What is wscript.exe?

Wscript.exe is a file that belongs to the Microsoft Windows operating system, it is a part of it. Wscript.exe is also known as Windows Script, a service that is designed to provide Windows system with scripting abilities. Unfortunately, cyber criminals often use names of legitimate processes, files to disguise malware. It is possible that the wscript.exe might be used for this purpose too.

wscript.exe malware

Typically, the wscript.exe executable can be located in "C:\Windows\System32", a Windows folder that contains operating system's files. However, if wscript.exe's name would be used to disguise malware, then this file would be placed in some other folder, or/and it would have a different name. For example, wcript.exe. Typically, cyber criminals give very similar names so the files would look like legitimate ones/would not be suspicious. Besides, when a malicious process is running in Task Manager it usually has some graphic icon next to it, when it actually supposed to have a system icon. It is worth mentioning that sometimes virus detection engines detect legitimate files as threats (provide false positive results), it usually happens due to errors/mistakes in databases. Luckily, these issues get fixed quickly. However, in some cases it goes other way around: malicious files, if named as legitimate system files, bypass virus engines and infect computers. These malicious files could be used to infect computers with high-risk malware that might be designed to steal sensitive, personal details (passwords, logins of personal, banking accounts and so on), log keystrokes, spread other viruses etc. Simply said, such programs might cause people data, financial loss, privacy, browsing safety issues and a variety of other problems. If a computer is infected with a program of this type, it should be eliminated as soon as possible.

Cyber criminals use names of various legitimate processes/files to disguise malicious files. A couple examples of files that could also be used to disguise malware are csrss.exe, msfeedssync.exe and gwx.exe. We recommend to make sure that detected files are real threats and only then to remove them. Otherwise it might lead to loss of legitimate files that belong to the operating system.

How did wscript.exe infiltrate my computer?

There is more than one way to distribute/proliferate malicious files and programs. Most of the times cyber criminals do it using spam campaigns, fake software updaters, trojans, software 'cracking' tools or untrustworthy software download sources. If they use spam campaigns for that, then they send emails with files attached to them. Those attachments usually are MS Office documents, archive files, PDF documents, executables (like .exe), JavaScript files and so on. If opened, these files download and install malware. Fake software updating tools infect systems either by downloading and installing malicious programs instead of installing updates, or by exploiting bugs, flaws of installed and outdated software. Trojans are malicious ones programs, in order to cause any damage they must be already installed. Once installed, they cause downloads and installations of malware. Activation ('cracking') tools are programs that allow to illegally bypass activation of software that is not free. However, there are many cases where cyber criminals are designers of these tools and use them to proliferate malware. Third party downloaders, freeware download websites, free file hosting websites, Peer-to-Peer (P2P) networks such as eMule, torrent clients and other unreliable download sources are often used to present infected files as legitimate ones. People who download and open them, cause installations of malicious programs by themselves.

How to avoid installation of malware?

Avoid opening attachments or links that are included in irrelevant emails that are received from unknown, suspicious addresses. Emails of this type should not be trusted and their contents (web links, attachments) opened. Download software from official, trustworthy websites. We do not recommend to any of the tools that we mentioned above. Furthermore, keep installed software up to date, however, it should achieved using tools or functions that are provided by official software developers only. Do not use third party tools to activate software. It is illegal and often causes damage to the system (infects computers). Have a reputable anti-virus or anti-spyware software installed and perform regular virus scans with it. If you believe that your computer is already infected, we recommend running a scan with Spyhunter for Windows to automatically eliminate infiltrated malware.
