7z1900-x64 Virus
Leda Billock
While 7-Zip may sound like a good name for a PC virus, it's actually a legitimate utility that compresses and decompresses files. It also comes with a built-in file manager that helps you manage those files. If you share a computer, such as for business purposes, someone else may have installed 7-Zip without telling you. An IT person may also have installed the program on your computer. While it doesn't hurt to leave the app on your computer, you can delete 7-Zip quickly if you think you don't need it.
The 7-Zip utility won't harm your computer or steal information. To protect your computer from real viruses, install an anti-virus program and keep it running at all times. Real viruses may arrive in email messages, hide in files you download and infect your computer when you visit dangerous websites. Microsoft Windows comes with Windows Defender, a free malware protection program that guards your PC against malicious software attacks, but it's not an anti-virus program.
One reason to use 7-Zip is because it's a free open-source program that runs on any computer. You don't have to register 7-Zip to use it and the app integrates with the Windows shell, thanks to its creator Igor Pavlov. That means when you right-click a zip file, you'll see a menu option that enables you to unzip the file using 7-Zip. You can also use 7-Zip to create compressed zip files that you can share with others or store on your hard drive when you wish to archive information.
The program uses a file format known as 7z that can compress files more efficiently than some other compression utilities. This can help you save on Internet transmission times when you upload and download these files, reduce your data charges and save you space on your hard drive and other storage devices.
One downside of 7-Zip is that not as many people have it installed as have software to support traditional zip files, which are automatically supported by most modern operating systems. If you send someone a 7Z file, you may have to explain what it is, how to open it and even verify that it's not a virus or something else nefarious.
If you'd like to remove 7-Zip, press your "Windows" key to open the Start screen. You can then right-click the 7-Zip icon and then click "Uninstall" to view the Programs and Features window. This window displays your installed programs and highlights 7-Zip, the app you right-clicked. When you click the window's "Uninstall/Change" button, Windows removes 7-Zip from your computer. Before clicking that button, ensure that 7-Zip is highlighted; you don't want to uninstall the wrong application. You don't have to reboot your computer after removing 7-Zip.

Today, for the first time, MB 4.2.1.89 identified my 7-Zip executable and its install file, 7z1900 to be Trojan.SmokeLoader. They've been installed on the laptop for years. No word about it on here or anywhere else on the internet. Scanned as ok with Windows Defender. Quarantined them for the moment. BTW, noticed that MB has a 7Z.dll in its program directory.
Two other odd things: MB is "Unable to contact license server", and repeatedly fails to install a new update, even after I explicitly added the license for the affected laptop to my account by logging in on the same laptop (testmy.net shows download speed of 40 Mb and upload at 6 Mb).
I succeeded in getting the latest version (4.3.0) of MB to install on my 32-bit Windows 10 laptop by turning off Defender, but MB is still not showing under Virus & threat protection after rebooting, and I don't see any option to make MB the virus protector under Manage Providers in Windows Security. This information applies to a 32-bit Windows 10 system. My 64-bit systems don't have this problem; they show MB as the active virus protection. However, neither bit version can connect to the license server when I click on Account in the MB Settings.
Ultimately, the fix seemed to be to change the MB security setting to "Always register MB in the Windows Security Center." Of course, this allowed MB to appear in Windows Security settings as the Virus & Threat Protection, as you would expect, but it also allowed MB to connect to the license server (when selecting "Account" in MB settings), which I didn't expect. I think, if MB isn't registered with Windows Security Center, then Windows Defender interferes with MB attempts to install updates and contact the license sever.
Sorry to double up here. One more thing: I'm not sure how or why MB wasn't registering with Windows Security Center on this particular PC. I have 5 seats of MB and this was the only one that wasn't registering--maybe because it's the only 32-bit system? Maybe Windows 32-bit acts differently, or the MB 32-bit acts differently.
Like many issues, it happened after an update--either of Windows or of MB. Everything has worked fine for a year, with consistent Windows and MB updates being applied, and then, bang, an update happens and a problem appears. At least that's my surmise. Problem has been solved. Thanks for your help.
I've had this false positive too on the same day. I'd like to precise that in my case, the suspicious 7z.exe wasn't my main one, but one bundled to Sourcetree in its Program Files (x86) directory.
Is there any chance that it wasn't a false positive, but that the Trojan would have morphed and/or moved somewhere else in my system? I'm probably being paranoid, but reading a little on SmokeLoader, i thought it was the kind of tactic it would be able to do. Might have misunderstood what i've read.
My apologies for the inconvenience. Such issue often arise from an anti-virus that puts the GameAssembly file in quarantine since it recognized it as malicious. Rest assured that this file is completely safe (You can even verify yourself with ) In order to resolute this you would have to preferably deactivate your anti-virus, extract the game and add the files to the exclusions in your anti-virus program so that they don't get deleted. You should be able to re-activate your anti-virus without any issue afterwards considering that the game files have been whitelisted from the program.
Runtime errors are 7-Zip errors that occur during "runtime". Runtime is pretty self-explanatory; it means that these EXE errors are triggered when 7z1900-x64.exe is attempted to be loaded either when 7-Zip is starting up, or in some cases already running. Runtime errors are the most common form of EXE error you will encounter using 7-Zip.
In most cases, 7z1900-x64.exe runtime errors occurring while the program is running will result in the program terminating abnormally. Most of these 7z1900-x64.exe error messages mean that 7-Zip was either unable to locate this file on startup, or the file is corrupt, resulting in a prematurely-aborted startup process. Generally, 7-Zip will be unable to start without resolving these errors.
Finding the source of the 7z1900-x64.exe error is key to properly resolving these errors. Although most of these EXE errors affecting 7z1900-x64.exe will happen during startup, occasionally you will encounter a runtime error while using 7-Zip. This can occur due to poor programming on behalf of Igor Pavlov, conflicts with other software or 3rd-party plug-ins, or caused by damaged and outdated hardware. Also, these types of 7z1900-x64.exe errors can occur if it has been accidentally moved, deleted, or corrupted by a malware infection. Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.
If you're encountering one of the error messages above, follow these troubleshooting steps to resolve your 7z1900-x64.exe issue. These troubleshooting steps are listed in the recommended order of execution.
When the first two steps haven't solved your issue, it might be a good idea to run Windows Update. Many 7z1900-x64.exe error messages that are encountered can be contributed to an outdated Windows Operating System. To run Windows Update, please follow these easy steps:
If none of the previous three troubleshooting steps have resolved your issue, you can try a more aggressive approach (Note: Not recommended for amateur PC users) by downloading and replacing your appropriate 7z1900-x64.exe file version. We maintain a comprehensive database of 100% malware-free 7z1900-x64.exe files for every applicable version of 7-Zip. Please follow the steps below to download and properly replace you file:
GEEK TIP : We must emphasize that reinstalling Windows will be a very time-consuming and advanced task to resolve 7z1900-x64.exe problems. To avoid data loss, you must be sure that you have backed-up all of your important documents, pictures, software installers, and other personal data before beginning the process. If you are not currently backing up your data, you need to do so immediately.
CAUTION : We strongly advise against downloading and copying 7z1900-x64.exe to your appropriate Windows system directory. Igor Pavlov typically does not release 7-Zip EXE files for download because they are bundled together inside of a software installer. The installer's task is to ensure that all correct verifications have been made before installing and placing 7z1900-x64.exe and all other EXE files for 7-Zip. An incorrectly installed EXE file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
