What is Dropbox Update Setup virus?

We have discovered the Dropbox Update Setup while examining various cracked software distribution websites. We have inspected the downloaded "Setup.exe" file and found that it runs in the Task Manager as "Dropbox Update Setup". It causes high CPU usage, which means it may be crypto-mining malware. However, some antiviruses detect it as an information stealer.

More about the Dropbox Update Setup virus

The malicious file distributed via cracked software download pages is named "Setup.exe" (its name may vary). After execution, it starts running in the Task Manager as "Dropbox Update Setup". Dropbox is a legitimate file hosting service. It has nothing to do with the file or process mentioned above.

We have noticed that the "Dropbox Update Setup" process consumes lots of CPU resources. Therefore, it can be assumed that this process belongs to a cryptocurrency miner. Software of this type uses computer hardware to mine cryptocurrency (which consumes more electricity and loads the system thereby rendering it unusable). It is popular among cybercriminals to employ crypto-mining malware to mine crypto using other people's computers.

As we mentioned in the introduction, some security vendors detect the "Dropbox Update Setup" as an information-stealing malware. It is important to know that info stealers can be designed to collect passwords, credit card details, data from web browsers and other apps, clipboard data, etc. Also, they can be designed to log keystrokes (record keyboard input).

Dropbox Update Setup virus in general

"Dropbox Update Setup" is the name of a malicious process possibly belonging to some cryptocurrency miner or an information stealer. Either way, it is not a legitimate process. It is important to mention that cybercriminals can use cracked software download pages to distribute ransomware, remote access Trojans, and other types of malware.

How did Dropbox Update Setup virus infiltrate my computer?

This malware is distributed via websites supposedly hosting cracking tools or cracked/pirated software (note that it is against the law to use pirated software). Also, malware is often distributed using emails (by sending malicious links or attachments) and untrustworthy sources for downloading software/files (like P2P networks, free file hosting sites, and third-party downloaders).

In other cases, cybercriminals aim to trick users into executing malicious drive-by downloads, fake updaters/installers, etc. Either way, they only succeed when users execute malware by themselves.

How to avoid installation of malware?

Do not download files and software from unreliable sources (cracked software distribution pages and other shady pages, P2P networks, etc.). Use official pages and direct links to download them. Also, do not open links or files/attachments sent from suspicious or unknown addresses. Especially when received emails are not relevant.

Keep the operating system and installed software up to date. Use tools or functions provided by the official developers to activate and update the software. If you believe that your computer is already infected, 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.
