Random Command Prompt Pop-Ups removal instructions
What is Random Command Prompt Pop-Ups?
Some users continually encounter Command Prompt randomly popping-up and disappearing without any apparent reason. This is very frustrating and inconvenient when gaming, working, and performing intensive tasks on the computer. Furthermore, these pop-ups typically indicate a computer infection - in most cases, Command Prompt is opened by various adware-type programs and, sometimes, by ransomware.
During computer operation, users continually encounter the Command Prompt window, which automatically appears and disappears. Many people do not realize that this is performed by applications (typically, malware) that run in the background. These programs open the Command Prompt, immediately run a number of commands, and then close the window before the user is aware of what happened or can take any action. This is typically done with the intention of modifying various system settings without users' consent, or to update certain data/malware. Note that there are situations where random Command Prompt pop-ups are displayed by legitimate software (e.g., Microsoft Office installer, which resides in Task Scheduler's library). Mostly, however, these pop-ups are caused by computer infections. If who you encounter these windows, immediately eliminate all suspicious applications/browser plug-ins and scan the entire system with a legitimate anti-virus/anti-spyware suite. We also recommend that you disable the "Get Office" tool (which installs automatically) in the Task Scheduler.
To disable "Get Office", follow these steps:
- Click "Start", type "Task Scheduler", and click on this result
- On the left side of the opened window, click the small 'arrows', and follow this path: Task Scheduler Library -> Microsoft -> Office
- After selecting the Office folder, find the "OfficeBackgroundTaskHandlerRegistration" task and disable it (in some cases it is also necessary to disable the "OfficeBackgroundTaskHandlerLogon" task)
If the pop-ups were displayed by MS Office installer, they should no longer appear.

You should be aware of the behavior of adware and ransomware. Adware is a form of unwanted software that delivers various intrusive advertisements (coupons, banners, pop-ups, etc.) These apps deliver intrusive ads using various tools that enable placement of third party graphical content on any site. Therefore, displayed ads often conceal underlying website content, thereby significantly diminishing the browsing experience. Furthermore, they might lead to malicious websites or even run scripts that download and install malware. Therefore, even a single click can result in high-risk computer infections. Adware-type apps also gather sensitive information that developers later sell to third parties. The information can include IP addresses, geo-locations, website URLs visited, pages viewed, search queries, keystrokes, etc. The data typically includes personal details that cyber criminals misuse to generate revenue, thus causing serious privacy issues or even identity theft. Ransomware is much more complicated. It typically corrupts stored most files on the computer system. To achieve this, ransomware-type viruses employ various symmetric/asymmetric encryption algorithms (e.g., RSA, AES). These algorithms generate unique encryption/decryption keys, and thus restoring files without them is impossible. Ransomware developers hide these keys on remote servers and make ransom demands for their release. Victims must pay hundreds or even thousands of dollars for decryption. Even if victims agree to pay, however, they typically receive no benefit - cyber criminals simply ignore victims, once ransoms paid.
Adware-type apps often claim to provide various "useful features", however, since their only purpose is to generate revenue for the developers, they deliver no value for regular users. These potentially unwanted programs (PUPs) pose a direct threat to your privacy and Internet browsing safety.
How did potentially unwanted programs install on my computer?
Malware is distributed in various ways. Adware-type viruses are typically distributed using intrusive ads, together with a deceptive marketing method called "bundling" (stealth installation of third party applications together with regular software). "Bundled" apps are hidden within various sections (e.g., "Custom/Advanced" settings) of the download/installation processes. By clicking intrusive ads and skipping download/installation steps, many users open doors for adware to enter the system, whilst ransomware-type viruses are often distributed using spam emails (infectious attachments), third party software download sources (freeware download websites, free file hosting websites, peer-to-peer networks, etc.), fake software updaters, and trojans. Once opened, malicious attachments stealthily download and install malware. Unofficial download sources proliferate malware by presenting it as legitimate software - users are often tricked into downloading and installing viruses. Fake updaters infect the system by exploiting outdated software bugs/flaws. Trojans are the simplest ones - they open "backdoors" for malware to infiltrate the system. Essentially, the main reasons for computer infections are poor knowledge and careless behavior.
How to avoid installation of potentially unwanted applications?
The key to computer safety is caution. Therefore, pay close attention when browsing the Internet (especially, when download/installing software). Most intrusive ads look legitimate. Once clicked, however, they redirecting to dubious sites (gambling, pornography, etc.) If you encounter these redirects, immediately eliminate all suspicious applications and browser plug-ins. Furthermore, download your applications from official sources only and, preferably, using a direct download link (third party downloaders/installers often promote rogue software). When downloading/installing, carefully observe each step and opt-out of all additionally-included programs. We also recommend that you do not read any emails received from suspicious email addresses and, especially, not to open any attached files. Keep installed applications updated and use a legitimate anti-virus/anti-spyware suite, however, note that criminals proliferate malware via fake updaters. Therefore, your software should be updated using implemented functionality or tools provided by the official developer.
