Typical Virus Threats and How to Eliminate Them

by Keith Williams

Computer viruses are malicious threats which can attack our computer operating systems, similar to the attacks of viruses on our immune system. Its main purpose is to cause grievous harm if not stopped, and these threats are even able to spread to other computers systems that our PCs come into contact with.

During the course of time these threats have taken many forms and disguises. Two typical types of deception they use may be compared to examples we find in nature and history, they have even been given the same names as well. The first one is called a worm and causes grievous damage to your system without being noticed. The most common worm virus is called MyDoom. Then we have Trojans, which act as the Trojan horse which attacked Troy. It attempts to gain our trust and is all lowed access to computer systems. Here it goes about its destructive activity. One of the well known Trojan computer viruses is called the Dloader-L virus. These dangers are always around and are able to invade non-protected computer systems. Having an insight into how they operate will assist us in identifying and eliminating these dangers from our PCs.

Antivirus software is successful in dealing with many of these malicious variants. They are often able to detect and eliminate these dangers from your computer system once they expose themselves. Amongst these viruses are those which use encryption to render themselves undetectable when they gain access to your computer. However, as soon as these Trojans start to infect other files, they expose themselves. Similarly, the variant that attacks by mimicking computer system files are also detected by reputable antivirus software as soon as they commence their destructive activity.

There are some types of viruses, who because of their mode of action may escape detection for long periods of time. Complete system scans and regular updating of virus definitions ensure that they can also be dealt with by having a good antivirus. Amongst the threats which can be detected by employing this strategy are what may be termed time delayed viruses. They go about their destructive work in a slow but progressive fashion. As a result, these pests sometimes can go undetected for days. A second variant that can be detected by complete system scans is also called the misdirection virus. It attempts to fool antivirus software of its exact location by creating a number of fake copies of itself.

Anti-spyware and anti-malware also have their place in your computers armory. These two types of software offers protection from a groups of viruses which interfere with the action of antivirus software, making it easier for other threats to bridge your computers security. Another variant which is also successfully detected and and dealt with by these two types of protective software is called the multi-headed virus. This virus attacks attacks executable and startup files in particular.

Firewalls also need some attention. They are of particular importance in protecting computer servers and systems of large business connected to the internet. One of the older threats, called the Bad Penny virus, is able to rapidly infect a non-protected network. Unfortunately, it is easily kept out by a well setup firewall.

Now we have briefly looked at some of the different flavors of computer viruses we find. There is an easy solution. Always ensure that you computer system has adequate protection in all of the discussed departments from reputable sources.
