Anti virus software question?

Question

What are some good anti-virus protection for my home computer? I was not too thrilled with Norton, but that was a few years back, so maybe it got better? Is there anything that will protect me well if I use Limewire to download music?

Answer 1

AVG Free is the best anti-virus out there right now. Norton is total junk, uses up a lot of system resources and you have to pay for it. Avast is another free anti-virus, which is still good, but personally I like AVG. You can download AVG from the link below. There is absolutely no spyware.

Checking engine
The heart of AVG Anti-Virus is the checking engine - you can imagine it as a "black box" into which requests to check objects enter and the box returns information indicating if these objects are virus-free or infected.

The checking engine includes an application interface for communication with other AVG Anti-Virus components (Resident Shield, Tests, E-mail scanner modules and plug-ins etc.) which use this service. It was created with an emphasis on AVG Anti-Virus modularity and is common for all mentioned components.

Detection methods
Efficiency in detecting infected files is guaranteed by using a combination of different detection levels. Before the check itself, the file is pre-processed, which involves removing any parts unnecessary for virus analysis. A quick scanning process is achieved by this technique.

Known virus detection
This is the simplest technique in which files are checked for the presence of virus identifiers (a sequence of bytes characteristic for an exact virus). Based on this kind of detection, detailed analysis is performed to identify the exact infection.
Generic detection
This is a more common method for the detection of known viruses and is used to determine new variants of known viruses. If no known virus is identified, generic detection looks for sequences within the file typical for certain viruses. Such sequences usually don't change within the virus when it is modified, even if the behavior of the new variant is different. This method is effective especially in the detection of macro-viruses and script-viruses.
Heuristic analysis
The last method for detecting viruses (where previously mentioned methods were not successful) is Heuristic analysis. Its skillfulness lies in its capacity to (in some cases) detect a virus which is not included in the internal virus database. During Heuristic Analysis, two methods are used:
Static Heuristic analysis - looking for suspicious data constructions
Dynamic Heuristic analysis - code emulation: this means the file is started inside the protected environment of a virtual computer inside AVG. The file is analyzed for actions typical for viruses. An example being an application which when run looks for other executable files in order to modify them.
Detection levels
AVG E-mail Scanner (EMS)
E-mail checking is supported either directly by plug-ins for certain applications (Microsoft Outlook, Eudora, The Bat!) or by Personal E-mail scanner - AVG EMS works at POP3 and SMTP protocol level. EMS can also protect e-mail communication of all other E-mail clients (for example Outlook Express). Each E-mail client plug-in can be individually configured to have its own testing configuration including the language definition for certification texts.

With AVG EMS, it is possible to filter attachments by their extensions or by their content
The solution at POP3/SMTP protocol level is independent of the E-mail client used
It is possible to protect multiple e-mail accounts and to check multiple e-mail servers
SMTP authentication is supported
Tests - ON-DEMAND check
On-demand checking of files or system areas can be performed in three ways:

Scheduled Tests
By default, the Complete Test is set to be started every day as scheduled to ensure the basic functionality of this level of protection. From the User Interface it is possible to create new Tests and to set when and what should be checked and what to do in case of infection.
Manually started Tests
It is possible to start defined Tests from the User Interface whenever required. An example would be the Removable Media Test.
Windows Explorer extension included in AVG integration into Windows
This is a simple and very quick method of checking a specific file. You can use the Windows Explorer environment by right-mouse-button clicking on the appropriate file and selecting the option "Test by AVG".
Resident Shield - ON-ACCESS check
Resident Shield protects the computer whenever the operating system is running. It works in the background and ensures transparent anti-virus file checking during file opening, executing and optionally during file saving. Resident Shield runs automatically. If a virus is detected, Resident Shield denies opening or running of the infected file. Resident shield stores information about files it has checked eliminating the need to recheck them if no modifications have been made.

Update
It is vital for successful virus detection to keep your AVG installation up-to-date. AVG Anti-Virus offers you several ways to keep it up-to-date, including a fully automated update process.
