WSH virus removal guide
What is WSH?
WSH (also known as WSHRAT) is the name of a remote access/administration trojan (RAT). Typically, cyber criminals use software of this type to control victims' computers remotely. In this way, they can steal personal details and data, which is then used to generate revenue in various ways. WSH is a powerful RAT that can cause users of infected computers serious problems. If there is reason to believe that WSH is installed on your system, remove/uninstall it immediately.
WSH can be purchased by anyone from the wshsoftware[.]site website. This RAT can be used to steal passwords that are stored on victims' web browsers and email clients. Therefore, cyber criminals can use WSH to steal personal accounts and misuse them for malicious purposes. For example, to send scam emails, trick people into making money transactions, make fraudulent purchases, and so on. Furthermore, cyber criminals can use WSH to install malware on the victim's computer. This RAT can download, upload, and execute files. It is also capable of executing remote scripts and commands. In summary, WSH can be used to infect the victim's computer with malicious software such as ransomware, various Trojans, and other high-risk malware. People with computers infected with ransomware often cannot access their files, since these programs encrypt them using strong encryption algorithms. Typically, the only way to decrypt files is to use software held only by the cyber criminals who designed the ransomware. To get that software, victims must pay a ransom. Furthermore, WSH includes a keylogging feature and thus can be used to record each key pressed. Typically, cyber criminals use keyloggers to steal passwords and other personal details. To avoid damage caused by the WSH remote access trojan/tool, you are strongly advised to remove it immediately.

There are many different RATs online. Some examples are InnfiRAT, Gh0st, and AsyncRAT. Different tools might have different capabilities. In any case, these programs are used to steal personal details, infect computers with other malware, steal accounts, take screenshots and control computers remotely in other ways. Victims usually experience problems relating to data, monetary loss, privacy, browsing safety, and so on.

How to avoid installation of malware
Do not open web links or files that are attached to irrelevant emails, especially when the emails are received from unknown, suspicious addresses. Neither attached files nor web links that lead to malicious files can infect systems if they remain unopened. Download your software from official, trustworthy websites. Other channels such as Peer-to-Peer networks, unofficial pages, third party downloaders, etc., should not be trusted. Installed software should not be updated through unofficial tools. Use tools or implemented functions provided by official developers only. Licensed (paid) programs should not be activated using unofficial tools - it is illegal to bypass paid activation using 'cracking' software. Furthermore, this often leads to installation of malware. Keep computers safe by having reputable anti-spyware or anti-virus software installed and scan the operating system with it regularly. If you believe that your computer is already infected, we recommend running a scan with Malwarebytes for Windows to automatically eliminate infiltrated malware.

How to remove malware manually?
Manual malware removal is a complicated task - it is usually best to allow antivirus or anti-malware programs to do this automatically. To remove this malware we recommend using Malwarebytes for Windows. If you wish to remove malware manually, the first step is to identify the name of the malware that you are trying to remove. Here is an example of a suspicious program running on a user's computer:
If you checked the list of programs running on your computer, for example, using task manager, and identified a program that looks suspicious, you should continue with these steps:
Download a program called Autoruns. This program shows auto-start applications, Registry, and file system locations:
Restart your computer into Safe Mode:
Windows XP and Windows 7 users: Start your computer in Safe Mode. Click Start, click Shut Down, click Restart, click OK. During your computer start process, press the F8 key on your keyboard multiple times until you see the Windows Advanced Option menu, and then select Safe Mode with Networking from the list.

Extract the downloaded archive and run the Autoruns.exe file.
In the Autoruns application, click "Options" at the top and uncheck the "Hide Empty Locations" and "Hide Windows Entries" options. After this procedure, click the "Refresh" icon.
Check the list provided by the Autoruns application and locate the malware file that you want to eliminate.
You should write down its full path and name. Note that some malware hides process names under legitimate Windows process names. At this stage, it is very important to avoid removing system files. After you locate the suspicious program you wish to remove, right click your mouse over its name and choose "Delete".
After removing the malware through the Autoruns application (this ensures that the malware will not run automatically on the next system startup), you should search for the malware name on your computer. Be sure to enable hidden files and folders before proceeding. If you find the filename of the malware, be sure to remove it.
Reboot your computer in normal mode. Following these steps should remove any malware from your computer. Note that manual threat removal requires advanced computer skills. If you do not have these skills, leave malware removal to antivirus and anti-malware programs. These steps might not work with advanced malware infections. As always it is best to prevent infection than try to remove malware later. To keep your computer safe, install the latest operating system updates and use antivirus software.
To be sure your computer is free of malware infections, we recommend scanning it with Malwarebytes for Windows.
