About Anti Virus and Spyware
ANTI VIRUS
What is anti virus and what is its function?
Anti virus are programs whose function is to detect and eliminate viruses and other malicious software (sometimes called malware), part of anti virus functioned to eliminated malware, is called antimalware program/application.
How does it work?
An anti virus code compares each file with a database of codes of known viruses, so it is important to regularly update it so that a new virus is not detected.
Characters that should have on anti virus:
Detection and disinfection capabilities: It is logical. An anti virus is better the more virus is able to detect and remove. It is more dangerous to think that there is no doubt that having the virus, so there is nothing worse than feeling safe with a virus or outdated offering few guarantees.
Heuristics: The ability to detect unknown viruses by means of surveys of the system in search of "symptoms" of classics such as infection dates in odd files, memory resident programs, system settings and so strange.
Speed: Today's hard drives are huge and if we think of corporate intranets and the amount of data to be scanned can be colossal.
Therefore be valued in an anti virus scanning capability quickly.
Update: Every day hundreds of new viruses appear, so a virus is capable of removing a virus is necessary to include the information of the virus and its antidote in the libraries or databases viral.
The ability to upgrade these libraries (especially online) is a key factor.
Service: An infection of a virus can give rise to panic in some cases.
Having a service that is able to use another plus.
Recommendation: There is something that maybe is a key council.
You can not rely on anti virus software.
Each has its limitations and obstacles, so the best way to prevent infection is prevention, and in any case have two anti viruses installed instead of one.
SPYWARE
What is spyware?
Are just one type of micro hidden in others, is a file or application software installed on your computer, generally without the knowledge of the user.
How does it work?
Collects information on the habits of the user's PC and sends this information via Internet to the creator of the spyware. In most cases, is associated with free applications that are downloaded from the Internet, such as mp3 players, free anti virus, etc...
Disadvantages when our computer infected with spyware:
- Indiscriminate use of the CPU of the computer (in some cases, constant), which translates into a sharp decline in the speed of the computer.
- Abuse of the Internet connection, sending and receiving data, and therefore a decrease in the usable bandwidth (Internet slower)
- Use of RAM, which could be reserved for programs that really need (slow computer).
In fact, we ourselves accept the installation of spyware on our computers, installing software and accepting "License Agreements" of them without reading them faster to install these programs. In these "License Agreements", if one stops to read them carefully, we accept the fact that other companies install programs that collect personal information.
So how they transfer their data?
These data can be transmitted from irrelevant:
- Number of connections.
- Duration.
- Operating System ...
Passing through quite relevant:
- Pages viewed.
- Length of stay in them.
- Banners on which it is pressed.
- Downloads made ...
Preventive action to block spyware:
There are several preventative measures you can take to identify spyware and to make decisions based on whether you want to have it on your computer.
- Be selective about what you install on your computer. If there is no reason to trust the company offering the freeware, it must be subjected to greater scrutiny. Visit their website to learn about the people behind the technology and the technology itself.
- Do not click the buttons "Yes, I accept" when you are installing freeware. Instead, read each license agreement carefully and seek the relevant language to the activity of spyware.
- Be careful with programs that display ads on the user interface. Many spyware programs track how you respond to these ads and their presence is identified with a red flag. When you see ads in a user interface of the program, you could be looking for a spyware.
- Use only reliable download sites, some of which now show freeware products that have a spyware component.
- Try to find good antispyware program the clean your computer, if it's already infected by spyware.
