AVAST 8 – free antivirus

Avast Free Antivirus 8 is one of the best free antivirus that is available to Microsoft windows users. Avast uses very less RAM and is fast in response. It has a lot of features which most other free antivirus don’t have. Avast is very highly customizable. Avast provides cloud based virus detection if your computer is connected to internet. Very low impact on system performance.

Apart from antivirus and anti-spyware there are other features. P2P shield and Instant messenger shield supports many softwares. This I have not seen with other antiviruses and is very appreciable.

Additionally avast provides mail shield which checks mail for malware and other threats. It also has network shield generally not found other free antivirus. It also has script shield which protects your computer from running dangerous scripts.

Note : You need to have live working internet connection in order to activate Avast for 1 year.


  • Antivirus and anti-spyware engine -State of the art scanning engine provides reliable protection against viruses, spyware and other forms of malicious software.
  • Real time anti-rootkit protection -Unique “on access” technology checks all kernel-mode drivers that the operating system is loading for signs of rootkit behavior. This enables even unknown rootkits to be detected and stopped before they can do any damage.
  • Avast! Community IQ – Most samples we process come from sensors deployed throughout the avast! community in the Behavior shield and anti-rootkit modules. This is a unique source of data made possible only thanks to our huge user base. Most of the collected samples are analysed by a number of automated processes and only a small fraction of the samples need to be processed manually by our virus analysts.
  •  Code emulator – When a suspicious executable is encountered (during both on-demand and on-access scanning), avast! is able to emulate the program’s code in an isolated environment. The code emulator is used for two purposes. First, it is used for generic unpacking. Secondly, it is used in the heuristics engine. Technically, this is done using dynamic translation, a method much faster than traditional emulation techniques.
  •  Heuristics engine – avast! features a new heuristics engine designed to proactively detect malware undetectable with normal definitions. The heuristics engine is able to cover both binary (executable) and script malware.
  •  Potentially unwanted programs detection – avast! detects potentially unwanted programs, such as remote admin tools and commercial key loggers. Custom rules can be set for dealing with these types of programs.
  •  Boot-time scanner – Allows you to scan your computer for infections before the operating system has started and before a virus can be activated (32-bit operating systems only).
  •  Command-line scanner – Enables you to run a scan directly from the command line.
  •  Wake-up for scan – Microsoft Windows is woken from sleep or hibernation mode, performs a scheduled scan, then returns back to sleep mode.
  •  Scheduled scanning – Allows users to define the scan time and files to be scanned.
  •  avast! Intelligent Scanner – Can reduce the number of required file scans by up to 80% through a white list of proven safe applications. Files identified as safe are not rescanned unless they change.
  • Behavior Shield -Monitors activity on your computer using a number of sensors (file system, registry and network based) and reports/blocks any suspicious behavior.
  • Behavioral Honeypots – avast! sensors identify and monitor suspicious file activity on selected computers, automatically submitting files to the Virus Lab for additional analysis.
  • File System Shield – Real-time scanning of opened/executed files.
  • Mail Shield – Scans all incoming/outgoing e-mails for malware. For MS Outlook, a special plug-in is used. Other email clients are protected by a generic POP3/IMAP4/SMTP proxy. New in version 5, the proxy also supports scanning of SSL communication (gmail.com, sympatico.ca, ….)
  • Web Shield – Scans all visited web pages and checks all files, pages and java scripts downloaded from the internet. Thanks to the Intelligent Stream Scan feature, the Web shield doesn’t slow down your web browsing.
  • P2P Shield – Checks files downloaded using P2P programs. – ABC, Ares, Azureus, BearShare, Bit Torrent, BitComet, BitLord, BitPump, CZDC++, Direct Connect, eDonkey, eMule, iDC++, iMesh, Kazaa, Kceasy, LimeWire, Morpheus, Opera’s DC++, Overnet, Qtrax, Shareaza, SoulSeek, StrongDC++, uTorrent, Vuze, WinMX, Winny2, Zultrax.
  • IM Shield – Checks files downloaded while using instant messaging or “chat” programs. – AIM (AOL Instant Messenger), Gadu-Gadu, gaim/Pidgin, Google Talk, ICQ, IM2 Messenger, Infium, Miranda, mIRC, MSN/Windows Messenger, Odigo, PalTalk Messenger, Psi Jabber Client, QIP, QQ, SIM, Skype, Tlen, Trillian, WengoPhone, XFire, Yahoo! Messenger.
  • Network Shield – Provides protection against network-based viruses. The module has two main components: a URL blocker, designed to block malicious URLs (as defined by the Virus Lab), and a lightweight intrusion-detection system.


  • Firewall – It does not have firewall. You you would be left unprotected from hackers attack. So keep windows firewall ON all the time.
  • Spam filter – It does not have spam protection. So email application won’t get spam filtered. Still web mail service like gmail and yahoomail will be unaffected by not having spam filter.
  • Online shopping & banking protection – It does not have any feature to protect your confidential credit/debit card data or banking data from being stolen.
  • Web filter and parental control
