Anti Virus

Anti Virus AVG
AVG Free provides the bare necessities when it comes to security, but that should be enough for savvy Windows users. You'll get a combined antivirus and antimalware engine, LinkScanner, and e-mail scanning. AVG Free 9 introduces a few new features, with improvements focused on performance, including claims of faster scan and boot times. One new feature is the Identity Theft Recovery Unit. Only for users in the United States, ITRU is a business partnership with Identity Guard which provides "consumer identity theft solutions," accessible only from the AVG toolbar in Firefox and Internet Explorer.
The interface is nearly unchanged from the last version, and generally it's easy to use. From the main window, though, you must double-click to get further information on any feature, whether virus scanning, LinkScanner settings, or updating. Streamlining this to one click would be helpful. A scheduling utility automates both scans and updates, while the upgrade ad at the screen's bottom can be easily hidden using the Hide Notification button. When starting a scan, a slider makes it easy to jump between Slow, Automatic, and Fast scans: the faster the scan, the less comprehensive it is, so users should take advantage of the scan optimization that is recommended during installation to speed up that first scan. A progress meter for regular scans would've been useful, though. Should a virus create serious problems, AVG creates a rescue disk to scan your computer in MS-DOS mode.
The LinkScanner feature protects you from third-party code exploits before they load in your browser and for ranking search results. Annoyingly, when you install its optional toolbar, it commandeers your new-tab page, decidedly inappropriate behavior. The program doesn't obviously tax your system when scanning or when running in the background, although CNET Labs determined that it will significantly slow down your system's boot time, and slightly delay shutting down. AVG also detected some image files as threats, when two other scans decided they weren't--we decided these were false positives. AVG might not be the fastest or the most effective free security option, but it still gets the job done and you're better off with it.


Avast Anti Virus
Avast Free 5, an A-list freeware antivirus app, provides the same steadfast protection of well-known, pricier antivirus programs. Avast is remarkable for both its effectiveness and arguably providing the most complete free antivirus on the market.
Avast Free 5, formerly known as the Home Edition, protects you with multiple guards. The antivirus, antispyware, and heuristics engines form a security core that also includes multiple real-time shields. The adjustable mail and file system shields join the pre-existing behavior, network, instant messaging, peer-to-peer, and Web shields. The behavioral shield is a common-sense feature, as security software publishers leverage their large user bases to detect threats early and warn others. Other new features include a silent-gaming mode and an "intelligent scanner" that only looks at changed files after establishing a baseline. The biggest change in Avast 5, though, is the interface. Gone is the music player default look, which was skinnable but confusing. In its place is a sleek UI that new users should find far more manageable. It's also Aero-friendly, with Explorer-style navigation buttons in case you can't remember where you tweaked a particular setting.
Avast's recent independent third-party testing has been notably solid, able to hold its own against better-known programs from Symantec and Microsoft. Avast 5 Free lacks features in the paid upgrade including antispam measures, a testing sandbox, a Script shield, and a firewall. Even without those, Avast Free 5 is probably the strongest, free antivirus currently available.

Avira Anti virus
Avira's AntiVir has been a player in the security world for some time; however, in 2008 its status boomed because of its remarkably strong detection rates. It still remains near the top of independent antivirus efficacy tests, but while the 2009 version more or less kept pace with the competition, the 2010 edition isn't quite as good as it could be.
Both longtime and new users alike will note the pop-up ad that appears whenever a program update is downloading; it has been the unaddressed focus of critical and user dislike for several years. While the occasional ad that interferes with a user's work flow used to be considered tolerable for effective free security, that's no longer the case. Avira's lack of a silent-running entertainment-gaming mode is also noticeable, since so many free and paid competitors now offer the mode.
Except for the most cosmetic of changes, the app's interface is unchanged from version 8. There are new icons on the program's toolbar, a new static image background, and that's about it. The main window offers a left-side navigation menu with drop-down menus and a central pane to see more detailed information. AntiVir opens to the Status menu, informing you of your last scan, your last definition file update, whether the real-time guard is active; however, Avira removed the premium upgrade link in this version. The Events screen logs changes to the program and the Reports tab keeps a history of threats--information from both sections can be exported.
New features are a bit thin in the free version of Avira 10, too. A new generic-repair mode really just takes the choice out of how Avira tells you about the threats it has discovered. In version 9, you could be informed about them in the middle of a scan or at the end; however, now only the latter is available. Windows 7 users now have the capability to run a scan as an administrator directly from the interface, which is a smart, but minor improvement. Avira's installation sequence has been revamped, and now only takes users through five windows. Theoretically, this means it's a five-click installation, but new users will have to complete the registration form. However, its installation file unpacking process appears faster, and you no longer have to reboot after the install.
This isn't to say that AntiVir Free 10 isn't stuffed with robust features. The program offers a wide selection of scan customization, letting users fully scan both internal and external hard drives, run a preloaded scan--for rootkits, for example--or customize a scan. On a real-world computer, the full scan took about 1 hour and 12 minutes, which is average. Avira includes antispyware protections, scanning tech that can crack open "locked" files, improved internal security to prevent AntiVir's files from being maliciously altered, and one-click threat removal--baby-sitting was taken out in the last version.
The Local Protection and Administration navigation options reveal the Scanner, Guard, Quarantine, and Scheduler features. Combined with the Configuration button located at the top of the central pane, users can customize scans as necessary. When Avira quarantines a file, its information is on display along with options to scan it again, restore, delete, and e-mail the file to Avira. The apps rebuilt heuristic engine retains the same choices from the previous version had, and it can be turned on or off in part or in full and offers three intensity levels. Not counting the lively user forums, Avira's included help features are good for a free antivirus app, with mouse-over information on each feature. The scheduler, once a major Avira selling point because it was light-years ahead of other free security suites, has now been caught up to by its competitors.
AntiVir 10 doesn't require a special uninstallation tool, unlike many competitors do. In the end, Avira's free suite makes for an excellent backup suite, but its competitors have since caught up with or surpassed what it can do.

SMADAV

Smadav 2010 Rev. 8.2 dirilis !!!

Smadav 2010 Rev. 8.2 : Penambahan database 80 virus baru, perbaikan false alarm, penambahan teknik heuristik untuk varian virus penginfeksi exe, dan beberapa perbaikan bug lainnya
Smadav 2010 Rev. 8.1 : Penambahan database 100 virus baru, Smadav Virus Scanner Engine terbaru (SmadEngine.dll), dan sudah kompatibel penuh untuk Windows Vista & Windows 7.
Smadav 2010 Rev. 8 dirilis dengan berbagai fitur dan penyempurnaan baru yang dikhususkan untuk pemberantasan virus lokal. Fitur-fitur itu seperti Smad-Behavior yang bisa mengenali virus lokal baru yang belum ada di database Smadav dari tingkah lakunya ketika menginfeksi sistem. Smad-Ray yang bisa melakukan scan flashdisk secara otomatis setelah terpasang hanya dalam waktu maksimum 5 detik. Smadav 2010 lebih stabil dan sangat disarankan untuk digabungkan dengan antivirus internasional karena Smadav hanya bisa menangani virus lokal. Pengebalan flashdisk (menggunakan folder autorun.inf) telah disempurnakan lagi dan sebelumnya akan ada konfirmasi sehingga Anda bisa memutuskan apakah suatu flashdisk ingin dikebalkan atau tidak.
Sebagai informasi, dari sampel-sampel virus yang di-upload pengguna ke situs Smadav.net, penyebaran virus lokal saat ini sudah mulai turun drastis di Indonesia. Mungkin ini dikarenakan sudah banyaknya antivirus lokal yang bisa membasmi virus-virus lokal. Dan juga karena pengguna Windows XP yang sudah berkurang karena sebagian sudah meng-upgrade sistem operasinya menjadi Windows Vista atau Windows 7 yang sangat aman dari infeksi virus khususnya virus lokal. Penyebaran virus di Indonesia lebih banyak didominasi oleh virus dan malware internasional yang tentunya tidak bisa diatasi Smadav. Anda wajib dan sangat disarankan menggunakan antivirus internasional untuk perlindungkan komputer Anda dari virus dan malware internasional ini.

Anti Malware
Malwarebytes Anti-Malware is a surprisingly effective freeware antimalware tool. It's a relatively speedy malware remover, with the quick scan taking about 8 minutes even with other high-resource programs running. The heuristics engine proved on multiple computers during empirical testing that it was capable of determining the difference between false positives and dangerous apps.
The app has some nice features rolled in, too. It supports multiple drive scanning including networked drives, context menu options including a scan-on-demand for individual files, and the FileAssassin option under the More Tools section for removing locked files. The interface is simple, but pleasant-looking and well-organized. Tabs live just below the oversized logo, with few options per tab to keep down the clutter. The installation process was fast enough, but interestingly offered up the well-kept changelog and an instant definition file update.
Do note that the real-time protection is restricted to the paid version, as is the scheduler for updates and scans. Overall, though, Malwarebytes Anti-Malware is a responsive malware remover that does what it should with a minimum of fuss.

Norton Anti Virus 2011
Norton AntiVirus 2011 review The bottom line: You get less, for less. Norton AntiVirus 2011 offers the same core high-quality computer and networking protection features as its more full-featured sibling, Norton Internet Security, but it lacks some key Web protection features that users shouldn't really go without.
Review:
Editors' note: Portions of this review are based on CNET's review for Norton AntiVirus 2010.
Over the past few years, Symantec has completed a course reversal for its Norton consumer Internet security suites. The massive package of security tools works better than it ever has before, with an impressive set of features, some useful new tools including the free Power Eraser, and third-party security efficacy benchmarks that are nothing short of remarkable. Meanwhile, CNET Labs' performance benchmarks indicate that though Norton doesn't leave the smallest footprint on your system, users should see a minimal impact overall.
Installation
For the second year in a row, Norton's former sluggish beast now offers a smooth and fast installation operation. Once you run the installer, the program is ready to operate in about a minute--impressively fast, and doubly so considering past performance. The installation process is also the first time that you will interact with Quorum, Norton's behavior-based detection engine. You'll be asked to participate by sending anonymous data to Symantec's cloud. Opting out of the data submission, according to Symantec, will not affect your security.
Running the trial of Norton also requires registering the program. Like many programs, Norton used to force open your default browser and take you to the company's registration Web site. One of the new features in Norton AntiVirus 2011 is that the program comes with a Web interface for your desktop. Users first encounter this when registering, but it pops up in regular program usage as well, keeping users from being forced to open their browsers to manage certain Web-based features. Uninstalling the software left about 10 Registry entries behind, but no other traces were detectable. Overall, Norton's installation experience was fast and hassle-free, with a minimum of configuration options--but the ones that did come up appeared necessary.
