+ 0 Votes Ironically.... NotSoChiGuy 7 years ago Not five minutes ago, one of the developers I work with asked me to look at her PC, and she had about 10 files/directories of similar nature to what you describe. However, each file was identical in size to the system page file. The time of the creation of the file corresponded to her installing Visual Studio SP1 (I think that is what she said...at any rate...something along that line). I had her remove the files, and reboot the system. The files weren't recreated (which is usually a telltale sign of some sort of infection/malware presence), and the system was running just fine. I THINK it had to do with the install of the SP (memory intensive install??). However, I am keeping an eye out on it, and have a port monitor keeping track of her PC on the network. If anyone else has any info, I'd be receptive and appreciative. Thanks! + 0 Votes Not a Virus fcleroux 7 years ago I know what it is. Disk Erasing and Shredding utilities like "StompSoft's Digital File Shredder Pro" will create these patters and use them to fill up the drive with files containing this data and will then delete these files once completed. They will write these data files at offsets so that different data is writen onto the drive. If there is a problem and the program locksup or crashes, the Folder with all the data files will not be errased. Thus you will find the directory, the files and usually a full hard drive. Run StompSoft's Digital File Shredder Pro and you will see this directory and files get created. + 0 Votes Secure deletion oliver.brettschneider 7 years ago My guess is that your data in the folder was overwritten with the alphabet 20 times in order to make sure that the data could not be undeleted. the proces might have been interupted and therefore you are now sitting with the folder names that look like a scramble of the alphabet. + 0 Votes One of Your developers???? Dukhalion 7 years ago What is he/she developing? Sounds like one of my first programming attempts when I accidentally wrote a loop that eventually filled my disk with one large file. So, check wheather someone has been doing some programming (or tried some weird macros) on the computer in question. And don't settle for "No, I didn't do anything, honest". The fact that several antivirus programs didn't find anything is a further hint of this. + 0 Votes I assume its a Virus fatsaiko 7 years ago Its a virus, its called brontox or something. Yeah, they detected it once, and there was another version and they cleared it as well. I am assuming as it once affected my college server and duplicates itself all throughtout the network. Making all possible hard drives full of it. Even with an antivirus! as the antivirus detects it, not being able to clean it, and transfers itself to Quarantine. (primarly norton's antivirus) So the way to clear it up is by using a compact remover. http://www.compactbyte.com/cav/index.en.php Its an external tool which detects the virus. And also cleans it up. And you can always deleted those files by yourself i guess. Its just a suggestion, if it doesnt get cleared up. It must be something else then. Its worth the try thou! cheers. bob. + 0 Votes I had something like this years ago. CVB_X2Z 7 years ago I had something like this years ago. I found a folder in my temp directory that had over 10,000 zero byte files. I could not delete the folder but found I could delete the files just not all at once. I deleted 250 of the at a time. Once all of them were deleted I right clicked on the folder and clicked PROPERTIES and unchecked all. Then I deleted the folder. Then I restarted in safe mode and ran anti-viral and anti spyware programs. It did find something but since it has been years ago I do not remember the name of what it found. If you find a name for this please post it so others can check for it. Some spam emails or scripts on a visited page may have been the culprit but cannot say for sure. Always keep a log of any new folders created. I was using Win98 SE back then. Good luck if you decide to attepmt to track it back to its origin. + 0 Votes I'm curious - did you examine the contents of the files? Zeppo9191 7 years ago I'd have used Notepad to check the contents of some of the smaller files. (Of course, it wouldn't have been able to handle the larger ones.) That might give you some indication of what they were and how they came to be. + 0 Votes More than likely a virus. thegreek 7 years ago this is a good example of why it's a good practice to image your hard drive regularly and back up important files. With an image of a hard drive you could be back to normal and up and running within an hour. + 0 Votes Could be... mackman2011 7 years ago You possibly have a "decompression bomb". Somewhere you may have downloaded and unleashed a compressed file which just keeps replicating a certain file or file type. I had one on my home PC which kept filling up my hard drive with gif files. It was easy to delete manually after locating it. Try the forum at avast.com for some information and links to downloads that are helpful. Avast anti-virus will pick-up decompression bombs by catching any compressed file which will grow larger then a predetermined size. (Some false positives are possible) The avast scan log will give you the file name and list it as a decompression bomb. Avast has found three or four more decompression bombs since and I let them die a peaceful death in the avast virus chest. Disk compression seems to hold it at bay and give you some working space until you can get rid of it. + 0 Votes TRYING TO FIND A VIRUS IN A COMPUTER IS LIKE-- BALTHOR 7 years ago Trying to find dinosaurs in Viet Nam or planet Dune awards to the Earth in Baghdad.They might be there and they might be big! + 0 Votes My 50 cents steveoh 7 years ago The files may be leftover from a HDD testing utility. The time and date of the files may prompt the user to recall what was happening then. Were they created in one session or slowly over a period? What was the content of the files? 0's, random or maybe something that the developer may recognise. AV fails so often these days because of the speed that new viruses propagate. I have reasonable success removing viruses by examining the registry RUN and RUNONCE entries, also viewing the windows and system32 folders sorted by date and locating anything that smells. I look for random file names, small .EXE's and check that properties of .EXE's contain manufacturer information. Most virus and malware have no such info. Anything I don't trust is moved to a folder created in the root so I can replace it if I'm wrong. Over the years I've become reasonable familiar with good V bad files. The time investment is now paying off with the speed I can run through a system. Rootkits now force me to use a bootable CD. The registry may not be available but if I move the virus files the reg entries can't start them on next boot anyway. This isn't a 100% technique (about 70% success) and it may be a little dangerous but, I've won many battles quickly and easily without trashing any machines. I've lost a heap as well but the 15 mins it takes me these days is worth a try.
