Antivirus, anti-virus, or AV software is computer software used to prevent, detect and remove malicious computer viruses. Most software described as antivirus also works against other types of malware, such as malicious Browser Helper Objects (BHOs), browser hijackers, ransomware, keyloggers, backdoors, rootkits, trojan horses, worms, malicious LSPs, dialers, fraud tools, adware and spyware.Computer security, including protection from social engineering techniques, is commonly offered in products and services of antivirus software companies. This page discusses the software used for the prevention, detection, and removal of malware threats, rather than computer security implemented by software methods.
The brand AVG comes from Grisoft's first
product, "Anti-Virus Guard", launched in 1992 in Czechoslovakia .
In 1997, the first AVG licenses were sold in Germany
and UK .
AVG was introduced in the U.S.
in 1998.
The AVG Free Edition
helped raise awareness of the AVG product line.
In 2006, the AVG
security package grew to include anti-spyware, as AVG Technologies acquired ewido Networks, an anti-spyware group. That
same year, Microsoft announced that AVG components would be available directly
within the Windows Vista operating system.
AVG Technologies
acquired Exploit Prevention Labs (XPL) in December 2007, and incorporated that
company's LinkScanner safe search and surf technology into the AVG 8.0 security
product range released in March 2008.
In January 2009, AVG
Technologies acquired Sana Security, a developer of identity theft prevention
software. This software was incorporated into the AVG security product range
released in March 2009.
According to AVG
Technologies, over 106 million users have AVG Anti-Virus protection, including
users of the Free Edition.
AVG Technologies provides a number of products
from the AVG range, suitable for Windows 2000 onwards. In addition to this, AVG
Technologies also provides Linux, FreeBSD, and most recently Mac OS X versions
of the software. AVG Anti-Virus 9.0 is available in free and commercial
editions. AVG 9.0 has identity theft protection through a partnership with
Intersections Inc., AVG 9.0 also adds white listing, behavioral protection and
cloud operations to their signature-based blocking. The software adds the
Resident Shield, firewall, and identity protection modules. The LinkScanner
component has been improved to cut phishing threats further. Version 9 was the last version
compatible with Windows 2000.

AVG Anti-Virus Free
Edition provides basic,
Anti-Virus and Anti-Spyware protection, plus the full AVG LinkScanner safe
search and surf technology. There are some limitations with AVG Anti-Virus Free
Edition compared to the commercial versions of AVG products and other free
antivirus. These limitations include:
·
Less protection – AVG Anti-Virus Free Edition provides the
same anti-virus and anti-spyware scanning engine as the commercial product;
however, it lacked anti-rootkit protection
until 2010. The older 7.5 Free Edition is perfectly capable of finding and
disabling rootkits based on signatures, but cannot scan for rootkit-like
activity. The 8.5 version of AVG Anti-Virus Free Edition version lacks any
anti-rootkit capability. While there is no official protection for files from
messaging sources, the Resident Shield component
automatically scans files before they are opened or copied.
·
Infrequent updates – AVG Anti-Virus Free Edition receives
updates via a lower priority service. Priority updating via high-speed servers
is only available for the commercial versions of AVG products.
·
No telephone or e-mail technical support – There is no
telephone or e-mail technical support provided by AVG for users of AVG Free
Edition products anywhere in the world. AVG Free Edition users have access to
support via the self-help AVG Free Forum.
·
Less customization – Scheduling options in AVG Anti-Virus
Free Edition are very limited (only one scheduled update per day). However, the
AVG Resident Shield configuration allows exclusions. The on-demand/scheduled
scanner allows advanced testing options such as heuristics and reporting of
password-protected archives reporting. Process priority for on-demand/scheduled
scans can be dynamically adjusted over three different configurations.
·
No server support – AVG Anti-Virus Free Edition cannot be
installed on server operating systems (such as Windows Server 2003), nor can it
be used for the scanning of network drives. Note, the newer AVG 2011 free
edition can be installed on Server operating systems like Windows Server R2.
·
AVG Anti-Virus Free Edition is only licensed for home and
non-commercial use on a single computer.
