Bitdefender Antivirus Free Edition

Bitdefender Antivirus Free Edition is an antivirus program designed to be fast and to minimize user interaction, while sacrificing nothing of the malware detection and removal capabilities that Bitdefender products are generally known for. Bitdefender is one of the best security software providers. We can trust Bitdefender for their antivirus. Now that they offer a free edition of their antivirus with real-time scanning, it will be a great chance for the users to stay safe from threats.

By default, Bitdefender Antivirus Free Edition scans and cleans your system using only the resources that you, your software or your operating system are not using, thus achieving near-zero impact on your activities. Bitdefender Antivirus Free Edition periodically scans all of your files and handles all security-related decisions for you. This means you will see no pop-ups, no alerts and you will not have to configure any settings whatsoever.


Some features of Bitdefender Antivirus Free Edition are:

  • Real-time Shield – The real time shield is designed to protect access to the entire system. This means that files are scanned as they are accessed or copied. For example, the files you just downloaded from the Internet are scanned immediately.
  • Active Virus Control – Active Virus Control is an innovative proactive detection technology that is able to detect new potential threats for which default protection has not yet been released, very fast and accurately, thus providing an essential protection layer.
  • Intrusion Detection System – This technology makes sure that applications trying to access the Internet or the network are not masked e-threats, by marking them whenever its behavior is suspect and by stopping them if the score becomes high.
  • B-Have – B-HAVE proactively detects unknown threats that other products miss by analyzing applications behavior in a safe environment. If no malicious actions are detected, B-HAVE starts the program normally; otherwise, it will automatically quarantine or delete it.
  • HTTP Scanning – Bitdefender Antivirus Free Edition also scans all the links you are accessing from your browser, checking them for various scams or credit card phishing attempts and blocking them when they are unsafe.

The latest version of Bitdefender includes the following enhancements and changes:

  • Add “Full System Scan” entry in systray menu icon
  • Change “Full Scan” into “Full Sweep” in Auto Scan section
  • Refined Threat Control tab; Per-item actions are now displayed on mouse-over
  • Fixed Logs button issues
  • Fixed Explorer freeze at startup
  • Fixed Multiple entries in Threat Control for the same blocked process
  • Fixed Duplicate entry in Threat Control for an active infection
  • Auto Scan and On-Demand Scan improvements
  • Other fixes and internal improvements

Windows Firewall is a handy tool to control the Internet traffic to and from Windows. Windows Firewall lets the user to allow or disallow programs from accessing the Internet. This dialog box usually comes when we open a program for the first time. Windows Firewall was introduced in Windows XP SP1 and it is still continued in Windows 7 and Windows 8.

Although Windows Firewall is good, it is not easy to operate and configure the Firewall. There are third party tools that can be used to configure Windows Firewall. You can also use Microsoft Management Console in order to configure Firewall related policies or ease you can go to Windows Firewall configuration in the Control Panel.

Download AVG Antivirus 2012 Free Edition [Offline Installer]

Security is the most important factor in today’s online world. It is absolutely important to have a security solution on a computer that can protect the data from viruses and malware. There are free antivirus programs like Avira Antivir, Avast Antivirus Free and AVG Antivirus Free which solve this problem. If you can’t afford a premium security suite, you should always install a free antivirus solution. The free antivirus contains almost all the features that a normal home user needs.

avg antivirus 2012

AVG is the most popular free antivirus. It was not my preferred choice because it had become very heavy on system resources and the detection levels were far less than the other free choices. But AVG free edition has improved a lot in the last two years or so. The new edition of AVG Antivirus Free is AVG Antivirus 2012. Infact AVG has released a 2012 version of all their products.


The most important improvement in the new edition of AVG is the detection rate and the performance. It no longer seems to be a resource hog. The most notable new feature in AVG Antivirus 2012 Free Edition is AVG Accelerator. It optimizes the downloading and browsing speed of the Internet. Another improvement is the addition of AVG Adviser. The adviser will give suggestions to improve the system performance in real time.

By default, if you want to download the new edition, it will download an online installer from the official website. The online installer will then download the rest of the package from the Internet. This is sometimes frustrating to the users who want to have the full offline installer with them. Here I’m giving links to all the installers available, online and offline:

Antivirus Software: Why You Need It?

How many times have you received an email from someone you don’t know asking for your bank details? How often have you logged onto a website and had your computer slow to a crawl or act strangely? In both instances your computer has been subject to an attack. The first attack, while annoying, can be avoided by deleting the email. The second is much more dangerous, you could be already infected and be spreading viruses and malware to your friends and contacts or, have unknowingly given hackers your bank information and contact details.

All to commonplace are stories like these; large companies ruined by botnets made up of compromised home PC’s that have been taken over by hackers. Viruses, trojans, keyloggers–the list of malicious software and the people who have been hurt or affected by it seems to be without an end. Before you end up a statistic, don’t you think it makes good security sense to protect yourself by investing in some good antivirus software?

Choosing The Antivirus Software That Is Right For You

Go online to any antivirus software site or walk into a local computer store and you will see shelves loaded down with a bewildering selection of software. There will be spam filters for email, firewalls, antivirus scanners for the home computer, antivirus software packages for the home office, antivirus software for the Windows, Mac, Linux, iOS, Android and other platforms. Confusing isn’t it?

A Home or Small Office PC running either Windows or Mac OSX needs the following software programs to protect it from viruses or malware. First, is a two-way firewall to watch for and prevent malware from entering your computer or, if already present, reporting home on a successful infiltration. Next, a good scanner to hunt down and kill those viruses and malware that are already on your system. Supporting the scanner, should be an updating service to find and download the latest information on viruses, how to eliminate them and list sites where they are coming from so you can avoid them in the future. And lastly, email, SMS, chat and IM software to scan and filter out spam, suspicious emails, dangerous attachments and malicious code.

By now you’re thinking, “How much is this all going to cost me?" “How will it affect my system?" and “Will everything play nice together?" Ok, this is where looking at an antivirus suite such as those made by McAfee is a good idea.

Why McAfee Is The Best Choice

As a reputable maker of Antivirus Protection Software, McAfee makes a number of good, reasonably priced software packages for Windows and Mac PC’s that are very effective at protecting your computer against viruses and malware. McAfee Antivirus Plus and its more capable upgrade, Internet Security for Windows are designed to provide you with essential protection and keep you worry free and out of trouble while you are surfing the net. Internet Security for Mac, like its Windows counterpart provides similar protection for Mac OSX computers whether they are on or off the net.

Download ESET NOD32 Antivirus And Smart Security 5 Beta Free

ESET NOD32 used to be my best choice among the security suites for quite a long time. NOD32 Antivirus and Smart Security raised the level of overall competition in the security industry by offering very light weight products. The competitors had to revamp their products in order to look slim and light. But so far very few security companies have been able to beat NOD32 in terms of speed and efficiency.

ESET NOD32 Smart Security 5

ESET NOD32 has finally released NOD32 Antivirus 5 beta and NOD32 Smart Security 5 beta. Let’s look at some of the features added in the new security products:

Parental Control is a new feature in NOD32 Smart Security 5 which will keep your family safe from undesirable websites.

Cloud powered reputation engine makes it faster to scan for malware and provides enhanced detection rates with cloud based whitelisting.

Gamer Mode lets you run the security suite and the antivirus in silent mode. NOD32 will not disturb you with pop ups and other informational messages during your gaming time.

Enhanced Media Control prevents the spread of malware through removable media like USB flash drives, CDs, DVDs etc.

Smarter firewall defends against remote attacks with more robust traffic filtering.

Improved Antispam blocks spam with an even higher level of precision and added log capabilities.

Supported Operating Systems include Windows Home Server, Windows 2000, Windows XP, Windows Vista and Windows 7. Please note that since the antivirus and the security suite are in beta, there may be bugs in the products which may cause some problems for you. So it is never recommended to install these products on your production computers.

Universal USB Installer–Make USB Bootable

If you have a laptop or a computer which doesn’t include a CD/DVD ROM, it will be almost impossible to install any new Operating System except for the one that is already installed. One other way to install the Operating System is to use a USB drive to install the Operating System but you’ll need to make the USB drive bootable. I have already written about Plop which can make any USB drive bootable even without BIOS support.

Universal USB Installer includes almost all kinds of bootable items including Operating Systems and bootable Troubleshooting tools. The list of installable stuff is very long and includes tools from almost all Linux and UNIX distros including Ubuntu, Debian, Mint, Backtrack, OpenSUSE, Puppy Linux, Windows Operating Systems (Windows Vista and Windows 7) and troubleshooting tools like Hiren’s Boot CD, Acronis Rescue CD, Kon Boot, OphCrack etc. Universal USB Installer is a portable utility and is available for Windows only. So you can install any tool in your USB drive using Universal USB Installer.

Universal USB Installer Setup

Since most of the tools are free or open source, Universal USB Installer will give you an option to select the path of the installation if you have it on your computer or it can download it for you. You just have to check the checkbox next to the drop down list after selecting your distro. Or if you have the setup of your distro in the same folder as Universal USB Installer, it will automatically detect it and will skip the step of choosing the path of the distro.

Universal USB Installer Kon Boot

You should plug in your USB drive first before starting Universal USB Installer otherwise it will not be able to detect it automatically. After installation is complete, you can boot your computer with the USB drive and do whatever you want.
