This article will explain how one can remove a "managed" Google Chrome extension. Notice that recently we are seeing a rise in adware infections, in many cases such PUP (potentially unwanted programs) installs on users Internet browsers disguised as legitimate browser extensions. Most commonly adware comes bundled with free software downloaded from the Internet and it's installation is a consequence of not paying close attention to the installation steps.

Internet access is blocked due to malware infection, how to eliminate it?
This tutorial will show you how to regain control of your Internet access if it's blocked by malware. Some variants of malware alters Internet browsers settings by adding a Proxy Server, in such case you won't be able to visit any websites and thus you won't be able to download required software to eliminate security infections. Other types of malware changes computer's DNS settings or adds various entries to your operating system's HOSTS file. By changing these settings computer viruses can cause redirect issues or completely block Internet connection. If you can't access Internet and you suspect that this may be caused by some virus infection check these settings and make sure that everything is in place.

Meet the participants - Fake antiviruses
After spending some time when searching for various fake antivirus samples I selected 14 participants. All of them are fake antiviruses that tries to scare user into buying full versions by displaying fake warnings and errors. Some of them are old versions, some are recent. Before starting a test I scanned all samples with AVG Antivirus free edition and one of them is even not detected by this antivirus with very recent updates.
