What is the "Sincere apologies for this delay" email?
"Sincere apologies for this delay" is a spam campaign proliferating the TrickBot trojan. The term "spam campaign" defines a large-scale operation, during which thousands of deceptive emails are sent. The "Sincere apologies for this delay" messages concern an unspecified proposal to a likewise indeterminate process.
Recipients are asked to review the attached document and provide corrections to proceed, however, rather than containing such information, the attachment infects systems with TrickBot.
The "Sincere apologies for this delay" emails are named "skype/webex/zoom?" (the subject might vary) and offer apologies for the late response to a colleague's 'proposal' (however, the word "colleague" is misspelled as "college"). It is suggested that this delay might be due the colleague of the recipient being absent from the office.
The messages reassure that this is not a serious issue and state that hopefully the unspecified process can continue in a timely manner. Recipients are asked to address the attached document and indicate any necessary changes. If the attached Microsoft Excel file is opened and the macro commands enabled, download/installation of the TrickBot Trojan is initiated.
The primary function of this malicious program is to steal information. TrickBot mainly targets credentials (i.e. IDs, usernames and passwords) of email, social media, social networking, e-commerce, online money transfers, cryptocurrency wallet, banking, and various other accounts.
To summarize, trusting the "Sincere apologies for this delay" scam emails will result in system infection and can lead to financial loss, serious privacy issues and identity theft. If it is suspected or known that TrickBot Trojan (or other malware) has already infected the system, use an anti-virus software to remove it without delay.

"Salesforce Email Virus", "Universidade De Lisboa", and "Philippine Overseas Employment Administration" are some examples of other malware-proliferating spam campaigns. Scam mail is typically presented as "official", "urgent", "important" or similar.
Additionally, due to the subject of the "Sincere apologies for this delay" emails being "skype/webex/zoom?", it might be the case that these messages are related to "Cisco WebEx virus" or "Zoom virus".
Note that scammers/cyber criminals often attempt to trick people into downloading/installing malicious programs disguised as content related to WebEx, Zoom or other communication platforms. As well as malware distribution, spam campaigns are also used for phishing and other scams.
Regardless of what the deceptive messages claim, offer, request or demand, the purpose is the same: to generate revenue for the designers.
How did "Sincere apologies for this delay Email Virus" infect my computer?
For example, Microsoft Office files cause infections by executing malicious macro commands. In MS Office versions released prior to 2010, macros are executed when a document is opened, however, newer versions have "Protected View" mode, whereby users are prompted to enable macro commands (i.e. to enable editing/content).
Therefore, malware download/installation is started only if the macros are manually enabled.
How to avoid installation of malware
Suspicious or irrelevant emails must not be opened, especially those with any attachments or links found in them, as doing so can result in high-risk infection.
You are advised to use Microsoft Office versions released after 2010, however, malicious content is also proliferated via untrusted download channels (e.g. unofficial and free file-hosting sites, Peer-to-Peer sharing networks and other third party downloaders), illegal activation ("cracking") tools and fake updaters.
Therefore, use official, verified sources and update/activate programs with tools or functions provided by genuine developers. To protect device and user safety, it is crucial to have reputable anti-virus/anti-spyware installed. This software must be kept up to date, used to run regular system scans and to remove detected threats/issues.

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 Combo Cleaner Antivirus for Windows.
