I have been using MBAM for a number of years now and with V1 I rarely (if ever) had any problems. Since "upgrading" to V2 I've had no end of problems. My PC freezes, Malicious Website Detection keeps stopping and can't be started again, MBAM refuses to start at all; no icon in the tray and when you double click the desktop icon you get nothing but the UPC prompt asking if it's OK to start. I have just re-downloaded v1.75 as I refuse to have to go to these lengths for a so called "upgrade". I refuse to have to run diagnostic tools - this should be done in BETA testing, not after release! For further info though, you may want to know that: I am running a FRESH installation of Windows 8.1 Pro as I thought it may have been something in Windows that was causing the issues initially I have carried out the MBAM-Clean process on several occasions (prior to reinstalling and post installation of Windows 8/8.1) and the situation just repeats after a few hours, even if my PC is left on Neither of the services (using services.msc) will restart. I receive error 1067 for MBAMService and 1053 for MBAMScheduler the later of which is understandable as MBAMService isn't running. I would like to know if there is a later version of V1 MBAW than 1.75 because until such time these issues are addressed, I can't afford to spend the additional time required to keep V2 running; I'm not one of your BETA testers you know, they get paid! Your somewhat disgruntled user!
