Virus Types

Written by Eric in Uncategorized

People are always asking me what are the different types of malicious software that are attacking their computers, what are their names and what do they do. 

Malware, short for malicious software, is software designed to infiltrate a computer system without the owner’s informed consent. Malware includes computer viruses, worms, trojan horses, spyware, dishonest adware, crimeware, most rootkits, and other malicious and unwanted software. Malware is not the same as defective software that has a legitimate purpose but contains harmful bugs.

Adware is any software package which automatically plays, displays, or downloads advertisements to a computer after the software is installed on it or while the application is being used. Some types of adware are also spyware and can be classified as privacy-invasive software

A computer worm is a self-replicating Malware computer program. It uses a computer network to send copies of itself to other computers and it may do so without any user intervention.  Unlike a virus, it does not need to attach itself to an existing program. Worms almost always cause at least some harm to the network, if only by consuming bandwidth, whereas viruses almost always corrupt or modify files on a targeted computer.

A Trojan, sometimes referred to as a Trojan horse, is non-self-replicating malware that appears to perform a desirable function for the user but instead facilitates unauthorized access to the user’s computer system. Trojan horses are designed to allow a hacker remote access to a target computer system. Once a Trojan horse has been installed on a target computer system, it is possible for a hacker to access it remotely and perform various operations.

A rootkit is a software program or coordinated set of programs designed to gain control over a computer system or network of computing systems without being detected. In virtually all cases, the purpose and motive being to perform any manner of malign act upon a host computing system.

Should I repair or replace my old computer?

When shopping for a desktop /laptop you usually have 3 levels to choose from: Basic entry level, Midline level and High end. If you use your computer every day I never recommend a low end computer.
So many people when thinking about getting a new computer have the impression that, “All I do on a computer is go online, read/send emails, look at my photo’s and type” so the cheapest one will be all I need. The fact however is, NASA and the CIA only employ so many people and that’s all 90% of computer users are doing with their computers.

Software and websites are being upgraded everyday, they are all becoming more and more interactive and memory intensive. The low end computer that barley has enough power to run today’s apps will definitely be out dated a lot faster than if you just spent a few extra dollars upfront. As well if you are using a computer every day chances are very good that you will not make it through the first 12 months without some kind of hardware issue with that dirt cheap low end computer.
If you are a laptop user with a mid level system, expect about a 2 – 4 year life expectancy. I always recommend to clients this bit of advice:

New laptops are around $700 (Mid level laptop)
New desktops are around the same price
A tower that is 4-5 years old, I wouldn’t spend more than $175 to repair.
A laptop that is 3-4 years old, I would not put anymore than $175 to repair.
Many people think just buying a new one is the best answer for even cheap repairs, but you have to remember that buying a new computer can have some costs or new problems that are unexpected.

•Wireless router may need to be configured
•Printer may not install correctly
•Make sure you have all of your software discs
•Make sure all of your data is backed up
•Make sure your camera software will work on the new computer
•You may need to buy a new mouse and keyboard
•That old scanner may not work
•Some old features on the old computer will not be there with the new computer (Briefcase)
•Expect to have a learning curve if you have never used “Vista”. Windows 7 looks and acts nothing like Windows XP.
•Office 2007 is a learning curve in itself. If you opt to buy it, be prepared to play around for awhile if you want to use the extra features out of “new, save, print”.
As you can see, buying a new computer sometimes isn’t worth it….with the extra costs and time, it may be costly, time consuming and frustrating. If you ever have questions, feel free to contact us and we can try to help.
