CyberCapture: Protection against zero-second attacks

This week we released a new version of our core PC antivirus product, which we refer to as the Avast Antivirus Nitro Update. The update’s name is Nitro, because it is filled with innovative, new ways to increase speed and increase protection. One of the new ways we are increasing protection is with a cool new proprietary technology called CyberCapture. CyberCapture dramatically raises the bar when it comes to protection against zero-second attacks.

Retefe banking Trojan targets UK banking customers

The Retefe banking Trojan has been around for some time, targeting Sweden, Switzerland and Japan, as previously reported by Paloalto Research.

We recently noticed Retefe campaigns targeting UK banking customers. Using fake certificates, the Trojan is designed to trick victims into giving up their login credentials and other sensitive information.

At first, the victim receives a document with an embedded malicious JavaScript file per email. The document contains a very small image with a note asking the user to double click on it to view it better. After double clicking, the malicious embedded JavaScript is executed. The document has a notice message in German, however, the Trojan banker is targeting users in UK.

What is Nitro? Our newest, high-speed version of Avast Antivirus

Avast Antivirus Nitro Update is lightweight, delivers improved performance and includes our latest CyberCapture technology with zero-second threat detection against unrecognized files.

If you own a PC, you know you hate it when your antivirus software slows you down, so we developed our latest release to be strong and lightweight, with lower system impact to keep your PC running smoothly and protect you from the never-ending attacks we all experience.

So how do we keep the Nitro Update to Avast so lightweight? One way is we use new technology that utilizes the cloud to identify and analyze threats, which means Avast Antivirus Nitro Update is light enough that it doesn’t eat up your system’s resources. Our security software is smaller in size and designed to improve speed, boot time, download time, and system performance in Windows 10.

wrong tool for the jobUsing the right tool makes all the difference.

Everyone knows that you need the right tool to do a job. When you cut down a tree, you don’t use a butter knife, you use a chainsaw. It you want to win a Formula 1 race, you don’t drive a riding lawnmower.

The same rule applies to your PC’s security.

You can’t go up against today’s online threats without the best protection. That’s why Windows 10 users need to install strong antivirus software to run in parallel with Microsoft’s pre-installed antivirus, Defender.

Out of storage? Photo Space creates space on your iPhone

New Photo Space app fits 7GB worth of photos into 1GB of space

How many times have you seen a message like this?

If you are like the thousands of iPhone users around the world, then you see that message all too frequently. Of course, it always pops up just as you want to take a picture. 😬

People told us that to get more space they resort to uninstalling apps and deleting photos. A few get storage from iCloud, but they complain that they have no control and it gets expensive to pay for more space.

None of those are very good solutions. So we came up with something better.

Avast Photo Space

Photo Space is a free app that takes your high-quality photos and optimizes them to reduce the amount of storage they occupy. That means that you get 7 times more space for your photos and apps.
