I haven't been able to fix this, and I haven't found any malware. Very frustrating.

Do you have a different computer that you can download .zip files to? If so, download a small one there, onto a Flash Drive. Test the unzip there first...

2nd: Insert the Flash Drive with the zipped file into the computer you're having a problem with and try to view the compressed files on that computer.

Let us know what happens....

------------------------------------------------------------------
ETA: There are a lot of compression/decompression programs out there. You will find them on www.download.com. I prefer Infozip for a pinch, although it is a command line tool (only, AFAIK).

Infozip syntax example to test a .zip file for integrity: unzip -vt thecompressedfile.zip
Where: -v - verbose
t - test the file. Will not unzip it.

I usually use WinRAR which can open most archives. If there is a problem with this achive, I'll know if it is valid or not. I use Dropbox the same way and I've never had any problems with it, but I never use the the internal Windows ZIP opener. It may be you have it disabled in your copy of Windows.

You have a BAD Archive. All this means is that it was probably an incomplete download from Dropbox, or, an incomplete upload:

Yes.. the regular Windows unzip facility does not provide much info when things go wrong. That's why Infozip is mentioned.

All the best.

Well, the issue was not , he could not open "any" zip files, he just could not open that one, because it was a bad file. As a matter of fact, I have had this same problem with the Dropbox archiving thing, so I stopped using it. It probably stops uploading to the archive when the iPhone goes into sleep mode, thus making the backup archive incomplete. For it to work right, you have to keep the phone on and powered up to full power, which it does not want to do. Some iPhone Apps force the device to stay live, say Video apps , dropbox is not one of them, to it always renders incomplete archives when using that feature.

It is better to use the archiving feature with the website. Actually I don't know if he made this archive using an iPhone or the Dropbox website from a PC, but he should check the source and make sure it is complete there.

I had the same problem with Dropbox. What I found is that Dropbox can create valid ZIP files if you are logged into your own account, but if you are on a Link Share page, Dropbox cannot create valid ZIP files. The programming is wrong.

To get around this, I create a folder with some JPG files in it, and then create a ZIP file containing those files and place that ZIP file in the same folder.

When someone who has the link goes to look at it, the usual view of all the images is there. But down at the bottom is a line showing the ZIP file. If you click on the ZIP file name, a new page opens giving you the opportunity to download the ZIP file. And if you download it, you can open it just fine and see all the images.

Here's a link to a shared Dropbox folder demonstrating my workaround.

https://www.dropbox.com/sh/vknzuzbfzxskcem/rwEmziVAFh

First get Dropbox to download all the files and try opening the ZIP file it produces. Then just click on the ZIP file at the bottom and download it. You'll see the difference.

Your link is bad. Says dropbox, but the link is actually:

check dropbox folder name

I had a weird dropbox folder name somthing like "* JPEGS for EMAIL" which caused my windows 7 unzip tool to fail. I fixed the problem by renaming my dropbox folder to something like "JPEGS-for-email" and windows 7 unzipped the folder just fine.

Another way to open ISO files
If you occasionally have to open ISO files, but don't want to download a third party problem (certainly not one called demon or devil or whatever), here's one way to do it: in XP Mode, one of the options is to mount an ISO image rather than the CD-ROM drive at startup.
