Buying a good anti virus software package is important for protecting the investment in your computer. Whether it is a desktop or a laptop, computers are expensive and fragile with tons of intricacies that are easily damaged by an internet virus. Any computer that accesses the internet can be vulnerable. The damage from infection can range from a mild slow-down of processes to serious, even fatal damage to the hard drive. Luckily, there are a multitude of antivirus packages available on the market that will protect your investment to various degrees depending on the level of protection you pay for.
The most important feature is reliable virus protection. Since there are so many ways to be infected, it is important to protect the computer from all possible sources of danger. An effective virus protection software will include link scanners for safe web surfing, constant monitoring for infections, e-mail scanning, download monitoring and an option to set custom virus scans that will detect and quarantine problem files.
It is also important to include a firewall in your anti virus software purchase, since virus protection alone will not prevent malicious threats such as outside sources that may piggyback on a connection to harvest personal information such as credit card numbers or account information. By monitoring which network transmissions are allowed and which are blocked as unauthorized, a firewall will keep internet threats from tampering or otherwise compromising the security of the computer and its network. They work based on a set of rules, which creates a specific list of criteria that determine what type of transmissions the firewall will block.
Since spyware is a major problem connected with internet use, antivirus software should contain some form of anti-spyware software or be used in conjunction with alternate software. Spyware usually works maliciously to collect user-specific personal information, which can lead to identity theft and other serious problems. Having a quality firewall with secure rule lists can help prevent loss of information to spyware, but spyware-specific software will help target dangerous programs and remove them immediately, preventing loss of valuable information.
Adware can also be a significant problem, although it generally does not lead to viruses and therefore is not included in all antivirus packages. Adware can bog down system processes and cause the system to run more slowly. It also installs unwanted toolbars and can track user search information and key logs, which the software uses to produce even more advertising. Choosing a software package that detects and removes adware can help keep internet surfing free of pop-up ads and can also keep the system running smoothly without interfering processes running in the background.
Not all antivirus packages contain every feature that users need, with only a select few featuring virus protection in conjunction with firewalls, anti-spyware and anti-adware software. Some inexpensive software may feature only a few of these protection mechanisms, but ideally, the software should include all features for the highest level of protection. Usually these are available for a premium price, which is well worth the additional subscription fee for the amount of protection offered.
