Consider your needs before purchasing antivirus software, as most come with a suite of programs. Check the virus database and update frequency, and consider additional programs such as firewalls and parental controls. Free options may suffice, but beware of malicious programs posing as legitimate antivirus software.
Antivirus software can be a powerful tool for keeping your computer safe, but there is some information you should consider before making a purchase. Most antivirus software comes as a suite of different programs, such as firewalls, virus and malware scanners, parental controls, and other options. Before buying antivirus software, determine which programs and features you actually need. It’s also important to choose a regularly updated suite, because new viruses and other malicious software will appear regularly. Another factor to consider before buying antivirus software is that a free security suite may be able to meet your needs.
The main purpose of antivirus software is to scan a computer for malicious code and then quarantine or remove it. These programs rely on databases of information about known viruses, so if a particular virus has only recently been created, it may escape even the best virus scanner. Before buying antivirus software, it’s usually a good idea to check how comprehensive the virus database is and how often it’s updated. If an antivirus program has an outdated or poorly maintained database, it may not offer the kind of protection you’re looking for.
Many antivirus suites also include a variety of other programs in addition to basic virus scanning. Before purchasing antivirus software, you should identify the security programs you need or are interested in. A common option is a software firewall, which is a program that can regulate the flow of information into and out of your computer by preventing unauthorized connections. Another option that may be offered is malware protection, which can deal with a variety of spyware, adware, and other threats that most simple virus scanners fail to scan for. Some security suites also come with parental access controls, which can be useful if you have children and want to regulate their Internet access.
In addition to the various commercially available antivirus suites, there are also many free options. Before buying antivirus software, check the features available from free security suites to see if they can meet your needs. It is also important to check any option before settling on it, because there are some malicious programs that are advertised as legitimate antivirus software. Some of these programs can actively infect your computer with additional viruses, so it’s always important to deal with reputable software vendors when purchasing antivirus software.
