 Avast 5 Free Antivirus 

Avast! Free Antivirus is a reliable antivirus software solution designed to provide computer users with effective protection against viruses and spyware.

Avast comes with well-organized interface that targets beginners and professional users alike, with all features being clearly displayed right in the main window.

Be careful during the installation though, because the setup kit also attempts to drop a separate browser on your computer, although Avast doesn’t need this kind of app to work properly.

However, once installed, Avast works simply great, with virus definitions updated even several times a day. The scanning process is very fast and is quite light on hardware resources, but it all depends on the computer and the files you’re about to scan.
We were pleased with its speed during our tests, even though sometimes we were a bit annoyed by the boot-time scanner.

The boot scanner is actually a very handy function because it attempts to scan the computer before the operating system is fully loaded and thus before any virus is ready to take control of certain system files.

There are four scanning modes, as follows: “Quick Scan”, “Full System Scan”, “Removable Media Scan” and “Select folder to scan”; the latter allows for an in-depth scan of a user definded location. The “Quick Scan” mode takes just a few minutes, while the “Full System” mode can last for more than a half an hour, depending on the size of the drive and the amount of data stored locally.

In addition, Avast comes with dedicated tools to protect multiple apps running on your computer, so it also comprises a “File System Shield”, a “Mail Shield”, a “Web Shield”, a “P2P Shield” to protect peer-to-peer programs, an “IM Shield” for instant messaging clients, a “Network Shield”, a “Script Shield” and a “Behavior Shield”.

All in all, Avast is a must have if you’re looking for a reliable antivirus solution and, as far as we’re concerned, this application is indeed serious competition for other elite software tools belonging to this particular category.

Its features include:

• ·      Anti-spyware built-in
• ·      Web Shield
• ·      Anti-rootkit built-in
• ·      Automatic updates
• ·      Strong self-protection

Panda Cloud Antivirus 1.0

Panda Security has announced the beta version of its Panda Cloud Antivirus, a free cloud-based antivirus thin-client with less impact on PC performance by about 50 percent.

Panda Security’s this latest protection model uses a thin-client agent and server architecture that efficiently blocks malware. It offers effective protection against new as well as unknown viruses by shifting the malware scanning and determination process to the cloud and also by applying non-intrusive interception techniques. This lightweight thin-client hardly uses any PC resources.

Unlike the traditional antivirus products that utilize local PC memory and CPU resources, the Panda Cloud Antivirus thin-client agent is a fusion of local detection technologies and real-time cloud-scanning that helps minimize resource consumption.

“We truly believe that Panda Cloud Antivirus represents a quantum leap in protection over the traditional approach to antivirus,” said Juan Santana, CEO for Panda Security. “Panda Cloud Antivirus offers consumers a truly install-and-forget solution that delivers the industry’s fastest protection against the newest malware with literally half the performance impact. We’re excited to make it available today for free, which is Panda’s way of paying back to the community and growing our Collective Intelligence network so that we can deliver even greater protection to all customers.”

With an average consumption of 17 MB of RAM and 50 percent of the PC performance impact, it includes local and remote antivirus, anti-spyware, anti-rootkit, heuristics and goodware cache.

Collective Intelligence, company’s proprietary cloud computing technology helps automatic identification and classification of new malware in almost real-time. Collective Intelligence automatically classifies each new file it receives.
