Why is Anti Virus Software so important?

It is very important to have anti virus software and other protective software installed on your computer to protect you. Without any of this protection on your computer you are vulnerable when you are on the internet to fraud and computer vandalism. So it is very important that you get legal and professional quality anti virus software programs; there are many of these that are offered online for free.  These free anti virus downloads will detect and eliminate the viruses from your desktop and your network.  Anti virus software constantly protects your computer with scheduled virus scans and automatic detection of attempts to hack your computer.  The free anti virus programs, like those that you pay for, update the virus definitions daily and will send those updates for you, or you can switch to a daily manual check if you prefer. It is critical that you take advantage of these updates since new viruses are created and executed every day.
Free anti virus software isn’t the only thing you need, however. If you do not have a reputable anti spam software running on your computer you will most likely be inundated with an avalanche of junk mail, more commonly called “spam”.  Freeware anti spam software programs are simple to install and kill spam without taking up much room on your computer.  In fact, many of them are surprisingly small. They support most major clients and update themselves so you can be sure you have the most current software. This software does not delete the spam but puts it in a folder, usually labeled “spam”, that you can examine periodically and unmark those that you don’t want categorized as spam. It is simple to do a search for freeware anti spam and you will get a large selection of anti spam protections.  This is quite an improvement from the black lists and white lists we used to have to make in order to filter spam.  These were also ineffective!  The current crop of anti spam software make it very easy to avoid those annoying emails. 
Another great protector for your computer is the anti Trojan software. Trojans, sometimes called Trojan Horses, aren’t viruses themselves but are pieces of malware that can transmit a virus.  They are also notorious for installing “backdoor” entries so that your computer can be hacked.  Anti Trojan software will remove Trojans and their viruses from your computer.  The free anti Trojan downloads will scan, remove and then protect your computer from other malicious software like worms, dialers, viruses, spyware and adware. This is why it is so important to do a search and find some good programs that are free so you don’t have to pay expensive prices to protect your computer.  Anti Trojan software for free is often just as good or better than those you have to pay for. 
There are also free programs that specifically address the problem of spyware that other software may not catch.  Updated frequently and sometimes on a daily basis, they will prevent spyware from installing itself on your computer or even getting close to it.  There is no harm in having as much preventative software as possible to protect yourself as long as they are compatible together.
