The Steps to Prevent a Virus on a Windows Computer

Leave a Comment

Prevention of a virus is much easier to accomplish than repair. When a computer breaks down, the entire system crashes and wipes out everything including the Windows   application. System. although sometimes Windows is not involved. It really depends upon the virus attacking the system. There are several steps of prevention   that are simple and reduce the amount of work that a repair would so partake.

One important measure to take for the prevention of a virus on a computer system is to not open e-mails or advertisements that are from an unknown sender. When a user does open  these sites, his/her computer is at risk of being exposed to a virus, which can basically wipe out all related ,material, dependent upon the type of virus and extent of its damage. Any material that is stored on a Window application is definitely in danger of also being lost.

Another preventive step is to have all files backed up on CD’s or if   an individual would rather print hard copies, these files could be backed up the traditional way.

Another way of the prevention of a virus is to have a good antivirus application downloaded to run on a daily basis, in a consistent manner. Some individuals run an anti virus application two times a day, while others may prefer more than one type of antivirus application daily.

There are many antivirus applications that can be downloaded free of charge, or that have a free trial offer that can be used for a limited amount of time. A computer should be checked for virus infiltration regularly to ensure that a virus has not gone undetected. Viruses can linger and do extensive damage if not caught in the early stages.  This is why it is important to keep on top of the situation regarding computer safety, thus implementing the proper precautions relating to the prevention of a virus.

If there is a problem with any application system, including Windows, and a virus is suspected, one should immediately seek assistance from one of the following means;

  • Consult an online Tech desk
  • Research and follow the steps of an virus removal  kit
  • Call and talk to a repair technician who  will lead  you step by step through  wiping out a virus
  • Take an infected system to  a local computer repair shop,
  • Download antivirus applications for future uses.

If, by chance, one procedure is unsuccessful, another should be quickly implemented to bring the system back to normal as quickly as possible.   The longer that the virus is untouched, the more damage that it can and probably will cause.

If the Window application system is affected by a virus, there are several possible ways that this system can be restored, After the virus is  cleared, repair options include a system  restore feature, a Troubleshooting application, a new version of Windows, etc. It is then imperative to   seek professional help from a technology specialist if the Windows application is not properly working so that the prevention of a virus is possible.

How to Remove the Conficker – Downadup – Kido Worm

Leave a Comment

The new worm blast that affects almost all Windows versions listens to the name of Conficker or Downadup or Kido. It is estimated that around 50000 computers per hour are being infected with the Conficker worm all over the world. This worm spreads itself by exploiting the Microsoft vulnerability MS08-067. It is a very clever malware as it tries to break passwords by brute force attacks in order to take administrator access to the infected machines. It uses also network shares to copy itself over to other hosts. The worm code is so complicated that researchers are aggressively digging into it in order to engineer a cure for it. The new version of the worm is Conficker C and as known so far, on April 1st all the infected hosts will be taken under the control of a secret master bot network.

To remove the worm, first you need to patch your windows machine for vulnerability MS08-067. After that, you need a solid antispyware tool. You can download XoftSpySE below for a free scan of your computer for Conficker Worm

Virus Evolution History Part 2 – Melissa and other executable worms

Leave a Comment

The powerful file interpreter scripts included in Microsoft Office gave to the virus creators an opportunity to be armed with the characteristics of worms. An example of this was Melissa worm, a Word macro virus with the characteristics of a worm, which infected documents created with the 97 and 2000 versions of Word. This worm automatically sends itself as an attachment in an email, in the first 50 contacts to be found in the address book in Outlook, on the infected computer. This technique, which unfortunately has become very popular today, was first used in this virus which in 1999 caused one of the biggest epidemics in computer history, within a few days. In fact, large companies like Microsoft, Intel and Lucent Technologies had to block their connections to the Internet due to the action of Melissa.

The technique applied for the first time in the Melissa virus was developed subsequently by viruses like VBS / Freelink who, on the contrary to its predecessor, sent itself to all contacts recorded in the address book of an infected PC. This was the beginning of a new generation of worms, that were able to send themselves to all the contacts found in the address book in Outlook of the infected computer. From all those worms, the one that really stands out is the VBS / LoveLetter, widely known as I love You Virus, which first appeared in May 2000 and caused an epidemic with losses estimated at 10,000 million euros. To attract the attention of users and to contribute to its spread, this worm sent itself via an e-mail message with ILOVEYOU title and an attachment named LOVE-LETTER-FOR-YOU.TXT.VBS. When the user opens the attachment, the computer was infected.

Besides Melissa, in 1999 another type of virus appeared, which was also a milestone in the history of viruses. In November of that year the VBS / BubbleBoy virus (written in VB Script) was created: a new type of worm which spread over the Internet, without the user clicking on an attachment. To automatically run itself when the user opened or displayed a message, the virus took advantage of a security problem in Internet Explorer 5. Successor of this worm in 2000 was the JS / Kak.Worm, which spread by exploiting the automatic signature of Microsoft Outlook Express, which enabled it to infect computers without requiring the execution of a file from the user. These were the first samples of a series of worms that were subsequently enriched with new members – worms that could attack computers while users were browsing the Internet.

Virus Evolution History – Part 1

In this article we will examine how the growth of Windows and Visual Basic affected the evolution of computer viruses, since along with the development of those two technologies we had the appearance of global virus epidemics, like the virus Melissa in 1999.

While Windows were evolving as an application designed to facilitate the management of the DOS in a 32-bit operating system, the virus developers returned to using assembly as the main programming language to create viruses. Versions 5 and 6 of Visual Basic (VB) were, together with the Borland Delphi (Pascal language environments for Windows), the preferred development tool for creators of worms and Trojan horses. Then Visual C came into play, which offered a powerful application programming language for Windows. Quickly C was adopted by the creators of viruses, Trojan horses and worms. Viruses based on the Visual C language acquired unprecedented power, supplanting all other types of viruses. Although the characteristics of worms have changed with time, all have the same goal: to spread to as many computers in the shortest possible time.

Over time, Visual Basic became extremely popular and Microsoft implemented it as part of the functionality of a separate tool: an “interpreter” capable of executing script files that contained code with similar syntax.
Simultaneously, with the establishment of the 32-bit Windows platform, the first script file viruses were born: These were hostile software hidden inside a plain text file. Script file viruses showed that the executable files (files with extensions. EXE and. COM) were not the only ones that could carry viruses. As we have already seen with BAT files for viruses, there are other means of spreading a virus, fully justifying the assumption that everything that can be executed either directly or through an interpreter, may contain a hostile software. Specifically, the first viruses that could infect the macros contained in the applications of Microsoft Office came into the scene. As a result, Word, Excel, Access and PowerPoint have become vehicles for the spread of lethal weapons, which destroy data even when users simply open a document.
