Avira Antivirus Pro - Review 2020 - PCMag IndiaAvira Antivirus Pro - Review 2020 - PCMag IndiaPosted: 11 Jun 2020 12:00 AM PDTEvery computer needs antivirus protection, and one way companies can support that aim is to provide free antivirus to the masses. But these companies can't survive unless some users shell out their hard-earned cash for paid antivirus utilities. Piling on pro-only tools and components is one way companies encourage upgrading to a paid antivirus. Avira Antivirus Pro adds several components not available to users of Avira Free Security, but they don't really add much value. The biggest reason to pay for it is if you want to use Avira in a commercial setting, which isn't allowed with the free version.Avira's pricing is undeniably on the high side, with a list price of $59.88 per year for one license, $71.88 for three, and $95.88 for five. Admittedly, it seems to be perpetually on sale; just now, the one-license price is discounted to $44.99. That…

You'd come across terms like malware vs virus when researching for website security. Both terms are often used interchangeably but the truth is they are slightly different from each other. In this article, you'll learn the difference between the two. We'll learn about the different types of malware that exist and the steps you can take to secure your website against them.


If you suspect that your website contains malware, clean it immediately. Install this WordPress malware removal plugin, it'll scan your site and clean it under 60 seconds. Moreover, the plugin will help you harden your website against future hack attacks.

What Is the Difference Between Malware and Virus?

Malware is an umbrella term that refers to any malicious software that is made with the motive of causing damage to a website or stealing the resources of a website.

There are different types of malware. A virus is a specific type of malware. It is a contagious piece of code that can be injected into files and folders of a website. A virus functions like a parasite. It can replicate itself and spread into other files and folders of your website.

But why are viruses and malware so commonly confused?

Malware found on a WordPress website

To answer that we have to look back to the 1980s.

The first malicious software appeared in the 80s. It was a program that infected computer systems. The term 'computer virus' was used to describe it.

We have come a long way since the 80s. Now there are different types of malicious software infecting systems. Besides computer viruses, there are worms, trojans, adware, etc.

The term 'malware' was coined to include all types of malicious software. But since the term 'virus' was already ingrained in the collective mindset, both terms have come to be often used interchangeably.

It's important to note that there is malware that infects websites and there is malware that infects devices such as computers and smartphones.

Whether it's a website malware and computer malware, the motive is to cause damage or utilize the resources of the host.

So now we know that there are different kinds of malware. The virus is just one type of malware. Let's look at the other types of malware –

What Are the Different Types of Malware?

As we mentioned, malware is an umbrella term used for many different types of malicious programs. Let's look at the 6 most common types of malware found that could be infecting your website. Those are:

    1. Virus
    2. Worms
    3. Trojan
    4. Ransomware
    5. Adware & Spyware
    6. Scareware

1. Virus

A virus is a piece of malicious code that can be injected into a file or a folder. It functions like a parasite. It can replicate itself and spread to other files and folders of your website.

2. Worms

This is a malware designed to destroy a system. It looks for vulnerabilities, exploits it and then moves to a different host system. In a shared hosting environment, it can move through the server destroying one website after another.

3. Trojan

Trojan is an application containing malicious codes. The application may function in a non-malicious way but its true intention will be hidden until it is activated.

Take for instance, a pirated plugin that has a Trojan hidden inside. When you install and activate the plugin on your website, the malicious code is also activated. Trojans are often used to plant a backdoor using which hackers can access your website without your knowledge.

As you may have guessed, the name Trojan comes from the Trojan Horse. Like the Trojan Horse, the Trojan malware deceives and tricks users into willingly running it.

Many malware detection scanners are unable to detect Trojans because they are often mistaken as non-malicious. Only WordPress security plugins like MalCare that are designed to identify such malware can find and alert users about it.

4. Ransomware

The most notorious malware on our list is ransomware. It can lock your website completely, preventing any site users from accessing it. Hackers can then leave a message for the site owner demanding a ransom usually in bitcoins or other types of cryptocurrency that can't be traced.

5. Adware

Adware, as the name suggests, is malicious advertisements. It appears on websites without the knowledge of the site owners. The motive is to generate revenue off the back of your website's popularity.

Adwares can appear as pop-ups or they can also appear in the header of the infected site.

6. Scareware

As the name suggests, the motive of scareware is to scare the user into taking action. Most of us have seen scareware. It appears like a popup and aggressively alerts you that your computer system or smartphone is hacked and need to be cleaned immediately. The main intention is to push the user to purchase an anti-malware product. In this way, hackers try to use your website to sell products and make a quick buck.

With that, we have come to the end of the types of common malware.

When looking for website security tools, you may across antivirus and antimalware tools. It's natural to wonder what are the differences between antivirus and antimalware. We answer that question in the next section.

What Is The Difference Between Anti-Virus & Anti-Malware?

Anti-virus and anti-malware are essentially the same tools. There is no distinction between the two.

It may cross your mind that anti-virus tools can only clean viruses and no other type of malware but that's not true. Security software companies use the terms anti-virus and anti-malware interchangeably. Therefore, anti-virus and anti-malware tools are essentially the same things. They can remove all types of malware from your WordPress site.

How to Use Anti-Malware To Protect Your Website From Malware & Virus?

There are tons of anti-malware software to choose from but not all are effective.

We spoke about trojans in the previous section. Trojans are good at disguising themselves which is why malware scanners fail to detect it.

Our anti-virus software, MalCare, is designed to find hidden malware. You can start by scanning WordPress database for malware.

    • When other scanners only look for known malware, MalCare goes one step ahead and analyses the behavior of code to figure out if it is malicious or not.
    • Not just that MalCare is designed to scan every file, folder as well as the database to find malware on your website.
    • When malware is found on your website, MalCare cleans it under seconds to prevent any kind of escalation.

    • Moreover, MalCare is a complete security suite. Using the software you can set a firewall and take site hardening and other malware protection measures.

To use MalCare, you'll need to take the following steps –

Step 1: Sign up with MalCare.

Step 2: Then install the plugin to your website and that's it.

The first thing that MalCare will do is scan your site completely. If it finds any malware, it'll alert you immediately. And you can clean your website using the plugin.

Final Thoughts

If you are running a website, there is a real chance that the site can become a target for malware attacks.

Many site owners make the mistake of thinking that their site is small to be a target. Truth is, hacker tends to target small websites because small sites are callous about their security. Big or small – all websites need to take measures to ensure that their site is safe from hackers.

If they gain access to your site, hackers can use it to carry out malicious activities like attacking other websites, storing files, sending spam emails, etc. Just as you protect your computer from cybercriminals, you'd need to protect your website from hackers.

WordPress sites hit by malvertising - Naked Security

Posted: 07 Nov 2019 12:00 AM PST

An old piece of malware is storming the WordPress community, enabling its perpetrators to take control of sites and inject code of their choosing.

According to WordPress security company Wordfence, which published a detailed white paper on the malware earlier this week, WP-VCD isn't a new piece of malware. It dates back to February 2017, but it has recently become even more successful. The company says that it has topped their list of WordPress malware infections since August this year. New features have been added to the malware, but its core functions have remained the same.

The malware spreads through pirated versions of WordPress themes and plugins that the attackers distribute through a network of rogue sites.

If administrators looking for free WordPress functionality download these assets and use them in their own WordPress sites, then they've essentially infected their own servers.

This is an ingenious attack vector because the criminals distributing the plugins don't have to worry about finding new exploits in WordPress code or hacking legitimate extensions. Instead, as Wordfence explains, the crooks are exploiting human greed:

The campaign's distribution doesn't rely on exploiting new software vulnerabilities or cracking login credentials, it simply relies on WordPress site owners seeking free access to paid software.

Once it has infected one site, the malware then installs a backdoor for its operators and communicates with its command-and-control (C2) server before spreading to others hosted in the same infrastructure. Finally, it removes the malicious code in the installed plugin to cover its tracks.

The backdoor lets the attackers update the site with new malicious code, which makes money for its criminal peddlers in two ways. First, it uses search engine poisoning techniques to manipulate search results and lure unsuspecting users to malicious sites.

Second, it pushes malicious adverts (malvertising) into the pages that victims visit, enabling the attackers either to inject rogue JavaScript into their browsers, or to redirect them to other websites.

Why has the WP-VCD WordPress malware been so effective? Wordfence explains that its attackers can use infected sites to propagate their malware:

Malvertising code is deployed to generate ad revenue from infected sites, and if the influx of new WP-VCD infections slows down, the attacker can deploy [search poisoning] code to drive up search engine traffic to their distribution sites and attract new victims.

The WP-VCD malware is tricky to clean because it injects malicious code into other files on the system, and keeps an eye on infected files to reinfect them automatically if the admin tries to clean them up.

What to do?

Naked Security's plugin advice for WordPress administrators is:

  • Minimise the number of plugins you have. Always remove plugins if you aren't using them any more. Keep your attack surface area as small as you can.
  • Keep your plugins up to date. Blogging software such as WordPress can keep itself updated, but you need to keep track of the plugins yourself.
  • Get rid of plugins that aren't getting any more love and attention from their developers. Don't stick with 'abandonware' plugins, because they'll never get security fixes.
  • Learn what to look for in your logs. Know where to go to look for a record of what your web server, your blogging software and your plugins have been up to. Attacks often stand out clearly and early if you know what to look for, and if you do so regularly.

Oh, and don't steal software.

Technically, there's no reason why pirating software should be more dangerous than acquiring it lawfully – an exact copy is, after all, an exact copy. But the shady nature of rogue software download sites means that the only thing you can be sure of is that you're dealing with crooks.
