It is known that hackers sometimes use the name of wscript.exe to distribute a worm called “VBS_VBSWG.AQ”. This threat has first approached in 2002 and has been targeting English-speaking Windows users. This dangerous worm appears throughout suspicious email messages (via Microsoft Outlook) pretending to send “Shakiras Pictures” that are clipped as an attachment (ShakiraPics.jpg.vbs, 7,995 bytes).

Wscript.exe malware which distributes this worm uses the official name of the original file to reach the targeted system. If a virus is hiding behind this executable, the malicious registry is included in this directory: HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run\. Here are other names of this worm:

  • Shakira, I-WORM.LEE.
  • VBS/VBSWG.
  • VBS.VBSWG.AQ@mm, LEE.

Users find it denying access to the local disk, changing the MSIE homepage, preventing the system from shutting down, etc. As you can see this executable can be misused in different types of ways. Some criminals often hide Trojan horse behind .exe files.

Mostly, users do not pay much attention to executables, unless they start bothering and interrupting successful computing work. If a Trojan virus is distributed via wscript.exe, there might be no particular signs of infection at first. However, high CPU usage, two similar processes running, software crashes, unrecognizable files installed, might be the symptoms of a Trojan horse attacking the system.

We recommend removing wscript.exe if it is a malicious file that has been distributing on your system lately. If you are not sure about its legitimacy, you can always use reliable computer software to scan the system and search for malware traces.

Malware distribution and avoiding tactics

Malware such as trojans, worms, cryptominers, ransomware, and other threats can be brought to the system in different ways. However, the most common method to plant malware onto a specific machine is by distributing it via email spam. For more details, the malicious payload comes as a suspicious attachment or hyperlink.

Mostly, executables or other types of files/documents are used for malware spreading. You have to carefully run a check through your received emails and investigate all attachments for possible malicious traces before opening them. This can be done even better with the help of a reliable antimalware/antivirus program.

Furthermore, do not leave any outdated software on your computer. Especially, perform all recommended updates for your operating system and antivirus software so that malware will be less capable of bypassing your security barrier. Additionally, avoid visiting questionable software-downloading, gambling, movie-watching, or adult-themed websites where trojans and similar threats can be injected into hyperlinks and ads.
