WHERE DO VIRUSES COME FROM ON THE SITE ?

Imagine that you are a happy owner of your own website, which is developing and gaining popularity every day. Suddenly, all of a sudden, at the next entrance, the antivirus program began to swear that the site was blocked by Vikrus! Or did the users of the site tell you about the presence of viruses by contacting Feedback? Or did interactive scripts stop working on the site? What does this mean?

All this suggests that the resource is infected with viruses, i.e. alien malicious code. How did he get there, who is to blame, and how to remove it, as well as what needs to be done to avoid such problems in the future? All these questions arise from many more inexperienced owners, and even from experienced ones. We will try to answer them.

WHAT IS A VIRUS LIKE?

Malicious code is encrypted JavaScript-code that is inserted into the code page of the site. When it is executed, an iframe is formed (the ability to include and display images or the contents of one page in another). It is when an inserted iframe is detected that the alarm must be sounded immediately. Such attacks can be carried out on both private and corporate sites. In no case can postpone the treatment of an infected site until later. First of all, the reputation of the site itself suffers. He will lose regular users who were so hard to get involved.

The virus on the site is a big nuisance.

SITE INFECTION MECHANISM

In the overwhelming majority of cases, the site is blocked by a virus that gets to it through the computers from which FTP access was made to it. First, the virus hits exactly on the device itself. There he discovers and copies passwords for access and steals them. Passwords are sent to the computers of hackers, where programs are installed – robots that trust all the “dirty” work. Robot programs perform FTP access using the received passwords, detect root files, download them, add their own malicious code to the end of the code and upload them back, replacing the originals with them.

At the same time, the server cannot determine that at that moment they entered the site from another computer, since the whole procedure looks like a regular login to the user’s site via FTP. The server will think that this owner has come to check how things are going there.

VIRUS REMOVAL

The first step is to prevent re-infection and protect the site from viruses. To do this, you need to urgently change access passwords, check all computers that are running FTP access for viruses. Antiviruses should be powerful with updated databases.

In order to remove the malicious code and protect the site from viruses, simply open the infected file, find the desired site, delete it and save the clean file. In some cases, the file may contain several codes at once. And sometimes the files are damaged so much that it is much easier to delete them and restore everything using backup copies of the files. This will significantly save time than if you will waste time and heal the resource manually.

PREVENTING INFECTIONS IN THE FUTURE

Stepping on a rake once, do not do this in the future. To prevent a situation when the site is blocked by a virus, you must observe the following security rules:

  • It is better not to use the ability to save passwords in FTP clients. Access passwords should be changed regularly.
  • Write them on a piece of paper or copy it onto removable media and hide it in a safe place, but do not let them be in the hands of others even from your personal environment.
  • It is better to minimize the number of devices from which the FTP-access.
  • For FTP access, you should use reliable and modern computers with good antivirus programs. The programs themselves must be licensed, with all the included verification options, with updated databases. Choose an expensive but reliable product with a reputation and positive reviews.

HOW TO USE MULTIPLE DOMAINS FOR ONE SITE?

The situation when it is necessary to promote several domains simultaneously for the same site requires from the owner well-designed technological solutions. It is very easy to break with the effective presentation of your web project in the area of ​​failures and failures.

HOW CAN I FIND OUT ON HOW MANY DOMAINS THE SITE IS LOCATED?

The fact that a functioning site (hangs) simultaneously on several domains is usually recognized in two main ways. Or, bumping into a parallel domain, looking at search engine results for key queries on the main site, it happens that sites with two domains are made so that they both appear on the top lines in the search engines. 

Practicing two sites – This is not the most useful way, mainly because it automatically means duplicate content on both domains, since non-unique pages and texts on the site are bad and are fraught with a downgrade. However, these domains can be applied.

Multiple domains for one site - crossroad in the network

HOW TO USE MULTIPLE DOMAINS

CREATE A RESERVE – SEVERAL DOMAINS ON ONE SITE

Some organizations may fear that their active competitors will acquire domains that use similar names for their services or products – keywords, thereby promoting their own website. This fact can lead to panic purchases of different domain names. The idea is that as long as they directly own all the domains, they reduce the chances of competitors overtaking them in the so-called search results.

Although there is a definite meaning and task in this tactic, for search engine optimization it is in fact useless. And it is not at all obvious that this tactic has any influence on the competitors’ websites. It is difficult to think out all the options for the phrase domain names to buy, and besides, if you buy a lot of them, their support cost can be quite expensive. There is another risk – almost any site can overtake you, using more unique and high-quality content and, accordingly, acquiring more links, no matter what domain it is in and what it is called.

A useful note: if you use this tactic, make sure that all domains will be automatically redirected to the main domain using the redirect number 301.

DOMINANCE IN SEARCH ENGINE RESULTS

By purchasing several similar domains, companies want to get a better place in the search service results. If you have several own sites on the first page in the TOP 10 of the search results, is it possible to get more unique traffic? In theory, yes. However, this tactic has a couple of significant drawbacks.

EXCESS FOR OFFLINE PROJECTS

If your site is located at one specific address, then having a couple of additional sites will not be the most successful idea. This can confuse your visitors. In addition to the above, the popular Google search service is not very relevant to this situation, when one organization has many identical sites, as this does not help ensure good search results. In fact, these actions have a great similarity with spam.

PROBLEMS ARISING FROM NON-UNIQUE CONTENT.

Since you will not be able to use content from your main site, you will have to create new and unique pages and texts. Given the complexity of creating high-grade and unique content, and the time spent on it, we can only sincerely wish good luck in creating useful articles describing another additional site.

HOW TO CALCULATE THE AMOUNT OF TRAFFIC FOR YOUR SITE?

There are very favorable hosting rates for site hosting. But sometimes they are intimidated by traffic restrictions. We will understand how to determine whether the site will fit into the established framework.

BANDWIDTH CALCULATION

A simple calculation can tell a lot of interesting things: 
Required traffic = average number of page views x average page weight x average number of visitors per day x number of days per month x reserve. 
The average number of visitors per day is the total number of visitors per month, you need to divide by 30.

  • The average page weight is the average size of a single page file.
  • The average number of page views is the average number of page views per visitor.
  • Reserve is a safety factor that varies between 1.3-1.8.

We arrange the numbers, and get a rough estimate of the bandwidth that is required for your site.

CALCULATION OF THE BANDWIDTH OF THE SITE FROM WHICH YOU CAN DOWNLOAD A FILE

The calculation is carried out in a similar way, only need to identify additional channels for download. Site bandwidth and downloads are easily calculated using the formula: 
Required traffic = [(Average number of page views x average page weight x average number of visitors per day) + (average number of downloads per day x average file size)] x number of days per month x reserve . 
The average number of visitors per day is the total number of visitors per month should be divided by 30

  • The average page weight is the average size of a single page file.
  • The average number of page views is the average number of page views per visitor.
  • The average file size is the total size of the site files divided by the number.
  • Reserve is a safety factor that varies between 1.3 – 1.8.

EXCESS BANDWIDTH

Now you understand that there is a certain margin of safety, ranging from 30% to 80%, which is used in the calculation of throughput. The reason for this is that the bandwidth reserve is crucial, if necessary to withstand sudden spikes in traffic.

That is, the higher the backup rate, the more stable the server. So, it can cope with an unexpected jump in traffic that can erase all the differences between a successful and unsuccessful advertising campaign site.

For example, your article was on the first page of Google for the search query “iphone” – and the server does not cope with a sharp increase in traffic. That is how a good advertising campaign suddenly ended very badly.

The amount of traffic for the site is quite simple to calculate

HOW TO DETERMINE IF A SITE NEEDS MORE BANDWIDTH?

As a rule, if the site is constantly busy and slow, this is the first sign that a higher bandwidth is required.

The probability that the provider simply does not have enough bandwidth reserve capacity is also not excluded. To solve this problem, it is necessary to increase the bandwidth, or switch to a dedicated server, since there is no need to share the bandwidth of the site with other hosting clients.

In addition, you can use file hosting services, which not only allows you to save an impressive margin of site bandwidth, but also make a profit for downloading your files.

CONCLUSION

When choosing a suitable hosting plan, you should, in addition to the amount of bandwidth, pay particular attention to some details.

The frequency of the processor, the number of databases, RAM – this is just a partial list. In fact, without quality resources on these parameters – unlimited bandwidth loses its meaning.

HOW TO MOVE A SITE FROM ONE HOSTING TO ANOTHER

Sites from one hosting to another can be transferred for various reasons, starting with frequent server shutdowns, the excessive cost of provider services and ending with insufficient technical support and many other uncomfortable features.

The most important thing when transferring a site to another hosting service is to perform a “move” with high quality and as quickly as possible, because when you turn off, there is an outflow of regular visitors, which can be difficult to return. Therefore, it is desirable that the work of the resource is not interrupted at all. Next, we will try to disassemble the standard conditions for transferring a site from one hosting to another, since there are many providers that have special settings of the administration panel, the consideration of which will take more than one page.

The whole procedure of transferring a site from hosting to hosting consists of three main stages, each of which we will discuss in more detail:

  1. Change of addresses of domain names.
  2. Database transfer.
  3. Transfer codes of all pages and scripts.
We transfer the site to another hosting

STEP 1

Step 1 is a procedure for changing the addresses of the site domain names to new ones belonging to the “new” provider. These data can be found in the technical support service, and then entered in the administration panel.

Addresses have something like this: ns1.hoster.ru  and so on, a total of a maximum of four (usually two). Hoster in the address bar is replaced with the name of the new host. So, in most cases, it is enough to specify only two addresses instead of four, sometimes with ip-addresses, so the address will look like this: ns 1. hoster ru . 111.111.11.11 (in the place of “111.111.11.11” there will be real addresses).

After that, you can enter the administration panel and, under the line “Change DNS servers”, “Domain settings” or similar, go directly to changing old addresses to new ones. At the end, be sure to press the save button. As a result, the mail will receive a notification letter, which will indicate the procedure that you followed.

STEP 2

We transfer the site database to another hosting. First you need to copy the existing database – site dump. To do this, in the control panel, find the item “Database” or similar, where the link to the tool that manages the site DBMS will be located. There are a large number of such modules, so in the article we will focus on PHPMyAdmin. In this panel, you need to select the name of the required database to save, the entire list of which is located on the left. Then the window of direct DB management will open. Next you need to select the “Export” link and send everything to the archive and click the “OK” button. After that, the save path on the user’s computer is indicated. Now you need to perform the procedure of importing the old database to the new hosting. This procedure is similar to export, through database management,

STEP 3

We transfer the code of pages and scripts to another hosting. To do this, you need to connect to the old resource via ftp protocol using one of the many programs. Next, copy all files from the www folder to your computer, and then you need to perform the reverse procedure for the new provider.

And the final touch in the “big move” of the site is the indication of new data that will allow you to connect to the database in the source code of the old site. Depending on the CMS site, such information may be in a specific configuration file. Here you need to change the password to the database, address, username and site name.

WHAT IS FILE HOSTING?

The reputation of any site directly depends on availability at any time interval without the slightest expectation from all visitors. Optimally choose a paid file hosting and not fall into the trap provider, then optimally ensure the operation of the Internet site or portal.

Companies that provide the best hosting solutions on the market in enough and you can say in abundance. But for a client who has a need to post his own project on the Internet, the choice can be very difficult. It would seem that it can be easier and simpler than choosing one of the similar ones? It turns out not so simple as it seems. Practically always the same range of services provided provides an opportunity for unscrupulous organizations to work in this market segment. How to distinguish a coupler from a professional? And how not to get into the tricky tariff traps?

The main criterion of reliability and quality – professional paid or free file hosting always offers clients a set of their own developments with a platform combined with the most advanced hosting provider technologies, which include a huge selection of high-speed solutions, high-quality and reliable hardware base (own), unique solutions for achieve a high level of security, flexible options for individual settings. These services will satisfy anyone, the requirements of very demanding users.

File hosting is a special service that provides the client with a place for his files and quick access to them through a special web interface, usually via the http protocol. This service allows you to conveniently distribute or download files. On a special Internet file sharing page (most often on the main one), the user uploads the necessary file to the file sharing server, after the file sharing service gives the user a generated permalink, which he can easily send via e-mail, stir on forums, blogs or send through special systems Im. By clicking on this link, almost any user can download a published file. Some services have useful affiliate programs.

FILE SHARING ALLOWS YOU TO EARN IN TWO WAYS

  • Display contextual advertising. Usually, all file servers introduce an artificial pause with advertising when users request the necessary file. Within 40-120 seconds. The user is shown forced advertising, and only then appears to download the file.
  • Sale of VIP (VIP) or premium (premium) – accounts. For a couple of tens of dollars a year, the user has the opportunity to purchase the right to download files, without advertising and without delays, with increased or full speed as many file sharing services specifically limit the download speed. Owners of a paid account also receive other benefits not available to free users, such as downloading and downloading files from multiple streams.

FREE FILE HOSTING – EARNINGS

The working scheme is about the same: the user, after registering, uploads to the server his own files that have unique URLs. Basically, the user in order to achieve maximum earnings tries to place a direct link to his file on more Internet sites. As a rule, these are special sites, as well as ICQ-mailing, spam and forums. For every hundred downloads of a unique file, paid file hosting pays the user money from two dollars, and, the larger the file, the greater the payment.
