Computer users are often get confused by the various terms used to define security programs. Antivirus is a very common terminology, but the others are quite confusing to many. For example, an antispyware could sound like a word from the outer space to some people if they haven’t heard it ever before. Especially while buying an antivirus software package from some renowned company, they come up with all these options like antivirus, antimalware, antispyware, firewall and it gets difficult to make a choice which one to really buy. As a result, computer users often end up buying unnecessary programs for a much higher price quote.
A virus is a malicious computer program. Programmers who are capable of writing malicious programs are quite genius than the mainstream ones because it takes more precise knowledge on programming to create something which has the capability to bypass the security protocols on a computer and harm the settings or files. However, a virus loads within a computer without acquiring permission from the user. Once a virus infects a PC, it could alter the way of operating the computer leading itself to eventually die; or lose the files stored on it. Either the, both the machine and its user is harmed – that’s what computer viruses are built for. An antivirus program would especially look for a virus, quarantine it or delete it. Signature based scanning is used to locate and delete viruses.
Spywares are malicious software too, but they don’t really harm a computer system. Instead, they intrude into a computer system without the user’s knowledge and steal information from the user; later send it to the designated address – usually the creator of the spyware. The program operates in stealth mode and it is really difficult to know a spyware got installed in a computer system. Without specific spyware programs, removal of one could take very complicated efforts. Instead of signature based methods; spywares used behavioral scanning methods to locate and delete spywares.
Even though the operational capacities and working procedure of both these types of malicious programs are quite different, yet the antivirus and antispyware programs operate in quite a similar way. Both these programs would first scan the computer registry for malicious activities – the registry is one place where every program that operate on a computer has to leave some trace. They scan files stored for plausible threats as well. Most antivirus software these days come with an antispyware these days and vice versa – it’s a complete package so that people don’t need to bother buying each of these separately. All-in-one software saves a lot on the monetary transactions because different individual programs will sum up to a bigger purchase price. But such combined packages offer the convenience of having everything installed on your computer at a relaxing price, and hassle free installation.
Most computers, especially the ones that run Microsoft Windows operating systems are under threat of security attacks. Hence, taking your time to research the best security software options for your computers is certainly one of the best investments you are making.
