More Than A Virus, Common Malware to Watch Out For…
The term “virus” is often used to describe many different types of infection a computer might have. Virus, when used as a blanket term, can describe any number of potential computer programs. What these programs have in common are they are typically designed to cause damage, steal data, or spread across the network.
Malware describes software designed to act maliciously on a personal computer. The name ‘malware’ is a shorthand for ‘malicious software’ and describes exactly what it is. A computer virus is a single type of malware that can cause harm to your PC, but it is only one of many.
Adware
Short for advertising-supported software, adware is a type of malware that delivers advertisements to your computer. These advertisements are often intrusive, irritating, and often designed to trick you into clicking something you don’t want. A common example of malware is pop-up ads that appear on many websites and mobile applications.
Adware often comes bundled with “free” versions of software that uses these intrusive advertising to make up costs. Commonly it is installed without the user’s knowledge and made excessively difficult to remove.
Spyware
Spyware is designed to spy on the user’s activity without their knowledge or consent. Often installed in the background, spyware can collect keyboard input, harvest data from the computer, monitor web activity and more.
Spyware typically requires installation to the computer. This is commonly done by tricking users into installing spyware themselves instead of the software or application that they thought they were getting. Victims of spyware are often be completely unaware of its presence until the data stolen is acted on in the form of fraudulent bank transactions or stolen online accounts.
Virus
In technical terms a computer virus is a form of malware that is installed inadvertently, causing damage to the user. A typical virus may install a keylogger to capture passwords, logins, and bank information from the keyboard. It might steal data, interrupt programs, and cause the computer to crash.
Modern virus programs commonly use your computers processing power and internet bandwidth to perform tasks remotely for hackers. The first sign of this can be when the computer sounds like it is doing a lot of work when no programs should be running. A computer virus is often spread through installing unknown software or downloading attachments that contain more than they seem.
Ransomware
A particularly malicious variety of malware, known as ransomware, prevents the user from accessing their own files until a ransom is paid. Files within the system are often encrypted with a password that won’t be revealed to the user until the full ransom is paid.
Instead of accessing the computer as normal, the user is presented with a screen which details the contact and payment information required to access their data again.
Ransomware is typically downloaded through malicious file attachments, email, or a vulnerability in the computer system.
Worm
Among the most common type of malware today is the computer worm. Worms spread across computer networks by exploiting vulnerabilities within the operating system. Often these programs cause harm to their host networks by consuming large amounts of network bandwidth, overloading computers, and using up all the available resources.
One of the key differences between worms and a regular virus is its ability to make copies of itself and spread independently. A virus must rely on human activity to run a program or open a malicious attachment; worms can simply spread over the network without human intervention.
Should You Repair, Upgrade, or Replace Your Computer? Like many valuable things we buy, new computers suffer from wear and tear over time. Our computers are particularly vulnerable as we have placed more and more demands on them every year. New machines have gotten faster, quieter, more reliable, and more capable over time. At the same time our own computers have begun to slow and sometimes even stop performing altogether.
There are many ways to address the problem of a PC which isn’t quite performing up to the task anymore. Whether frustratingly slow or no longer working; we are happy to take a look. When you bring your computer to us we will diagnose the condition and find a solution that works for you. Often times the simplest solution works best. A complex problem sometimes only needs a simple repair to get your home computer up and running like new again. Whether a small replacement part, loose wire, or bad connection; we will find and fix the problem to give your familiar, home machine a new lease of life.
Many computers come to us running slowly, taking a long time to start up, or freezing when trying to load files and programs. Often owners have reached breaking point and become convinced the machine is fit for only the scrap heap. In many cases, the problem can be pinpointed to a bottleneck in the system. A single, seemingly trivial, part can be holding up the entire system. Amazingly, upgrading just that one component can make the whole machine run like new again.
Adding memory can provide extra space for programs to run faster. Adding an updated, faster hard drive can allow files to be retrieved without delay. In both cases, a low-cost single component can provide a cost-effective solution that makes an old machine like new again.
In some cases, computers succumb to more major faults. A critical part, difficult to replace, may stop working altogether. A failure of the motherboard for example, the backbone that all other components connect to can be expensive, if not impossible, to fix. Typically, with the fast-paced and ever-changing nature of computing, a motherboard will only house computer parts that were manufactured around a similar time.
A motherboard is almost certain to be incompatible with components built just a couple of years before or after its own design for example. Occasionally even a motherboard failure can be resolved too. In these cases we strive, whenever possible, to find a replacement board of the same generation that will work alongside existing components. The result is a cost-effective solution that keeps cost down by saving replacement parts.
In cases where a like-for-like replacement motherboard is not available, many parts of the computer may have to be replaced at the same time. Often replacement costs in these cases can get close to, or even exceed the cost of buying a new machine.
We would always give advice where it makes sense financially and practically to consider replacing an old machine. Often, in this respect, a home PC can be considered a little like a car. Sometimes a simple, non-expensive, easy to replace component such as the window wiper can fail. While a crucial part to be used for driving; it would be silly to suggest replacing the vehicle once it has worn out.
A window wiper may be low-cost and simple to replace, but if the engine were to wear down or break the solution may not be quite as simple. Attempting to make a 30-year-old car as fast, safe, and reliable as a brand new model generally doesn’t make any financial or practical sense. Sometimes the best course of action to save money and avoid breakdowns is a more up to date vehicle.
In computing, many of the same rules hold true. The best solution in each case is always tailored personally to fit you and your own computer.
