Avoid getting scammed by the "Double Your BTC" emails/website

Also Known As: possible malware infections
Damage level: Medium

What is the "Double Your BTC" scam email?

"Double Your BTC" is the name of a spam campaign - a mass-scale operation during which deceptive emails are sent by the thousand. These letters promote a scam website, promising to double the BTC (Bitcoin cryptocurrency) recipients invest in it.

It must be emphasized that all of the information provided by the "Double Your BTC" emails is false. Therefore, by trusting them - users can experience financial loss and possibly other serious issues.

Double Your BTC email spam campaign

The "Double Your BTC" scam emails inform recipients that they can double their Bitcoins in twelve hours. The letters promote a website offering this fake service, which is supposedly fully automatic and operates with no human involvement. The link in these emails redirects to a bogus site.

The text presented in this webpage repeats the promise of doubling Bitcoin cryptocurrency users transfer to its service. Instead of the process allegedly taking twelve hours - the site states that it takes twenty-four.

The page also contains false information on how many transactions it has doubled and the total sum paid out.

The smallest investment users can make is 0.005 BTC (worth approximately 200 USD), the largest - 10 BTC (approx 500 thousand USD); note, exchange rates fluctuate, so the conversions are likely to be inaccurate in the future.

As mentioned in the introduction, the claims made by the spam emails/ scam website are false. Therefore, regardless of how much users "invest" in the "service" - they will receive nothing in return and only experience financial losses.

Spam campaigns are used for various scams, phishing, and malware (e.g., trojan, ransomware, etc.) proliferation.

The deceptive emails are usually disguised as "official", "urgent", "important", "priority", and similar. "MOBI GRAND TELECOM Lottery", "Clustered E-mails Pending", "cPanel Email Scam", "U.S Army Special Operations Command Consignment" - are some examples of spam campaigns, and "Double Your Bitcoins", "Doge Giveaway", "Generate Bitcoin" of online schemes similar to "Double Your BTC".

Regardless of what scam letters claim, offer, request, or demand, the end-goal is always the same - to generate revenue for the scammers/ cyber criminals behind them. Due to how prevalent such mail is, it is highly recommended to exercise caution with incoming emails.

How do spam campaigns infect computers?

Systems are infected via malicious files distributed through spam campaigns. The files can be attached to and/or linked inside the deceptive emails. Virulent files can be in various formats (e.g., Microsoft Office and PDF documents, archives, executables, JavaScript, etc.), which upon opening - initiate malware download/installation. For example, Microsoft Office documents infect systems by executing malicious macro commands. This process begins the moment a document is opened - in Microsoft Office versions released after 2010. Newer versions have "Protected View" mode that prevents automatic execution of macros. In these versions, users are asked to enable editing/content (i.e., macro commands) and alerted of the potential risks.

How to avoid installation of malware?

Suspicious and irrelevant emails must not be opened, especially any attachments or links present in them. It is also advised to use Microsoft Office versions released after 2010.

Aside from spam campaigns, malware is commonly proliferated via untrustworthy download sources (e.g., unofficial and free file-hosting websites, Peer-to-Peer sharing networks, and other third-party downloaders), illegal activation tools ("cracks"), and illegitimate updates.

Therefore, it is recommended to only use official and verified download channels. Additionally, all programs must be activated and updated with tools/functions provided by legitimate developers. It is crucial to have a reputable 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 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.

How to remove malware manually?

Manual malware removal is a complicated task - usually it is best to allow antivirus or anti-malware programs to do this automatically. To remove this malware we recommend using Combo Cleaner Antivirus for Windows.

If you wish to remove malware manually, the first step is to identify the name of the malware that you are trying to remove. Here is an example of a suspicious program running on a user's computer:

malicious process running on user's computer sample

If you checked the list of programs running on your computer, for example, using task manager, and identified a program that looks suspicious, you should continue with these steps:

manual malware removal step 1Download a program called Autoruns. This program shows auto-start applications, Registry, and file system locations:

manual malware removal step 2Restart your computer into Safe Mode:

Windows XP and Windows 7 users: Start your computer in Safe Mode. Click Start, click Shut Down, click Restart, click OK.

During your computer start process, press the F8 key on your keyboard multiple times until you see the Windows Advanced Option menu, and then select Safe Mode with Networking from the list.

Your PC will restart into the Startup Settings screen. Press F5 to boot in Safe Mode with Networking.

manual malware removal step 4In 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.

Click 'Options' at the top and uncheck 'Hide Empty Locations' and 'Hide Windows Entries' options

manual malware removal step 5Check 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".

locate the malware file you want to remove

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.

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 Combo Cleaner Antivirus for Windows.
