Win32:Dropper-gen [Drp] Virus

What is Win32:Dropper-gen [Drp]?

Win32:Dropper-gen [Drp] is the generic detection name of various deceptive/malicious applications designed to open "backdoors" for other rogue software (or even high-risk malware). Apps categorized as Win32:Dropper-gen [Drp] are distributed in various ways and infiltrate systems without permission.

After successfully infiltrating the system, Win32:Dropper-gen [Drp]-type apps open "backdoors" for other software/viruses to infiltrate the system. In this way, criminals use these apps to infect the system even more.

Depending on criminals' choice, Win32:Dropper-gen [Drp] can be used to proliferate a wide range of deceptive apps, including adware, browser-hijackers, cryptocurrency miners, or even ransomware and high-risk trojans. Therefore, each instance of of Win32:Dropper-gen [Drp] on a system might have different consequences.

Adware, browser hijackers, and cryptominers are classed as low-risk threats. These apps deliver intrusive advertisements, cause unwanted redirects (thereby diminishing the browsing experience), and diminish system performance. Ransomware and other trojans (which record information, cause chain infections, manipulate systems, and so on) can cause many more issues.

These viruses encrypt data, block access to computers, steal information (account credentials, system information, etc.). Therefore, their presence might lead to serious privacy issues, and significant data and financial loss. If your anti-virus suite has warned you about a Win32:Dropper-gen [Drp] threat, immediately perform a full system scan and remove all detected threats.

Furthermore, eliminate all suspicious applications and browser plug-ins. Note that in some cases anti-virus suites detect harmless applications - the behavior of the software is suspicious, thus leading to 'false-positive detection'. This often occurs when the software is open-source and is implemented with dubious features.

There are many virus-distributing malware available on the Internet including, for example, Hancitor, Emotet, and so on. These so-called "malware droppers" often proliferate just a few viruses at once. If one infiltrates the system, a second infection will clearly follow.

Since Win32:Dropper-gen [Drp] is a generic name in virus databases, we cannot predict which type of malware will be distributed. In any case, the presence of Win32:Dropper-gen [Drp] can lead to serious problems.

How did Win32:Dropper-gen [Drp] infiltrate my computer?

The distribution method used for Win32:Dropper-gen [Drp] depends on its variant. Simple rogue applications are typically proliferated using the "bundling" method and intrusive advertisements. "Bundling" is stealth installation of potentially unwanted applications with regular software/apps.

Developers are not honest enough to disclose "bundled" apps' installation properly and, for this reason, most are hidden within "Custom/Advanced" settings. Intrusive advertisements redirect users to malicious websites and run scripts that download/install rogue apps/high-risk malware.

More advanced variants might be distributed using spam email campaigns, third party software download sources (free file hosting websites, freeware download websites, peer-to-peer [P2P] networks, and so on), and fake software updaters.

Spam campaigns promote malicious attachments (e.g., MS Office documents, JavaScript files, etc.) that, once opened, execute commands designed to download and install malware. Unofficial software download sources present malicious executables as legitimate software, and thus users are tricked into downloading and installing viruses.

Fake updaters infect the system by exploiting outdated software bugs/flaws or simply downloading and installing viruses rather than updates. Essentially, the main reasons for computer infections are poor knowledge and careless behavior.

How to avoid installation of malware?

Caution is the key to computer safety. Therefore, pay close attention when browsing the Internet and downloading/installing/updating software. Carefully analyze each step of the download/installation processes and opt-out of additionally-included programs. Download software from official sources only, via direct download links.

Third party downloaders/installers often include rogue applications, and thus these tools should never be used. The same applies to software updates. Be sure to keep installed applications and operating systems up-to-date, but use only implemented functions or tools provided by the official developer.

Carefully analyze each email attachment received. Irrelevant/unexpected files and those received from suspicious/unrecognizable email addresses should never be opened. Have a legitimate anti-virus/anti-spyware suite installed and running.

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.

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:

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:

 Download a program called Autoruns. This program shows auto-start applications, Registry, and file system locations:

Restart 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.

Windows 8 users: Start Windows 8 is Safe Mode with Networking - Go to Windows 8 Start Screen, type Advanced, in the search results select Settings. Click Advanced startup options, in the opened "General PC Settings" window, select Advanced startup. Click the "Restart now" button.

Your computer will now restart into the "Advanced Startup options menu". Click the "Troubleshoot" button, and then click the "Advanced options" button. In the advanced option screen, click "Startup settings". Click the "Restart" button. Your PC will restart into the Startup Settings screen. Press F5 to boot in Safe Mode with Networking.

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.
