Installing Antivirus Software

There was a time when computer viruses were very infrequent, and in general they were not easily mass-distributed. However, in the age of the World Wide Web and email, computer virus proliferation has increased exponentially. Unfortunately, newer and more powerful computer viruses are being created every day, so simply installing antivirus software is not enough anymore. It is also necessary to subscribe to an antivirus service that will keep your software constantly updated so that it can recognize new and emerging threats to your computer's security.

Nearly all antivirus software packages have a subscription service like this already integrated into the user interface. Typically, subscriptions are available one year at a time for a fixed price. There are also some internet based virus scanning websites that will search your computer and identify any threats.

The problem with this kind of system is that it can only tell you what viruses your computer already has; it cannot warn you before the viruses have been placed on your computer. There are also free antivirus software packages that also offer regular no-cost virus definition updates. Usually, this kind of software will perform scans at regular intervals and also detect any attempted breeches of your security in real time. The software will also hint at more advanced capabilities, but they will not be available to the users of the free version.

The types of capabilities offered for an additional charge are utilities such as adware blockers and spyware removers. These features are generally included in the annual subscription costs of traditional, fee-based antivirus software suites. These additional features are intended to protect your computer from dangers other than simply viruses.

Such threats include programs that are maliciously installed without your permission in order to spy on your computer usage. These programs, also called "spyware," are often able to report your personal information to unauthorized people. There are free versions of this type of software, and when used in conjunction with free antivirus software, you should be able to put together a strong defence at no cost.
