Once FSS is on-screen, be sure the following items are check-marked: If your firewall then puts out a prompt, again, allow it to run. Right-Click on fss.exe and select Run As Administrator. This will not affect any real-time protection of the Malwarebytes for Windows 😃.ĭownload Farbar's Service Scanner utility This here is a Windows 7 SP1 with ( supposedly) Microsoft Security Essentials. Note:- I had MB4.2 earlier and was uninstalled by the third party support and hence i ended up in downloading MB4.5.14 premium trial version. Thanks.Īttached are the application errors and diagnostic logs of MB support tool/FRST. The question i have - is the problem really due to corrupted OS or potential malware (rootkits?) that prevents to install/run antivirus programs? But I managed to install MB and performed quick scan that detected PUP exe and quarantined them.Looking forward to your support to diagnose potential issue with my system and provide a resolution. But i cant go with the option as i dont want to lose existing personal data/settings on OEM pre-installed OS and moreover, i dont have OS DVD/disk available to perform repair/reinstall now. They diagnosed the logs and suggested preliminary troubleshooting steps - sfc, dism, chkdsk but none helped and they had pointed the issue to OS corruption and advised OS repair/reinstall or upgrade. The app kept crashing, took their online support, they tried to uninstall the existing antivirus programs and reinstall it, but the reinstallation failed with error '***.sys failed to copy to destination directory'.

To give brief background on what leads me to this situation, I had installed third party antivirus (licensed version) a month ago and it was working well until the issue started a week back. I see 'Malware protection' and 'Exploit Protection' are not turned on and while trying to turn on, it keeps spinning and the button is disabled after a while.

I was able to open the application and do quick scan, however it keeps popping up error message 'Realtime protection error occurred -one or more protection layers are not responding'.

I have installed MB-4.5.14 premium trial for windows.
