Also Known As: possible malware infections
Damage level: Medium

What is the "FileShare" email?

"FileShare email scam" refers to a spam campaign. These letters claim that several files have been shared with the recipients. It must be emphasized that the "FileShare" emails are fake, and none of their claims are true. Therefore, by trusting these messages, users can experience various severe issues.

"FileShare" email scam overview

The scam emails state that two documents - "Company Agreement.pdf" and "List of orders.pdf" have been shared with the recipients. They are urged to view the files by clicking the "Dσcuments" button.

Typically, emails like "FileShare" operate as phishing scams. They attempt to extract users' personal information, e.g., names, addresses, emails, telephone numbers, account credentials (i.e., usernames/passwords), and finance-related data (e.g., banking account details, credit card numbers, etc.). The data is obtained via phishing websites or files, which record the information typed into them.

The goal of all scams is to generate revenue for the criminals behind them. To elaborate, communication platforms (e.g., emails, social networking, etc.) can be used to ask contacts for loans or to proliferate malware (by sharing malicious files/links) - under the guise of the accounts' genuine owners. Finance-related accounts (e.g., online banking, money transferring, shopping, etc.) can be used to make fraudulent transactions and online purchases.

To summarize, trusting scam emails like "FileShare" - can lead to system infections, severe privacy issues, financial losses, and even identity theft.

Spam campaigns in general

"Norton Subscription Will Renew Today", ".xlsx Document For Your Preview", "Download The Pending Mails Manually", "Sharpsmart Inc. Email Scam", "Im In Possession Of All Of Your Private Data", and "HP ePrint Email Scam" are some examples of spam emails.

In addition to phishing and other scams, deceptive letters also spread malware (e.g., ransomware, trojans, cryptocurrency miners, etc.). Spam mail is quite prevalent - therefore, it is highly recommended to exercise caution with incoming emails and messages.

How do spam campaigns infect computers?

Spam emails cause infections via malicious files attached to and/or linked inside them. These files can be Microsoft Office and PDF documents, archives, executables, JavaScript, etc. When the files are opened - malware download/installation is triggered.

For example, Microsoft Office documents infect systems by executing malicious macro commands. This process is automatic in Microsoft Office versions released before 2010. Newer versions have "Protected View" mode that prevents it; instead, users can manually enable macros (i.e., editing/content).

It is noteworthy that virulent documents often contain deceptive messages intended to trick users into allowing macro commands.

How to avoid installation of malware?

It is advised against opening suspicious and irrelevant emails. The attachments and links present in these letters - must not be opened, as they can cause system infections. It is recommended to use Microsoft Office versions released after 2010.

Aside from spam mail, malware is also proliferated via dubious download channels (e.g., unofficial and freeware websites, Peer-to-Peer sharing networks, etc.), illegal activation tools ("cracks"), and fake updates. Therefore, it is crucial to download from official/verified sources and activate/update programs with tools provided by genuine developers.

It is paramount to have a dependable anti-virus installed and kept updated. This software has to be used to run regular system scans and to remove threats and issues. If you've already opened malicious attachments, we recommend running a scan with Combo Cleaner Antivirus 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".

Delete malware in Autoruns

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.

Search for malware and delete 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.
