Viruses are nothing new for experienced Internet users. These pesky worms infect computers in a variety of different ways, and constantly evolving programs mean there are always new threats to combat. The netsky.d virus is one such example. This is just one of the many different packages of malicious code operating under the nestky family of viruses, and can cause the system to run ineffectively, mess with the computer’s audio output, and copy itself to other individuals through your address book.
Netsky viruses have a variety of different names, though the netsky.d variant is typically known as w32.netsky.d, or some combination of this thread and other words. It effects computers running Windows, and spreads through email, just like the other viruses in its family. Computer users often times continue to user their machine without realizing that the netsky.d virus has successfully infiltrated their machine, though symptoms such as random beeping and beeping on specific days can serve as indicator that the machine has been compromised.
Once a netsky virus has succeeded in entering a computer, it copies itself to all of the email addresses available in the computer owner’s contact book. A telltale netsky email will have a very short subject line and a short message contained within the email. Furthermore, an attachment will claim to contain a greeting card, message, or document, but instead will execute the virus on the system on which it has been opened.
One specific characteristic of the netsky.d virus is that is creates a copy of itself as “WINLOGIN.EXE” and places the file in the Windows folder. Some examples of the virus send through blind carbon copy (BCC), while others may target users on an individual basis. Much like other variants within the same family, the netsky.d virus also contains an SMTP engine, allowing it to spam the contacts on your system without the use of a third-party email application.
While netsky viruses are certainly an issue for computer owners to be aware of, most antivirus programs should provide protection against these threats. The first virus of this family become rampant in 2004, which has given developers more than ample time to fix the holes the virus exploited. If the virus has still managed to infect a computer, it can be removed with an antivirus program or by downloading a piece of removal software from one of the many reputable antivirus companies.
Preventing infections from the netsky virus and similar threats is largely dependent on carefully scanning the messages received in one’s inbox. Most email authors will include a bit of personal information within their message, either identifying the recipient by name or mentioning what the specifics of the file attached may be. If you are ever suspicious about the contents of an email, the best course of action is to contact the sender and verify that it contains legitimate information. In the event that the email has been sent as part of a viral attack, this notification will also serve to let the other person know that a virus is present on their machine and spamming their contacts.
