In recent days, a rapidly increasing number of users have started reporting infections on their computers by a malicious software program that goes under the name of check. According to the reports from cyber-security experts, check can be categorized as a Trojan horse.


As you probably already know, this nasty group of PC viruses is one of the most widespread and problematic types malware. What you need to know about Com.realme.securitycheck in particular is that it is one of the latest additions to the Trojan horse malware class and as such is likely to be highly-advanced and very dangerous. It is important that each and every one of our readers is well informed about the specific characteristics of Com.realme.securitycheck as this is an important factor when it comes to protecting one’s computer against such infections.

In the next lines, you will be introduced to check and you will learn what you could expect from such a virus. Also, you will be provided with a reliable and detailed instructional manual that will guide you through the process of eliminating check from your machine in case the virus has already infiltrated the computer. However, we recommend you first take a couple more moments to read the remainder of the article so as to learn more about the specifics of the virus – this will not only help you with its removal but will also make it easier for you to protect your machine against similar cyber-threats in the future.

The Trojan horse malware class

Viruses like check are really stealthy and are oftentimes able to get inside the system of the targeted machine without showing any signs of their presence. Once inside, the malware could gain Administrator-level privileges and form there it might be able to execute all kinds of insidious and harmful tasks without the user having any idea about what is actually happening within their machine. Unfortunately, in many instances, by the time the targeted victim finds out about the ongoing infection, the virus’ tasks has already been completed and there’s little that could be done to revert whatever the malware has done. However, this certainly doesn’t mean that you shouldn’t be watchful and vigilant – in many instances the user’s attentiveness might make the difference between intercepting a virus like check on time and allowing it to silently complete its criminal agenda.

Although Trojan horse symptoms aren’t too common and might sometimes be difficult to spot or might be confused with other PC issues, there are still certain red flags you need to be on the lookout for. For instance, increased RAM, CPU and GPU memory use as well as sudden freezes, slow-downs, crashes and system errors could give away a Trojan horse infection. To help yourself detect such viruses, you could also equip your computer with a strong security program like an antivirus/anti-malware tool. Just remember that the fact that you have such a program on your machine doesn’t mean that no virus could get to it.

That is why your best bet when the security of your computer is concerned is to simply avoid interacting with potential malware sources. Such sources normally are spam messages to your e-mail or social network accounts, misleading and fake online ads (especially ones coming from sketchy sites), questionable and pirated software downloads, illegal webpages, etc. All in all, you must take the safety of your system in your own hands or else the chances of landing some nasty virus like check would be higher than you’d prefer them to be.

Damage and harm

There isn’t one specific thing that Trojan horse viruses are typically used for. Instead, those malicious programs are typically multifunctional and could be programmed and re-programmed to execute different tasks. For instance, a Trojan might spy on its victim or inflict severe damage upon the infected system. It might also be able to backdoor other viruses inside the victim’s machine – ransomware viruses oftentimes get loaded inside users’ computers with the help of a Trojan.

Another possible thing a malware like check might be able to do is steal information from the infected computer or even force the machine to mine for Bitcoin or for some other cryptocurrency. In some cases, your PC might even get forced to take part in Denial of Service campaigns or spam e-mail campaigns. There are other possibilities as well but we won’t be listing them all here as there’s no need for that. The important thing that you should all take from this paragraph is that Trojans are typically highly-threatening cyber-hazards and need to be removed from the infected machine ASAP in order to avoid a variety of potential issues that might arise from such an infection.
