Types of Computer Viruses
In computing terminology, a malicious code is a term used for computer viruses and programs designed to cause damage to computers. Other types of destructive PC worms are known as Internet virus including the examples like Worms and Trojans.
Outlined below is the description of different kinds of computer viruses:
Program/File Infector
Falling under the category of parasitic viruses, a program or file infector attempts to infect the files with extension code like .exe, .com, .drv, .dil, .bin, .ovl, and .sys. It gets activate along with the execution of executable file containing virus. The virus then loads itself into memory and replicates itself to other executable files when these files are opened or run.
The File Infector virus can destroy the content contained in files and cause irreversible damage to them. Some file viruses have also operated as email worm and Trojan horse.
The best way to disinfect files infected by the file virus is to delete them and restore from back up.
Macro Computer Virus
A macro computer virus is a virus written in a language built into a software application such as a word processor. For example: Microsoft Office has the macro language built into its application. This is why most of its application programs are affected by macro computer virus.
Macro viruses are generally created using the macro recorder or Visual Basic for Applications. The applications that are the most prone to this antivirus are Word Documents, Excel Spreadsheets, Power Point Presentation, and Access Database. The virus infects templates of these documents and therefore every file that the user opens gets affected. Some common macro computer viruses are Auto Exec, Auto New, Auto Open, Auto Close, and Auto Exit.
The auto macros can be disabled by using the command DisableAutoMacros in any macro that is written. Another way to remove it is by holding down the shift key while opening a document.
Multi-Partite Virus
It behaves in the same way as other computer viruses do. As the name signifies, they are sometimes more than one type. These are hybrids and are known as multi-partite virus.
Polymorphic Viruses
It is a kind of virus which produces different but operational copies for itself. Its attack is considered to be extremely dangerous as virus detectors will not be able to detect all instances of virus attacks simultaneously. And this is one of the reasons why it is known to be strategically designed.
Stealth Viruses
A stealth virus uses different mechanisms to prevent recognition by antivirus software. It tries to escape detection either by redirecting the disk head to head to read another sector or modifying the file size shown in the Directory listing.
Classification of some viruses is not possible as they are the file type viruses which start behaving as computer worms with an activation code.

ASP Web Hosting – Getting an Overview
ASP is known as Active Server Pages. It is known to have a great platform in making dynamic web pages, websites or even web applications. The .NET platform works very well together with the ASP which is Microsofts platform and this is an excellent tool for programmers to use.
ASP Web Hosting
The benefits for ASP web hosting are many, such as being able to create the sophisticated and dynamic web sites and applications that are compatible with all the browsers. Even if PHP has been more commonly used as it is platform for the blogging sites such as Joomia, WordPress, and even Mambo, ASP is still to have more advanced systems and applications, one that PHP simply cant measure up to.
ASP or PHP
Choosing between the either a PHP or a ASP platform is really dependent on the choice of website you wish to have and how much of a budget you can afford. Both are known to be open sourced platforms however and are mostly preferred by an individual, startup companies and even small developers, however there are a lot of things that ASP can do far better the a PHP SQL the only difference is the affordability of the service.
Benefits of ASP
The reason why ASP is one of the best hosting services is that you can potentially harness the Microsoft ASP technology, which with the use of HTML can create an interactive website. The advantage of ASP is that it can create personalized preferences for visitors based on information collected during the last visit of the website visitor, this creates dynamic websites. This is a great web hosting option even for a customer who is business class, as they can optimize the technology of the Active Server Pages for the use of customer service information, for their in-house databases, and some other applications in their websites or intranet.
Support
Since Active Server Pages is popular in web programming and development, they are provided support by most servers from Windows especially the Windows NT. Web pages for ASP can be written in either the Visual Basic of Microsoft or Jscript. All the different version of ASP is also supported by a ASP web hosting service provider, that includes ASP.NET. The most newly updated version is ASP 3.0.
Features
ASP offers a lot of features to name a few are the following:
– Webmail access
– Ecommerce
– Weblogs
– FTP Access
– Photo galleries
– Live Chat
