What is the "Roundcube" email scam?
"Roundcube" email (subject: "- NOTIFICATION - Storage Full") is deceptive letter. Supposedly from Roundcube - a legitimate email service provider, the letter claims that recipients' have reached their mail storage limit and if immediate actions are not taken - their account will be blocked. It must be emphasized that this scheme has no connection to the genuine Roundcube email client and is using the name with malicious intent. This is a phishing scam, designed to steal users' email account credentials (log-ins and passwords), for the purpose of gaining full control over said mail accounts.
This letter, as its subject - "- NOTIFICATION - Storage Full" implies - states that recipients have reached the limit of permissible data storage on their email accounts. Allegedly, according to the system administrator, users' maximum of 99 GB storage space has been used-up. Therefore, if they fail to upgrade their account, certain features (such as receiving and sending mail) will be disabled. To upgrade, the letter instructs recipients to click the link presented below to immediately upgrade and raise the storage limit. Once the link is clicked, it opens a fairly legitimate-looking log-in page. However, as mentioned in the introduction, the goal of this scam is to steal users' email accounts. Therefore, all information presented in this letter is false and any mail account credentials entered into this webpage will be delivered to the scammers. Yet users tricked by this scheme risk more than just losing their email account. Though a compromised mail, other associated accounts may be accessed/stolen; e.g. social networking and social media, e-commerce (online store) and others can be affected. Thereby allowing the individuals behind this scam to make various online purchases, assume the recipients' identities and ask their contacts for loans and so on. To summarize, this scheme can cause serious privacy issues, financial losses and even identity theft. If attempts to log-in through this phishing site have already been made, it is strongly advised to immediately change the credentials of the email and all connected accounts. Additionally, it is recommended to contact official support of all potentially compromised accounts.

Deceptive emails are sent by the thousand, during operations called "spam campaigns". "Last Warning: Upgrade your email to avoid Shutting Down", "You have 46 Hours in order to make the payment" and "Google winner" are a few examples of scam mail proliferated in this fashion. These letters are typically presented as "official", "priority", "important", "urgent" and similar. Such schemes commonly use the names/titles of genuine services, companies, organizations, etc. - to further the impression of legitimacy. The only purpose of this mail is to generate revenue for the cyber criminals behind it. Many tactics are employed to achieve this goal; for example, tricking recipients into providing log-in details of various accounts, revealing personal and sensitive information, making monetary transactions (e.g. fake fees, payments, fines, etc.) and so on.
How do spam campaigns infect computers?
Systems are infected via malicious files attached to or linked inside deceptive/scam emails. Infectious files come in a variety of formats, e.g. archive (RAR, ZIP) and executable (.exe, .run) files, Microsoft Office and PDF documents, JavaScript and others. An infection in triggered by executing, running or otherwise opening a virulent file. Once opened, the download/installation of trojans, ransomware or other malware begins. To elaborate on how Microsoft Office documents cause infections, they do so by executing malicious macro commands. In MS Office versions released prior to 2010 - this process begins automatically, when the document is opened. However, in newer Microsoft Office versions - users are asked to enable macro commands (i.e. editing). Therefore, infections are initiated only if the malicious macros are enabled.
How to avoid installation of malware?
To avoid infections caused by malicious content sent in spam campaigns, it is highly recommended not to open suspicious and/or irrelevant emails. Any attachments or links present in dubious mail - must not be opened, as doing so can lead to a high-risk infection. Additionally, it is advised to use Microsoft Office versions released after 2010. These versions have "Protected View" mode, which prevents infectious documents from beginning malware download/installation - the moment the file is opened. Other popular proliferation methods of malicious programs include: illegal activation ("cracking") tools, fake updaters and untrustworthy download sources (e.g. unofficial and free file-hosting websites, Peer-to-Peer sharing networks and other third party downloaders). To ensure system health and user safety, it is crucial to have a dependable anti-virus/anti-spyware suite installed and kept updated. Furthermore, this software should be used for regular system scans and removal of detected threats/issues. If you've already opened malicious attachments, we recommend running a scan with Spyhunter for Windows to automatically eliminate infiltrated malware.

Extract the downloaded archive and run the Autoruns.exe file.
In the Autoruns application, click "Options" at the top and uncheck "Hide Empty Locations" and "Hide Windows Entries" options. After this procedure, click the "Refresh" icon.
Check the list provided by the Autoruns application and locate the malware file that you want to eliminate.
You should write down its full path and name. Note that some malware hides process names under legitimate Windows process names. At this stage, it is very important to avoid removing system files. After you locate the suspicious program you wish to remove, right click your mouse over its name and choose "Delete".
After removing the malware through the Autoruns application (this ensures that the malware will not run automatically on the next system startup), you should search for the malware name on your computer. Be sure to enable hidden files and folders before proceeding. If you find the filename of the malware, be sure to remove it.
Reboot your computer in normal mode. Following these steps should remove any malware from your computer. Note that manual threat removal requires advanced computer skills. If you do not have these skills, leave malware removal to antivirus and anti-malware programs. These steps might not work with advanced malware infections. As always it is best to prevent infection than try to remove malware later. To keep your computer safe, install the latest operating system updates and use antivirus software.
To be sure your computer is free of malware infections, we recommend scanning it with Spyhunter for Windows.
