Perceptual Ad Blocker blocks ads by graphic elements, not by code

A few guys from Princeton and Stanford universities have worked together and create Perceptual Ad Blocker, a different piece of adblocking software, that detects ads by the graphical elements, the content dimensions and the sponsored words. The software does not hide the ads completely, but covers them and displays the “This is an ad” text.

As you may know, the classical adblocking software analyzes the source code of pages to identify the ads, while Perceptual Ad blocker does things in a different way. It has been initially released to block the annoying Facebook Ads, after the website has started to integrate the ads in the content better and better, and the classical ad blockers could not block them.

Another good thing about Perceptual Adblock is that it is not discovered by the websites, being an ideal solution for that kind of websites that do not offer the content if you do not whitelist them in your adblocker. It has been tested on 50 websites that usually detect adblockers, but it has been invisible.

For now, Perceptual Ad Blocker is just a proof of concept, available only for Google Chrome, as an extension. For more information, see this thread on the MMO-Champion forum.

4 things to do to keep your business safe from WannaCry-like internet infections

The WannaCry cyber attack has created a lot of panic, due to the fact that it has infected computers from over 120 countries, being the largest ransomware infection in history.

As I work for an outsourcing IT company, I have noticed that people got very worried that such an attack can destroy their businesses and started to buy backup solutions and to invest more in computer security.

In this article I will give you 4 tips that will save your business from a future WannaCry-like computer virus infections.

Backup the fileserver, user data and the operating system:

The easiest way to backup user files is to create a special folder for each user on the fileserver and to back it up constatly, along with the entire server backup. This way, everything placed by the users in their folders are backed up.

From my experience, it is better to backup a single computer or server from the network, instead of backing up files from all the computers on the network. Without a good network infrastructure, this would make the network unresponsive.

In addition to this, another good habbit is to create full system backups of all the computers on the network, making an bootable image of the fresh operating system, with all the drivers installed, all the license keys added and drivers installed. This way, the reinstall process gets done very quick.

Another good habbit is to have a 2 TB or bigger external hard drive and to use it to perform offline backups for the server, when the automatic one fails.

Antivirus solutions and anti-ransomware software:

While there are a lot of free decent antivirus software, this is not enough in the business environment. We recommend that you buy an endpoint security antivirus, in order to benefit from extra security modules such as email scanning, certificate scanning, port blocking et cetera.

Despite the fact that we like using ESET EndPoint Security, Kaspersky, Bitdefender and Symantec have good security solutions as well.

Added to this, we recommend using an anti-ransomware software, such as CryptoGuard or RansomFree Cyberreason, which are two pieces of free software that close the encryption process, when the ransomware starts it.

For extra security, or for the paranoid users, we recommend Zemana, a secundary antimalware software that can run along other antivirus software, famous for its anti-ransomware protection.

Keep your operating systems up to date:

A good security practice is to use supported operating systems, like Windows 7, Windows 8.1 or Windows 10. While Windows Updates may make the system a bit unresponsive, it is a necessary evil, let’s say.

A good practice is to update the operating system daily, at the end of the working hours.

User training:

Yet another important thing to do is to train the users how to spot malicious emails, ignore the attachments and delete them. In most of the cases, the strange emails are either infected or phishing emails.

I know it’s difficult to keep the network and computers safe, but it’s even more difficult to recover the encrypted data.

How to delete your Instagram account

No matter what the reason would be that make you take the decision to give up on your Instagram account (AndroidiOSWindows Phone), we will ofer you two easy solutions for that: temporarily deactivation or permanent deactivation of the account. As the option name states, the first option will allow you to temporarily deactivate your account without losing any data, pictures etc. and all the information from the account will be hidden from other users until you reactivate the account. On the other hand, the second option is a little bit more of a drastic measure that wipes the account permanently including pictures, information or any data the account might held.

Both procedures can be either carried out from the app itself, or from a browser on a PC, laptop, tablet or mobile phone.
