It is not a virus.  That error just says the file is not commonly downloaded.  Try clicking on the arrow and see if it gives you the option to download.

I have updated the wallet GUI to the latest daemon and simplewallet.  You can get the latest update here: http://sourceforge.net/projects/dashcoinwalletgui/files/dashcoinwalletgui-1.1.1-windows.zip/download

Is the wallet not sending at all?  Are there any errors showing up?

Delete blockscache.dat, p2pstate.bin and poolstate.bin and your wallet.bin. ( But do not delete the .keys file)

The next version of the GUI wallet is here

You can grab it from http://sourceforge.net/projects/dashcoinwalletgui/files/dashcoinwalletgui-1.1.0-windows.zip/download
It is still Windows only right now.

Changes made:

• Supports multiple wallets
• Cleaned up and optimized some of the code
• Shows progress while syncing blockchain
• More form validation
• A cancel button has been added to the send page
• Blank passwords are now supported
• Enter key opens wallet as well as button

To import an old wallet, copy the wallet's .bin.keys, .bin.address.txt, and optionally it's .bin file to the wallets folder in the GUI wallet.

Now that miners have moved from Minergate, the blockchain has begun fixing itself.  Expect transaction problems to be a thing of the past (as long as miners remain off Minergate).

Resetting your wallet by following the instructions on the faq (http://dashcoin.net/faq/) should fix the issue.  Look under "My transaction says sent, but it never showed up."

I will be releasing an update this Sunday.

Slb and AdamWhite have been looking into the issues with the transactions, so they can give a more official response, but here's what I know.

Everyone should read this, especially the miners.  This is extremely important.

Minergate is running an outdated version of the Dashcoin daemon, one that is blocking most transactions that are > 10,000 bytes (which is a lot of them).  On top this, Minergate controls 40% of the Dashcoin network hashrate.  I remind everyone that cryptonote coins are controlled by the community, the miners.  Right now, 40% of them are contributing to a pool which is not including a lot of transactions in the blocks they mine.  Minergate has been refusing to reply to any messages sent to them.  So, to solve this, we need the help of the miners.  To that 40%, please stop mining at Minergate and contributing to Dashcoin's transactions issues.  It would be greatly appreciated, by the entire Dashcoin community.

Other pools running the correct daemon are:

https://www2.coinmine.pl/dsh/
http://dsh.extremepool.org/

More info can be seen in slb's and AdamWhite's previous posts.

I may not be a Dashcoin dev, but I am a dev working with Dashcoin.  I hope this qualifies me to answer.   

Slb is working on the Minergate issue right now, and is looking into getting transactions sending properly again.  I am currently working on the GUI wallet, and have a web wallet planned for the future.

Thank you.  I will look into this, and will try to incorporate a fix in the next release.

Expect an update this weekend that allows the managing of multiple wallets.

To anyone who is having issues with the wallet GUI, please post the version of Windows you are running, if your computer is 32 or 64 bit, and what in the wallet is not working (will it not open, can it not open a wallet, etc)?  That will help me a lot in figuring out what the issue is.

What makes you think it's not?  A lot has been going on, just look through the thread.

First rename wallet.bin to wallet.old.bin, and then open the wallet "wallet.bin".  The wallet will say it cannot find "wallet.bin" (as it was renamed), and it will begin to resync the wallet.  When that is done, try to send the transaction again.

If the above does not work, then rename wallet.bin to wallet.old.bin, and then go to %appdata%/dashcoin, and delete blockscache.dat, p2pstate.bin, poolstate.bin.  Open the daemon, and wait for the blockchain to resync.  Then, open simplewallet, and open "wallet.bin".  It will say wallet.bin cannot be found (as it was renamed), and it will begin to resync the wallet.

Once you are done, and the wallet is working again, you can safely delete wallet.old.bin.

This shouldn't be an issue with the wallet, but rather with the network.  See slb's last post on the issue with large transactions for an explanation.  If however, when you say the wallet is not working, you mean the wallet is throwing errors, then please post whether you were using the wallet command line version or the GUI, and the exact error message it gave.

I released Subtoshi about a month and a half ago, so Dashcoin could be traded.  Dashcoin has since been listed on Poloniex, and the trade volume on Subtoshi has dropped.  As of now, Subtoshi is costing me more to run than it is bringing in.  I am glad that Subtoshi was able to get Dashcoin trading going, but now that trading has died down, and for the reasons I stated before, I have decided to close down Subtoshi.  Thank you to everyone who used Subtoshi. I hope it provided useful.

The plan for Subtoshi's closing is as follows
Deposits will be disabled on October 26th, a week from today.
Trading will be disabled on October 31st.
After that, the exchange will remain open for withdrawals until December 31st.

I will have a more official announcement later on the website, and will be sending out an email regarding the closing of Subtoshi to everyone who has registered.

What version of Windows are you running?  Also, could you please post the exact error message?  Thanks!

I have added the link the Dashcoin Wallet GUI github project to my original post.  I have also added it in this post.

For those trying to run on Linux, I experienced some issues while running the wallet under Linux, which I am working out.

The Dashcoin Wallet GUI is here! Right now it is Windows only.  Mac and Linux builds will come later.  You can download it here:

https://sourceforge.net/projects/dashcoinwalletgui

This version contains the following features.  It will be updated as more features are added:

• Syncs blockchain with network
• Can load/generate a wallet
• Loads balance
• Loads address
• Lists transaction history (sends and receives)
• Can send Dashcoin

Github: https://github.com/pwstegman/DashcoinWalletGUI

To import an already existing wallet, copy wallet.bin, wallet.bin.address.txt, and wallet.bin.keys to the same directory as the wallet GUI.  Rename the files to wallet.bin, wallet.bin.address.txt, and wallet.bin.keys if they are not already named that.
