CoreSync Virus


If the location of CoreSync.exe is in a subfolder of the Windows folder for temporary files, then this mean that your system has been compromised to a Trojan Horse virus.


The CoreSync Virus is a Cryptocurrency Miner.

CoreSync is categorized as a Trojan Horse and has been specifically created to cause damage to the infected computer. In most cases, CoreSync can provide the hackers with remote access to the infected computer and let them manipulate different system processes. The Trojan Horse viruses are pretty common online infections. Yet the majority of web users still don’t know much about these terrible threats. For instance, we have received a number of messages from users who have been infected with one of the new Trojan Horse variants called CoreSync. The users have been asking questions about how to deal with the infection and what to expect from it. That’s why we’ve come up with the current article and the removal guide that you can find below. But before you go to the instructions there, we suggest you read the information that follows to learn a bit more about what Trojans like CoreSync might be able to do.

A key feature of all Trojan Horse viruses is the fact that they can hardly be detected by regular web users without the help of a strong security program. That’s what makes infections like CoreSync a preferred tool for any hacker or cybercriminal. As a matter of fact, a Trojan can go unnoticed for weeks, or maybe even months, so it’s great that you actually got to know about the presence of CoreSync on your computer. Sadly, we can’t tell you what kind of harm to expect from the infection since one of the qualities of the Trojans has to do with their versatility. With the help of a program like CoreSync, a hacker can do anything from data theft and espionage to total system destruction, and more.

CoreSync.exe is the name of a cryptojacking Trojan horse and should not be mistaken with the genuine CoreSync.exe file which is a software component of Adobe Acrobat by Adobe. The location of the malicious CoreSync.exe file will be in a temporary file folder.

One of the possible uses for Trojan-based programs is for malware distribution and delivery, so the presence of CoreSync on your computer can lead to potential infection with Ransomware, Spyware, and who knows what else. A Trojan can also be used to turn your computer into a bot and allow the hackers to control it remotely without you even suspecting it. You may become a subject of 24/7 surveillance, a victim of money theft or theft of valuable information which not only can be sent to the hackers’ servers but also could be destroyed after that.
