HI , I'm using XP sp3 with all latest updates, I've added the exclusions to my Avast antivirus including ( data-cdn.mbamupdates.com) to webshield, and added it's IP to Beethink which it accepts in it's white list, however it still blocks the Ip'slisted above(mwbyte.vo.llnwd.net at 087.248.205.254 and 087.248.205.253), which seem to be, those that supply the updates as mentioned above when I unblock one of the above Ip's it seems to let mbam update, my worry is that these IP addresses are being blocked for a reason, avast 4.8 pro, for e.g. has no such problems updating, so why is mbam seeking these sites for update? Thanks for your comments guys, any ideas?
