"System Administrator Quota Update" email scam removal guide
What is the "System Administrator Quota Update" scam email?
"System Administrator Quota Update" is the name of yet another phishing spam campaign. This term defines a mass-scale operation during which thousands of deceptive emails are sent. The letters distributed through this campaign - claim that recipients' email inboxes have reached their storage limit and will not be able to receive/send messages. The goal of this spam mail is to promote a phishing website that is disguised as an email account sign-in page. Sites of this type are designed to record information entered into them; in this case - account log-in credentials (i.e., email addresses and passwords). Hence, by trusting these scam emails, users can have their mail accounts stolen by scammers.
The "System Administrator Quota Update" scam emails (subject/title "SECURITY ALERT!!!!"; may vary) falsely state that recipients' mailboxes have reached 98% of their quota limit. This will supposedly prevent letters from being sent and received. These deceptive emails instruct recipients to update their accounts to 5 GB storage - to avoid losing letters and prevent the mail account from being deactivated. Once the button presented in the emails is clicked - it leads to the promoted phishing website. Trying to sign in through this page will expose the log-in credentials to the scammers, thereby allowing them to gain access and control over the corresponding email account.
Emails are of particular interest to scammers and cyber criminals because they are commonly connected to other platforms and services (e.g., they can be registered through the emails). Therefore, by obtaining emails - access/control may be gained over the accounts associated with them. To elaborate on how the hijacked accounts can be used, then communication platforms (e.g., emails, social networking/media, messengers, etc.) can be employed to proliferate malware by sharing malicious files or links. Alternatively, scammers can pretend to be the accounts' genuine owners and ask the contacts/friends/followers for loans. Finance-related accounts (e.g., banking, e-commerce, online money transferring, digital wallet, etc.) can be used to make fraudulent transactions and/or online purchases. To summarize, by trusting the "System Administrator Quota Update" scam letters - users can experience severe privacy issues, significant financial losses, identity theft, and other serious problems. If attempts to sign in through the phishing website have already been made - it is advised to immediately change the log-in credentials of potentially compromised accounts. Furthermore, it is recommended to contact the official support of the endangered platforms and services.

"Outgoing Mail Error", "Verify Your Email Account", "Secure your email", "Monthly Email Validation" are a couple examples of phishing spam campaigns targeting email accounts. Scam letters are typically disguised as "official", "urgent", "priority", "important", and similar. Aside from phishing and other scams, deceptive emails are also used to distribute malware (e.g., trojans, ransomware, cryptocurrency miners, etc.). Regardless of what scam emails promise, claim, request, or demand, their sole aim is to generate profit at user expense. Scammers and cyber criminals frequently use spam mail; therefore, it is strongly recommended to exercise caution with incoming emails.

How to avoid installation of malware?
To avoid infecting the system via spam mail, it is advised against opening suspicious and irrelevant emails - especially any attachments or links found in them. It is recommended to use Microsoft Office versions released after 2010. Malware is also spread through untrustworthy download channels (e.g., unofficial and free file-hosting websites, Peer-to-Peer sharing networks, etc.), illegal activation ("cracking") tools, and fake updates. Therefore, it is important to only use official and verified sources. Additionally, all programs must be activated and updated with tools/functions provided by legitimate developers. To protect device and user safety, it is crucial to have a dependable anti-virus/anti-spyware suite installed and kept up-to-date. This software has to be used to run regular system scans and remove detected/potential threats. If you've already opened malicious attachments, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate infiltrated malware.
