Trojans are known to impersonate legitimate processes and CoreSync.exe (a legitimate Adobe process) is their latest victim. A coin-mining Trojan uses this name to camouflage its malicious processes.

The CoreSync Trojan is a menace that corrupts your computer and uses its resources for coin mining. The parasite forces your machine to run heavy processes that burden your CPU and GPU. These operations can be quite profitable. The revenue, however, is not for you but for the Trojan’s operators. You are left only with the side effects and the potential risks! CoreSync takes everything your computer has to offer and spares nothing for you and your programs. The parasite makes your operating system sluggish and unresponsive. It causes your apps to load slowly and crash frequently. It is behind countless odd errors and crashes. The Trojan could also force you to reboot your computer repeatedly.

How did I get infected with?

CoreSync Trojan sneaks into your computer and wrecks your OS. Don’t, however, imagine cyber-attacks. This Trojan spreads through mass-distribution tricks, not through targeted attacks! It travels the web hidden in malicious bundles, spam messages, corrupted links, and, of course, pirated software. The parasite relies on trickery and prays on naive users. CoreSync Trojan lurks in the shadows and infects your PC when you throw caution to the wind. Don’t give into naivety! No anti-virus app can protect you if you act that recklessly. Your diligence is the key to a secure and infection-free computer. Only your actions can prevent infections, so don’t be lazy. Always take the time to do your part. Don’t visit dodgy websites. Download software and updates from reputable (preferably official) sources only. And, of course, be very wary of your inbox. Whether it’s an instant message or email, treat all unexpected messages as potential threats. Always verify their senders. If, for example, a company or organization unexpectedly contacts you via email, go to their official website. Compare the email addresses listed there to the questionable one. If they don’t match, delete the pretender immediately. You can also double-check the suspicious senders by entering their handles or addresses into a search engine. If they were involved in shady activities, someone might have complained online.

Why is this dangerous?

CoreSync Trojan is a complete and utter menace. It sneaks into your computer and wrecks everything. It alters settings, modifies the registry, drops files, starts malicious processes. This, of course, happens in complete silence. The virus corrupts your OS without triggering any alarms. You can’t catch it in time to limit its corruption. Everything, however, changes once the virus gets your device under control. CoreSync affects every aspect of your user experience. It makes your operating system sluggish and unresponsive, causes your apps to malfunction, triggers errors and crashes. You can’t so much as browse your favorite websites without encountering problems. Don’t, however, mistake these performance issues for the essence of the problem. These are just symptoms of the infection. You risk ending up with a wrecked machine and an expensive electricity bill! CoreSync doesn’t limit its resources consumption but exploits your CPU. It doesn’t pause its mining processes even when your CPU’s temperature reaches dangerously high levels. Such prolonged mining leads to irreparable hardware damage. Not to mention that it affects your electricity bill. The coin mining operations are profitable only if you don’t use your own resources. CoreSync uses yours! The Trojan’s operators make a mint at your expense. Don’t become their sponsor. Remove their parasite ASAP! Find where CoreSync lurks and delete it for good!
