Scanning an entire file for viruses is slow, and resulting on the computer performance itself. So how to solve it, because we do know scanning is also important things to do. It is referred to using the derogative term grunt scanning. There are four general approaches to improving scanner performance:

Reduce amount scanned. Scanning an entire file is not only slow, but increases the likelihood of false positives, as a signature may be erroneously found in the wrong place. Instead, scanning can be targeted to specific locations based on assumptions about viral behavior.
• Assuming that viruses add themselves to the beginning or the end of an executable file, searches can be limited to those areas. This is called top and tail scanning.
• More complicated executable formats allow an executable’s entry point to be specified. Scanning can be restricted to the program’s entry point and instructions reachable from that entry point.
• If the exact positions of all virus signatures are known, then scanning can be specifically directed to those areas. The assumption here is that all viruses are known, along with their behavior in terms of file location. This is in contrast to the more generic assumptions about virus locations made above. In conjunction with the entry point scanning above, this
is referred to dis fixed point scanning.
• Many viruses are small. The amount scanned in any location can be set according to the size of common viruses. For example, if most viruses are less than 8K in size, then the scanner may only examine 8K areas at the beginning and end of the executable.

Use of scanning-reduction techniques implies that the scanner will no longer see the complete input. The input to a scanning algorithm doesn’t have to be a faithful representation of a file’s contents, however. The algorithms work equally well on an abridged view of the input.
Of the performance-enhancing approaches, reducing the amount scanned is the only approach that directly affects the potential correctness of the result.

Another way to increase or maximize the performance of your computer and in the same time doing precaution is with desktop software monitoring, the software able to track down the software usage.

Lets have look below tips before you choose the best one:
1. Features Quality

Feature is the main thing you should look into buying hosting. Currently, there are so many hosting providers that seek to improve the quality of their features in order to face competition with other providers. If not, the customer confirmed immediately fled to other providers. Well, with this increasing feature, could bind and lock their client not to migrate somewhere else.

So what features should be considered?
Here are the main features you should check in web hosting provider:

- SPACE (Large hosting capacity, the bigger the better).
- Bandwidth (Large load data from either the upload or download, the bigger the better).
- Uptime (For websites not often down list, select the hosting uptime which is stable, at least 98% to the above)
- My SQL (more is better)
- Addon Domains (useful for those who want to have more than 1 domain on 1 hosting account)

2. Price Comparison

Once you see its features, if you do not care about the price issue it does not really matter. Another case if you are really considering this issue, then the best solution other than seeing the features offered is by comparing prices from one provider to another provider. This way you can draw conclusions Which web hosting company you use decent.

But remember! Do not be fooled by cheap price with good features then you take for granted. Conversely, it does not mean it is with the price of cheap web hosting cheap and not necessarily be good, there are other considerations that you should look. Do not forget also a price that is usually temporary. Usually some web hosting provides cheap prices only in the first year alone. Medium time extension prices soaring, you’ll want to ask this problem.

3. Number of Clients

Number of clients is a reflection of a hosting judged good or bad by his client. More and more clients, the hosting company usually reliable quality. For that, it would not hurt you also ask this problem to the relevant customer service.

4. Match Requirement

Do not be fooled by hosting also provides versatile features unlimited and that provider has been trusted by clients.
Which means what?

Purchase (rent) hosting your online business needs. Because it would be useless if you require only 50 MB of which only worth several dollar rather than buying others cause you’re tempted unlimited features that you won’t used with higher price. Certainly a far cry from the price comparison, and a lot of unused space will be wasted. Unless you intend to make a lot of websites at once or for long-term business, which does require a large space.

5. Server Location

If you target your marketing in certain countries. We recommend that you have to adjust with the provider you use. Because this will affect the speed of access to your target in question. If they are too long to wait for your web loading, it is not impossible they just run away. Usually the USA servers are lighter and can be easily accessed around the world.

6. Support

The characteristics of web hosting that is professionally managed support is responsive, patient, and always online 24 hours a day 7 days a week. Especially if you’re new to dealing with hosting issues, usually a lot of obstacles you will encounter. This is where the function of the responsive support it means a lot. You will be assisted until your site has really online. They usually also provide a complete range of communication media such as IM, email, phone, or directly come to the place.

7. Complete Address

As mentioned earlier, a good web hosting provider usually also indicate the completeness of the address. Although the client does not have to come into place, but at least will make the client feel safe with that address, so they need not fear that provider only fictitious or afraid to be left vague at times.

8. Company Age

The more older the age of the web hosting provider, usually the more experienced they are dealing with hosting issues.
Old age also showed the higher their flying hours to handle the hosting. They maintain strict program, the software until the contents are allowed to use. Because there is rarely a hosting provider out of business due to not be able to manage their hosting.

Last but not least, everyone would dream on fast hosting with age, then try out fasthosts. Great price and offer other features such as free scripts, site builder, and many more, it is mention on ipage host review.

The list below offers tips on what you should do:
• Have real users test your software product. You may think you have created an easy-to-use intuitive piece of software, yet in the end it is not you who decides this. If you plan on selling software online successfully, you need to have real people test it to see how quick they understand how it works and learn how to use it. Not to mention their help in squashing the bugs you might have never noticed on your own, thus making your product as error free as possible.

• Provide an accurate description of the software product. You need a clear and short description of what the software is and what it is used for, so that people can see whether they need it or not. Additional details should be provided somewhere else for those who really wish to know more.
• Make screen shots available. They say a picture makes a thousand words, so screen shots are a very helpful tool when selling software online. The screen shots tell the users if the software product has a well designed interface and let them get a good look at the menu bars and toolbars, for instance, which helps them quickly assess whether the required functionality is there.
• Use a try before you buy approach. Don’t just say your software is easy to use. If your software product is as easy to use as you say it is, then why not let people see that for themselves? Offer them the option to download of a copy of your software and try it before asking them to pay for it.
• Specify supported OS-es and licensing type. A list of supported operating systems is as necessary when selling software online as when selling it in a box in a traditional store. It has to be put in an easy to spot place for potential customers to find out at a glance whether the product will work on their computers or not. Adding other system requirements would be a good idea, too. Do specify the type of licensing for your software product (i.e. freeware, shareware etc).
• Include a help file and support details. Your software product has to have some documentation explaining users how to use it, be it in form of a help file or an online manual either included with the product or that can be downloaded separately. People also need to know where to reach you in case they need support, so do not forget to include such details (an e-mail address, and maybe a phone number, too).

Letting people see the product (by screen shots) and try it before they buy, providing help files with your software and support when necessary, properly testing it with real users to make sure it is easy to use are the things that you should have on your to-do list if you plan on selling software online and be successful at it.

Cross selling involves five fundamentals:
• You have to know your products very well.
• You have to know your clients. To get the best results identify which customers are your best target.
• Ask questions and listen for clues.
• Pay attention to clients needs and only suggest relevant products.
• Suggest, don’t impose. These way clients will feel comfortable and more likely to accept your offer.

Most of the time, cross selling is a natural process, involving a simple operation: telling customers about your products. In software marketing, the publisher needs to establish which software product can be correlated with another one and be sold together as a package deal. Both the selection and the price can be based on several customer and product criteria, which should be set up before deciding on using the cross selling technique. These bundles may be added to the online shopping cart or advertised as a special software promotion on the site.

Successful cross selling can be achieved by applying several rules:
• Right timing. Don’t push sales if it seems the client doesn’t have the financial resources at that moment. Try to find out what the clients budget is and make your offer accordingly.
• Relevance. Suggesting too many software products unrelated to the original one may overwhelm the client and lead to failure.
• Post recommendations on the site. Professionals, experts or other customers may post their opinion and their recommendations on the site. It can show up as a list of related items bought by other customers that purchased the same product.
• Place cross selling items throughout your site, where they can help shoppers learn about your software products and business. Try mixing and matching different items to see which combinations work best.
• Offer a range of prices: low cost items may be considered impulse buys, but the clients may also purchase higher priced items that fit their needs.
The most important aspect in cross selling is customer satisfaction with the first software product they purchase, alongside with price and how well additional products fit their needs. In order for cross selling to work, the focus should be on the customer, not on pushing a certain software program. Before talking about additional products or services, the customer’s problems must be solved. Also, the customer needs to know how useful is the product you’re trying to sell in the first place.

What’s the most important downside of cross selling? Annoying clients to the point they leave without buying anything. This occurs if you continue to sell after the customer says he’s not interesting or when you’re pushing a product that’s not useful to the customer. In the end, combining customer service and cross selling will lead to increased online software sales.

Selling software online is not an easy task. How do you make the client truly understand your product and trust it and your company enough to pay the price? Like it or not, it’s very similar to selling face to face: the first impression may be decisive for the client’s future actions. Online, the website is your face.

It has to be comprehensible and easy to use. Here are a few tips on how your website should be to sell software better:
• It has to look professional and attractive at the same time

You don’t have to show off your web designer skills. Too many colours, graphics, flash animations or drop-down boxes can only tire the visitors and make them leave faster. Fewer graphic will also make the site load faster. At the same time, it shouldn’t be dull, so it needs to be somewhere in the middle.
• Make sure your message comes across loud and clear.
In order to sell more software, information about software products must be easy to find, easy to follow and the same goes for the order process. Since most information is in the text, make it easy to read. Some coloured backgrounds make the text difficult to read, like purples, orange and reds. On the other hand, dark backgrounds may have a depressing effect on the visitor’s mood. The text colour is very important. Keep in mind that different browsers show colours differently, so don’t go crazy with it. It’s better to use Plain fonts, like Arial, Times New Roman, Verdana and Courier, because they’re easier to read. Fancier fonts may be used for headlines, but not full text. Remember though that sans serif fonts are easier to read on screen.
• Easy navigation is law.
Make sure there’s a link to the homepage at the top left of every page, except the homepage itself. Be careful not to have dead end from which the visitor can’t find their way back to where they came from. Place the most important links in the top part of each page. Clearly mark read and unread links, preferably using standard colours.
• Base the site’s hierarchy on your customers needs.
Don’t make them search the entire site before they find information about products, prices and payment methods.
• Don’t make pages too long.
A web shouldn’t be more than 23 normal pages lengths, as no one likes an endless scrolling. If you have information for more than that, divide it into several pages with short information clips on the main index page leading to the second page.
• Check all the links on your website to make sure they lead to a page.
Tags from the navigation menu must be representative for what that page is about.
• Serve friendly error messages.
Don’t let the visitors see a page with 404 not found written on it. Put your creativity to good use. Error messages may include navigation to documents that do exist, a search box or a contact email address.
• Have a privacy statement and testimonials.
Potential clients must feel confident dealing with you. Having a separate page to express your policy towards their email addresses, how you accept orders and gather information, who has access to information and how you use that information will help you sell more software. Also make a separate page for comments from satisfied customers. Offer to include links to the customers websites in return for using their comments.
• Contact information or a link to it should be on every page.
If customers need additional information about the product, contact information like a phone number and an email address should be easy to find on the website. Let people know the hours and days of operation and the time needed to answer their requests. Give a contact name; it makes people have more faith that someone will actually read their message.
• Set up a frequently-asked-questions (FAQ) page.
Base it on real questions your customers had in the past.

A software should have strength anti virus application, and security system, this is to avoid any destruction inside the system itself, its the same like having an anti virus protection for some symptoms such as herpes symptoms. Viruses both in symptoms and computer required serious threats and early detection and prevention before spreading widely.

A platform is located on your computer or local area network, which can be deployed as a Web application that is delivered to users around the world using a web server that connects via the Internet. Using a web browser as a client today is finding more and more accepted and used in many applications and products outside the platform to provide a better GUI. This led to the popularity of web applications. It is very important to understand delivery systems on the Internet to find the suitability of converting a desktop application in a Web application. Applications integration optimization techniques search engine became more popular with companies that are oriented marketing or sales, while a unit production may be less attractive to convert the existing application into a Web application.

Some few points that come to light over a desktop application and web applications.
Accessibility: a desktop application is available only on a local computer, while a Web application is available around the world.

Maintenance and updates: web applications that require little or no maintenance and are installed only once on the web server, while desktop applications should be made individually on each computer. Updates / compatibility issues with other are mostly by administrators of the hosting company as opposed to desktop applications. The maintenance of a web application is important paramount as the company puts all its eggs in one basket, uptime is not only necessary but essential to the implementation.

Safety: Line of work has its own set of risks such as hacking and viruses. The risk is higher compared to a desktop as a dysfunction office in May result in partial data loss. The crash of a web server may be having consequences beyond the control of a company.
Cost: Run a Web application includes recurring costs of web space and bandwidth usage, while the use Office is charged at once and has been known for less a period of time.
Connectivity: the reliability of Web applications is based on connectivity but you can use from anywhere in the world, rates of connectivity and adjusting the bandwidth may make it unnecessary in some areas. The lack of Internet access businesses in the end or side of the web server may cause unwarranted delays. Critical applications may suffer as a result of these failures.

The Web application over slow compared with the performance of desktop applications due to slower data transfer via the Internet. The speed of connectivity and bandwidth usage can be important factors.

The popularity of web applications is only due to accessibility, despite its limited functionality.
