Make sure that your antivirus program is running and up to date

Antivirus programs play an immense role in functioning of a PC. The main purpose of this kind of program is to prevent a user’s computer software get “infected” with harmful programs coming from unverified sources (other computers) or from the Internet. These harmful programs can spoil the installed software, slow down the process of a computer performance and cause other unwanted consequences. Spying virus software can steal user’s passwords and/or other personal information, copy and resend important data to other people who can misuse the obtained information.

Antivirus programs provide a reliable hedge against illegal hackers’ attacks, spying agents and other software. These are recommended to be installed on any computer with the option of being in a permanent “on” mode. As a rule, all kinds of modern antivirus software have got a function of constant monitoring of a computer system which starts when a PC gets switched on. The logotype of a current antivirus program available on a PC indicates the “active” functioning of a program. Now, it provides permanent control over Internet traffic and other information coming to the computer from external sources (disks, Bluetooth, a flash drive etc.). In case of any danger, antivirus program signalizes a user about it and offers several options: complete drive scan (including hard drive, network, flash and disk drives); restrain access (external source is not accepted); cure (removes virus from a data medium); move to quarantine (continues monitoring with no sharing of a presumably “infected” file with the PC system) and other choices that help manage the software and choose a correct action.

Antivirus programs can be found for sale on the free market on the licensed disks or on the Internet. Here one can download desired AV software and register it by purchasing a registry key online. Individuals are given an opportunity to take advantage of demo versions of many anti-virus software applications for free. It must be mentioned, that demo versions do not offer certain services available with registered ones.

Users are advised to monitor the expiration date or demos and paid updates in order not to let a PC remain unprotected.
