Trojans are notoriously difficult to detect since in most cases there aren’t any specific symptoms that they tend to trigger. Because of this, we advise you to always have a reliable and strong security program on your computer as this is one of the few relatively effective methods for intercepting attacks from this type of malware. Also, we already mentioned what the most common distribution techniques for Trojans are so make sure to avoid any online content that seems questionable and suspicious.

Hold the Start Key and R –  copy + paste the following and click OK:

notepad %windir%/system32/Drivers/etc/hosts

Type Regedit in the windows search field and press Enter.

Once inside, press CTRL and F together and type the virus’s Name. Right click and delete any entries you find with a similar name. If they don’t show up this way, go manually to these directories and delete/uninstall them:

  • HKEY_CURRENT_USER—-Software—–Random Directory. It could be any one of them – ask us if you can’t discern which ones are malicious.
    HKEY_CURRENT_USER—-Software—Microsoft—-Windows—CurrentVersion—Run– Random
    HKEY_CURRENT_USER—-Software—Microsoft—Internet Explorer—-Main—- Random

Trojan Horse infections

A major factor that plays a huge role when it comes to Trojan Horse attacks is the way such viruses manage to get inside their victims’ computers. Most typical viruses of this type rely on the user making a mistake which would allow the malware to get inside the computer and gain Administrative privileges. Such a mistake could be opening a spam e-mail and downloading its file attachment, agreeing to install a certain (fake) update request that is suggested by some shady website, executing a file that carries the malware (while thinking it is a legitimate piece of software), installing a pirated program that is actually used to distribute the Trojan as well as many other similar actions. The bottom line is that, in most cases, Trojans such as SysWin.exe come disguised as something that initially seems safe and maybe even useful or interesting to the user. Once the infected piece of content gets interacted with, provided that the customer is currently using an Administrator account, the malware would gain the same privileges and would then be able to carry out whatever malicious task it has been programmed to execute. As far as what a Trojan Horse could be programmed to do, here are couple of examples:

  • Such a virus could, as mentioned above, be used to cause severe damage to the infected system by deleting important OS data, messing with the Registry editor, triggering freezes, errors and crashes (Blue Screen of Death crashes are particularly common).
  • Also, a Trojan might spy on you by tracking your keystrokes, taking screenshots from your screen, gathering telemetry data or even looking inside your room through your webcam.
  • Another possibility is when Trojans are used for backdoor purposes. In such a case, the malware could load other viruses inside the targeted machine, a common example here is when Trojans are used as backdoor for Ransomware.
  • Additionally, it is possible that such a malware piece could force your computer to execute tasks such as distributing spam messages to other users, mining cryptocurrencies for the hackers or participating in malicious large-scale campaigns such as DDoS attacks.

Note that those are only some of the potential capabilities of such viruses and oftentimes Trojans van be reprogrammed and repurposed to do something else which is why we cannot really tell you what SysWin.exe’s Virus exact agenda would be in each specific infection instance.
