeable slowing down or excess RAM usage affecting my normal PC usage. I have had both scheduled “threat scan” and “hyper scan” occur in the background and not been aware of these i.e. It has been a couple of days now since I updated and so far I have not been aware of any differences between versions 3 and 4. You may need this for a later MBAM update so it is probably best to leave the rule in place.) (The mbsetup.exe is a temporary file and no longer present, so be careful if you delete firewall rules for executables no longer present. I did not note the protocol (TCP, UDP …?) or ports used. if you normally block unknown outgoing accesses and do not get a notification when an unknown executable is blocked. If you want to create outgoing rules for these before updating and possibly save yourself some problems e.g. Garbo writes: Further to my comments above, the 2 extra MBAM files needing outgoing internet access for an in-place update from MBAM version 3 to version 4.0.4 are:Ĭ:\programdata\malwarebytes\mbamservice\instlrupdate\mbsetup.exeĬ:\program files\malwarebytes\anti-malware\mbaminstallerservice.exe PS: I use MBAM Premium (I have a lifetime licence bought when these were available a few years ago) alongside Panda AV. The problems with the MBAM service not starting on PC startup which plagued early iterations of MBAM version 3, do not appear to be there with version 4.0.4 (based on maybe 6 or 7 starts across 2 PCs so far). The UI has been moved around a bit and to my eyes looks less professional as a result, but most of the settings are still there. My other, newer W8.1 PC updated its version of MBAM in place without any problems. So if you have problems after an in place MBAM 3 update try a clean install from scratch. A full scan now completed in about 15 minutes (from memory), so similar to previously. I uninstalled MBAM (using Revo uninstaller to remove some left behind files, but leaving in place the firewall rules), downloaded the MBAM version 4.0.4 installer (which is now a small online installer) and installed MBAM 4.0.4 again. I then found that a full scan which previously only took 15 minutes or so, even on this slow PC, was still running at about 100,000 files scanned 2 hours later, so I concluded that this update had not completed successfully! I was unable to create the new rules quickly enough! I temporily allowed all outgoing accesses and the installation “apparently” completed successfully. Initially the update process got itself into a tangle because it needs new outgoing internet accesses and by default I block unknown programs and get a notification using Windows Firewall Notifier (WFN) (similar to the better known Windows Firewall Control?). By chance I was successfully updating W7 on my old Acer 5611 laptop yesterday, and as I usually do when I take it out of its bag each month, I updated other programs which need regular updates including Malwarebytes Antimalware (MBAM) and I stumbled upon this new version 4.0.4.
