corrupt filesOn June 27th at 7:46 pm all my database files ( in the same folder)
became corrupt( Probably around 100 different files all with the same time stamp of June 27 7:46 pm) I think the file that did it was da8f5167.exe. I can see the data briefly in excel when the file starts to open. In Access 97, the message starts with unrecognized file and no data appears. I have tried a lot of stuff but none of it seems to work. Any help? On June 27th at 7:46 pm (my time), no significant event occurred in the world
that I'm aware of, which would affect Microsoft Access worldwide. (though I wouldn't discourage you from giving more details than necessary, usually it's the other way around) If all your database files in a folder became corrupt, then (since it's unlikely you were running all of them at the time) you "merely" had an "event" such as a catastrophic failure in your PC. As such, this is hardly to do with Microsoft Access, is it? Do you have backups (including off-site backups)? If not, you will have next time, is my humble opinion. (it's not really a reasonable question. I appreciate you are probably in a panic, and if so stop it) Chris Show quoteHide quote "sidfarkas" <valleym***@b2xonline.com> wrote in message news:1152656839.834755.115220@75g2000cwc.googlegroups.com... > On June 27th at 7:46 pm all my database files ( in the same folder) > became corrupt( Probably around 100 different files all with the same > time stamp of June 27 7:46 pm) I think the file that did it was > da8f5167.exe.

not recognize the file. There were approx. 100 files in this folder. Most of them were in subfolders. All the files now have the same date and time on them. Some were mdb and some were xls files. Even if I tried to open all the folders in a short period of time, they would not have the same time on them. Mdb and Xls files in other folders were not corrupted. This file, da8f5167.exe, was in my system 32 folder. It also had the same time on it. It will not open when I click on it. When I right click on it, the properties have no id as to what software company wrote it.I have googled the file and it is not recognized. I have run PC Tools Antivirus software on my computer a dozen times and it does not see it. I have tried to import the data into new mdb files and it will not work. If this is a new virus it is powerful.

Check how many bytes each MDB file has. It should be a multiple of 4096, because that's the size of a data page. If the file size is other than a multiple of 4096 bytes, then data was added or subtracted from the file, which shouldn't happen unless a virus is involved or someone is messing with the file, like opening it in Word and then saving it in Word. > Mdb and Xls files in other folders were not corrupted.

somehow and said it was blank with "{" repeated many times at the beginning of the file. My old data was one week old but better that no back up at all. I hope that the person who wrote this virus, his armpits are infested with the fleas of a thousand camels.
