What is "O2 bill Email Virus"?

Cyber criminals proliferate the "O2 bill Email Virus" scam by sending emails to many people. This method is known as a spam campaign. The main objective of this scam is to infect computers with the Emotet, high-risk malicious program, which can cause privacy issues and infect computers with additional programs of this type. Do not trust these emails or open attachments presented within them.

O2 bill Email Virus

This email is presented as a message from O2 (a telecommunications service provider) regarding a monthly bill. It contains a link ("Go to my bill >") that, once clicked, opens a PDF file, which is identical to the received email message - it contains identical text and a website link, however, in this instance, the presented link opens a Microsoft Word document. If opened with MS Office 2010 or later (with Protected View mode), the software should warn users that documents downloaded from the internet can contain viruses. By clicking "Enable editing" and then "Enable content" buttons people allow this malicious document to download and install the aforementioned Emotet computer infection. Cyber criminals use this program to steal sensitive, personal information such as logins and passwords, details relating to browsing activity, and so on. The gathered data might contain banking information that the program can use to cause financial loss. Furthermore, this program also operates as a Trojan - it proliferates other infections, thus causing chain infections. Therefore, ignore the "O2 bill Email Virus" scam and do not open the presented link. Note that cyber criminals often use names of various well-known companies.

"O2 bill Email Virus" is a spam campaign, a scam that is very similar to many others such as "TD Bank Email Virus", "Royal Bank Of Canada Email Virus", and "Unicredit Bank Email Virus". Typically, cyber criminals use them to trick people into installing high-risk computer infections such as Adwind, Pony, FormBook, and so on. These programs are designed to steal personal data that can be used to generate revenue for the developers and cause financial loss for the victims.

How did "O2 bill Email Virus" infect my computer?

In this case, it is not enough simply to click the link presented in this email. A link in the opened PDF file must also be clicked. Then, permission to enable macros commands (enable editing of content) must also be granted. Once these steps are performed, a malicious document (MS Word) installs and downloads the Emotet computer infection. Generally, these emails can lead to computer infections only if the attachments presented in them are opened.

How to avoid installation of malware?

Do not download attachments or click links in emails received from unknown, suspicious addresses. These emails are often presented as official and legitimate - cyber criminals use names of popular brands/companies, however, in most cases they are irrelevant to the recipients. In these cases, they should be ignored. Download software using official sources and avoid torrent clients, eMule, unofficial sites, third party downloaders, etc. Software cracking tools should not be used, since they often install malicious programs rather than activating any software. Furthermore, using these tools is a cyber crime. Finally, having reputable anti-virus or anti-spyware software installed and enabled can be a very good prevention. If you have already opened "O2 bill Email Virus" attachment, we recommend running a scan with Malwarebytes for Windows to automatically eliminate infiltrated malware.

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.

searching for malware file on your computer

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.
