12 angry minions

avast! GrimeFighter is one of the most popular new products among AVAST users.

However, many of you still don’t know the benefits of it or what avast! GrimeFighter does. Therefore we have prepared a series of articles with a “movie theme” to show you the functionality of our Grime-fighting minions! The first one, Learn everything you always wanted to know about avast! GrimeFighter, but were afraid to ask!, gave you an overview of product functionality. Now let’s dig a bit deeper into the subject.

12 Angry minions.

The Grime Fighter crew work together towards one goal: Cleaning and optimizing your PCs performance. They have no mercy for temporary and unwanted files and apps, including ‘bloatware’ and ‘crapware’. This is a very complicated task, therefore our 12 Angry minions analyze each element in depth before deleting anything that is actually important to you. This influences the time of the cleaning process (it takes up to 4 hours depending on the initial state of your PC), but also ensures results: A more efficient and faster machine. Although our minions make it look easy and entertaining, cleaning Grime so thoroughly is a complex task!
avast! GrimeFighter optimizes your PC better than other products.

For the same reason each minion has it’s specialization and focus on different tasks:

OFFICER PETE is head of the GrimeFighter team.

KOBAYASHI sneaks up on malware to eliminate it from your PC.

NIKITA specializes in cleaning and maintaining your web browser.

DALE JUMPSHOT JR. focuses on removing crapware and bloatware to speed up Windows load time.

BEEF strengthens the security of your applications.

TORQUE tuns up and optimizes Windows services and settings.

SIR JEFFREY investigates and analyzes your PC hardware components.

MARIO analyzes your network connection for security and speed.

DR. LIZA analyzes and classifies all of the stuff on your hard drive.

ZILCH takes out the trash on your PC to free up your drive space.

MAXIMUS analyzes and researches the newest hacking trends the instant they emerge, and  last but not least HOLMES focuses on your privacy settings.

The avast! Minions perform deep analysis, by booting your PC into Linux to identify Grime and clean every corner of your PC. Some forms of Grime are hard to remove when Windows is running, but can’t hide when we sedate your computer. Unwanted files and apps go by many names, including ‘bloatware’, ‘crapware’, and sometimes even half-jokingly using the name ‘virus.’ We define all of these as ‘Grime.’ The image below visualize Minions in action.

To summarize: Computer users can download avast! GrimeFighter’s scan tool to have their PC examined for free. It finds anything that slows the PC. If users then want to clean their PCs, they may buy their own GrimeFighter license, to purge Grime from the PC. GrimeFighter’s minions do all the maintenance work… while you surf the web or sip a cup a tea. For more information, please visit our website.

Nice apps get bad makeover after spammers buy them

Spammers buy Chrome extensions and turn them into adware ~PC World

This is one “before and after” picture that we didn’t want to see. Someone contacted the original developers of Chrome extensions Add to Feedly and Tweet This Page with an offer to purchase. Thinking it was a good opportunity for a company with more time and money to further develop what they started, both developers sold perfectly nice apps. It wasn’t until the next automatic update that the true transformation was revealed.

Even though users didn’t know about the sale of the extensions, angry reviews indicated that a change had been made. The app was accused of spamming because it had silently updated the extensions to inject ads and affiliate links. Amit Agarwal, Add to Feedly‘s original author told PC World, “These aren’t regular banner ads that you see on webpages, these are invisible ads that work the background and replace links on every website that you visit into affiliate links. In simple English, if the extension is activated in Chrome, it will inject adware into all webpages.”

Over the weekend, the two extensions were removed from the Chrome Web Store.

How to remove bad extensions and toolbars from your computer

“Both of these add-ons are categorized as “very bad” in the avast! Browser Cleanup database,” said Thomas Salomon, head of AVAST Software’s Browser Cleanup development.  “Browser Cleanup will remove them without any trace. This means they’ll be removed the same way as any other bad add-on/toolbar.”

Open the AVAST user interface to access Browser Cleanup

avast! Browser Cleanup lists all poorly rated add-ons, extensions, and toolbars for the 3 major internet browsers, Microsoft Internet Explorer, Mozilla Firefox, and Google Chrome, and allows you to disable or remove them. It works by scanning the browser environment, then displays a list of any bad toolbars you may have, and asks if you want the offending toolbar removed. If you authorize it to do so, then Browser Cleanup will remove them.

There are more than 7,500,000 different browser extensions for the three main browsers. AVAST currently receives 1 million requests every day to remove browser toolbars. Read more about annoying toolbars from this blog post by Thomas Salomon.

Comparison of Adware in Windows and OS X: Linkular and Genieo

By definition, Adware is a program bundle which renders advertisements in order to generate revenue for its author. In a more strict sense, e.g. for security solutions, it means an application/installer whose nature lies somewhere between a potentially unwanted application and proper malware, like Trojans or Spyware. It might use more or less aggressive methods, starting with tricks and ending with fraud, to achieve its goals to benefit its distributor, while staying as innocent as possible on first sight. We blogged about an adware downloader a year ago.

Now we focus on two selected adware examples: The first is a Windows installer called Linkular and the second is a well-known application called Genieo (with a focus on its OS X version.) Being in the wild for a few months, the detection within AV products reached only partial coverage in both cases, with very similar numbers on VirusTotal (~10-20 %, see Sources below). However, the OS X adware Genieo is additionally flagged by OS X-specific security solutions. Considering maliciousness, the Windows adware is far more dangerous and invasive than the OS X one and also more than other Windows Adware examples we usually see. Here’s the comparison:

Make money fast via torrents

Several months ago I wrote a blog post about an adware downloader which after execution downloaded a few adware programs and installed them on the computer, giving no chance for the user to skip or bypass their installation. This time, we will analyze an application, which installs similar types of adware programs on user computers.

We received a file which appeared to be a crack of Pinnacle Studio HD Ultimate. After displaying the initial splash screen, it offers the user to install Pinnacle Pixie Activation 500. After confirmation, the crack is installed, but in addition to the crack, other programs and toolbars unexpectedly appeared on the compromised computer. Pinnacle was not the only target of this kind of attack. Cracks for programs like Sims, Nero, Rosetta Stone, and Pro Evolution Soccer 2013 were also used in distribution.

Fake “Bad Piggies” infect Google Chrome users

Bad Piggies, the spin-off game to Rovio’s wildly popular Angry Birds, hit the online stores last week, and following in its sizable wake were fake versions designed to install an aggressive adware program into Chrome browsers. Reportedly, over 83,000 Google Chrome users have been infected.

Cybercrooks found a niche because Bad Piggies is only available for Android devices on Google Play (free) or Apple devices ($0.99 for iPhone and $2.99 for iPad) on iTunes. Free versions of Bad Piggies that claimed to be from the creators of Angry Birds appeared on the Chrome web store shortly after the release. The top 3 listed are called Bad Piggies, but they are from different companies; padeba, gametc.com, and the HD version from HitsGames. They have over 13,000 downloads.

Reviews of the games reveal the anger and disappointment of Rovio fans. Read more…
