Everyone who has been on line for over a few weeks has heard of computer viruses. Loads of surfers have had them and many surfers have them yet do not know it. Not all computer viruses are intended to do damage to the infected computer. Some viruses are intended to steal valuable data such as account numbers and passwords and other viruses are intended to record where you go and what you are interested in.
This information, once garnered, is sent back to the virus’ master who will use it to either steal from you or spam you to death with deals based on the words that you have typed into your keyboard. These viruses are also known as tracking cookies. There are also Trojans (Trojan horse), worms and bombs.
There are firms that supply free of charge or sell anti-virus software which is intended to protect your computer from these computer viruses. However, because up to several dozen of these viruses are released on a daily basis, you need to have the virus database of your anti-virus software up-dated on a daily basis as well. The anti-virus (AV) software virus database is full of all the virus patterns on hand so far.
It has been estimated that 80% of viruses are meant to destroy data on the computers they infect. That is, they will destroy the file allocation table of your main disk drive rendering it unreadable, but different viruses do different jobs. I had a virus in December that wiped out my Outlook address book. Two weeks later as I was refilling the address book, and it wiped it out again.
There are a few jobs you can do to minimize your danger of picking up computer viruses. The first thing you have to do is install an AV programme and adjust its settings. Some of the free AV software is as good as some of the purchased AV software, but if you would like the best, you will have to pay for it. It is not expensive – less than $50 a year – especially when you compare it with the cost of repairing a damaged computer.
Once you have selected and installed your AV software, check the options and instruct it to check all incoming and out-going files – that is downloads, uploads and emails. If it will not check emails, it is no good, get another one. Then instruct it to update the pattern files (database) automatically or daily.
Update your patterns and then perform a complete system scan – it can take hours. Then, set the AV software to scan your computer once a week at some time whilst it will be on, but not in use. I do mine at 2 AM on Monday.
Be wary. Be as suspicious of downloading as you are of strangers prowling around at dusk. Never download from porn sites. Be wary of small files. Most viruses, like their living counterparts are tiny. Therefore if you would like to download a film or some music and it is much shorter that usual, be careful or do not do it. Be suspicious of attachments to emails from people you do not know.
Acquire anti-spyware software and run it regularly or / and set your browser to dump all cookies at the end of a session (clearing out privacy). If you regularly run into difficulties after dumping the cookies of a site you go to often (like Google), then add them to your ‘Trusted Zone’. Computer viruses are out there and can have costly consequences, but you do not have to get them, if you take a couple of (free) precautions.
