excuse me, my english is bad, but I hope you understand me.
In McAfee U3 (v1.0) can replace the scan-engine 4.3.20 with engine 4.4.00.
Step 1) for example; rename "AV_188.8.131.52.u3p" to "AV_184.108.40.206.zip" Step 2) unzip it Step 3) in the folder ...\Data\AV\ replace the SCAN.EXE (4320) with SCAN.EXE (4400) Step 4) in the same folder in the file "engine_md5sum.txt" use for SCAN.EXE "md5sum" 509043caf172e8fc09bc97459a5fff0d Step 5) make again a zip-file with the folders Data, device, host and Manifest (but true a zip not a renamed rar) Step 6) uninstall the old U3-McAfee (v1.0) Step 7) eject the U3 drive and reconnect it Step 8) install the changed version McAfee U3
Though the program-windows show 4320, the engine 4.4.00 works correct now.
many thanks, I've forget it. All replaced files are 26.10.2004 04:40 "engine_md5sum.txt" 5d2b5a3ea032cd55f751ccbb6e8a46eb *LICENSE.DAT e0824f9b077e6ceb5d10769f4f410118 *MCSCAN32.DLL c103a586c2db47925bdda381ac74203e *MESSAGES.DAT 509043caf172e8fc09bc97459a5fff0d *SCAN.EXE
5.1.00 will work now! Unfortunately, cause was my bad work.
I find out, all this files ("LICENSE.DAT", "MCSCAN32.DLL", "MESSAGES.DAT", "SCAN.EXE" and also "engine_md5sum.txt") must have exact the same date. (take SpeedCommander) The important date is 09.06.2006 05:00 (day.month.year).
