"Your account has encountered an error 505" email scam removal guide
What is "Your account has encountered an error 505"?
"Your account has encountered an error 505" refers to a spam campaign, distributing phishing emails. The term "spam campaign" is used to define a large-scale operation, during which thousands of deceptive/scam emails are sent. The letters distributed through this spam campaign claim that recipients' email accounts have been blocked and to unblock them, they must reverify their mail accounts. This spam campaign is designed to steal recipients' email account log-in credentials (i.e. passwords) by requesting users to verify their accounts via phishing website.
The "Your account has encountered an error 505" emails, with the subject/title "Mailbox Noticification", state that recipients' email accounts have been blocked, due to an error that is specified as "error 505". Since the accounts are supposedly blocked - incoming mail cannot reach them. To recover the accounts, recipients are informed that additional security is required. Hence, they are instructed to confirm the detected activity and remove the error by verifying their account again. Users are to do this by clicking the provided link. The link opens a phishing website, which is disguised as a generic log-in page. This webpage is designed to collect any of the entered data, in other words - the passwords of email accounts. Scammers are particularly interested in stealing mail accounts, as they are commonly connected to other accounts. Therefore, through a hijacked email - scammers may gain access to associated accounts. Via stolen social media, social networking, messaging and other communication accounts - scammers can ask the contacts/friends for loans and/or proliferate malware by sharing infectious files - under the guise of the real owner. Accounts that directly deal with and/or store financial information (e.g. banking accounts or credit card details) can be used to make fraudulent transactions and/or online purchases. It must be emphasized that all of the information provided by the "Your account has encountered an error 505" letters is false. By trusting these scam emails - users risk loosing their email accounts (as well as ones connected to them) and this may result in severe privacy issues, financial loss and even identity theft. If attempts to log-in through the phishing website have already been made, users must immediately change the credentials (i.e. passwords) of their emails and all the accounts connected to them. Additionally, it is recommended to contact the official support of all potentially affected accounts.

"Important: You have 19 Pending incoming email(s)", "ProtonMail Email Scam", "Roundcube Email Scam" and "Last Warning: Upgrade your email to avoid Shutting Down" are some examples of spam campaigns, similarly targeting email accounts. Spam mail can have a wide variety of purposes and disguises; however, the end-goal is always the same - to generate profit for the scammers / cyber criminals. Scam letters are typically presented as "official", "important", "urgent" or otherwise "priority" mail. These emails can be used for phishing and other scams, as well as malware proliferation (e.g. trojans, ransomware, etc.).
How do spam campaigns infect computers?
How to avoid installation of malware?
To avoid malware distributed through spam campaigns, it is strongly advised not to open suspicious and/or irrelevant emails, especially ones received from unknown/suspect senders (addresses). It is crucial not to open any attachments or links found in dubious mail - as that can result in a high-risk infection. However, malicious programs are also distributed via untrustworthy download channels (e.g. unofficial and free file-hosting websites, Peer-to-Peer sharing networks and other third party downloaders), illegal activation tools ("cracks") and fake updaters. Therefore, it is important to only download from official/trustworthy sources, as well as activate and update software with tools/functions provided by legitimate developers. To ensure device integrity and user safety, it is paramount to have a dependable anti-virus/anti-spyware suite installed. Furthermore, these products must be kept up-to-date, used to run regular system scans and to remove detected threats/issues. If you've already opened malicious attachments, we recommend running a scan with Malwarebytes 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 Malwarebytes for Windows.
