Viruses and the Importance of Correct Protection Against Them | Antivirus Software

Earlier, we told you that building the right virus protection is essential for every site. Search engine robots constantly monitor the presence of viruses on sites and do everything to ensure that such a site does not appear in the search results. One of the most obvious actions here is to prevent users from going to such a site. You yourself can imagine what the harm will be for the site from the restrictions associated with the spread of viruses.

Since the harm itself from viruses is obvious, we will tell you why viruses appear on sites. Moreover, we will cover the topic of prevention and protection against viruses. This information will be the best option for you when working with a large number of sites. Before we start the story, we recommend that you check the Security tab in Yandex.Webmaster. It is in it that information is collected about which viruses are present on your site at the moment.

The main reasons for the infection of sites with viruses

To understand exactly how to deal with viruses on your site, you should, first of all, know where they come from. Practice shows that a virus can "pick up" many resources, and often the main reason for this lies in the fact that their owners did not pay too much attention to security issues.

Let's consider only the main reasons for the spread of threats, which can not only endanger your site but also negate all the costs of its active promotion.

Outdated antiviruses. This is one of the most common causes of computer system infections. And this is not just about websites. It often happens that specialists work at the computer who do not pay due attention to security. Many people think that having installed an antivirus once, you don't have to worry about updating it. However, many antiviruses, and especially those distributed free of charge, require constant updating, including manual ones. Therefore, when working with the site, you need to take care of how to properly protect your computer and constantly make sure that it has up-to-date and fresh versions of antivirus software programs with complete databases of new threats.

Outdated browser. In some cases, the administrator can infect the site even when using outdated versions of browsers. The fact is that with the development of browsers, their internal protection against threats also grows. This means that the earlier the browser was released and the more time it was without updating, the more likely it will be successfully attacked.

Simple password. It often happens that low-security passwords are used to manage critical site controls. This is especially true when using content management systems. Often, attackers quickly brute-force passwords and at the same time gain full access to the admin panel of your site.

Outdated CMS. The content management system is what is often attacked in the first place. Many CMS that was created a long time ago and do not have adequate anti-virus protection can be attacked by cybercriminals. This allows you to permanently disrupt the performance of your site, as well as lead to the fact that it will be infected with a virus, which means it will go to the list of sanctions from search engines. For many old content management systems, there is a fairly detailed list of vulnerabilities that cyber criminals still successfully use today.

Trojans. Many antiviruses knowingly warn computer owners not to install programs from unknown and unreliable sources. However, practice shows that webmasters continue to step on the old rake and at the same time install dubious programs. A side effect of this attitude towards your site is the introduction of various Trojans on it, which may pose a threat to your visitors in the future. As practice shows, Trojans turn out to be malicious both from the point of view of harming users and indexing sites.

How to protect your website from viruses?

So, the main list of threats has been determined and now you should pay special attention to how exactly your site is protected from viruses. Most of the recommendations below can be drawn directly from the threats themselves.

Here are the simple facts that you need to pay your closest attention to:

Always try to check what programs are installed on your computer. If the system warns that the program comes from an unreliable source, you shouldn't use it. Install only those programs that have been tested and have security certificates.

Change passwords regularly and do not save them in the browser of your personal computer. It is best if the password is changed every 3 months and at least.

Always make sure you have the correct antivirus software on your computer that is updated to the latest versions. Please note that it is best to use paid antiviruses, as free versions of programs may be late with updating the databases of threats that are growing every day. If you want to save money, then take care of the availability of a paid advanced antivirus at least on the computers of those specialists who are directly related to the administration of your site.

Carefully approach the choice of the management system for your site. Especially it is worth paying attention to security for those who use old versions of CMS, which have a huge number of elements with a low level of security. Never install new, untested modules on your CMS. Please note that in some cases unique CMSs are used, which are developed by a separate company. In this case, you will need to ensure the maximum level of security. It can be simple - you just need to read the list of security recommendations.

The programmer must check the source code on your site. It is best if the programmer who originally wrote it will work with the site code. Such a specialist will understand that various kinds of changes have appeared in the code. This could be a sign that malicious software is present on the site. The programmer will be able to quickly take action to eliminate it completely.

Check your site folders regularly. You must remember exactly what files they contain. It often happens that malicious software is installed even without the knowledge of the site administrator. In this case, an extraneous element may also appear in the site folders. If you find any unfamiliar item in a folder, you should consider this carefully and consult with your person in charge of security.

Always try to use only up-to-date browser versions. Otherwise, you will get a high vulnerability of your site to a large number of threats. Please note that most browsers are automatically updated. Take this opportunity to get the maximum protective effect.

Main conclusions

As can be understood from all that has been said above, there are no secondary aspects in the protection of a resource that could be omitted or treated with insufficient attention. To guarantee a high level of security for your resource, you will need to approach security issues fully. It is best to introduce an official set of safety rules in the company that operates the site, which all employees must read and follow. The most important thing in this regard is to carefully approach compliance with all safety requirements without exception - it is simple, but it can protect you from many problems.
