Report What is this file? in Archived General Discussion Posted December 23, 2014 HI, bsb.mltr. FEA5110B-C37A-4008-861D-44C2C862EB79.data_2.zip is a file used to update Maxthon's QuickAccess to provide new features. It should be downloaded from http://quickacces-dl.maxthon.com/ not from that url. I am wondering if IDM is installed in your PC? IDM may monitor and stop all zip downloading from Maxthon, so Quickaccess of Maxthon cannot be updated. If that case, every one hour, Maxthon may try to download that zip file once. If you have no IDM, or that zip file is downloaded more than 1 time per hour, please reported again. Thanks PS: we will update Maxthon to solve the compatibility issue with IDM.
