Code that's intended to damage a computer or steal information. The technical name for a virus, also known as malware (short for malicious software.)
Vandals are a new breed of malicious code that cannot be efficiently controlled by conventional antivirus software alone. In contrast to viruses that require a user to execute a program in order to cause damage, vandals are auto-executable applications.
Malicious code can take the form of:
* Java Applets
* ActiveX Controls
* Scripting languages
* Browser plug-ins
* Pushed content
Once inside your network or workstation malicious code can enter network drives and propagate. They can also cause network and mail server overload by sending email messages, stealing data and passwords, deleting document files, email files or passwords, and even re-formatting hard drives.
eSafe protects your network from malicious code at the first point of entry into your network: the Internet gateway.
How invented the first antivirus software and when was it written?
Although there is some debate about who can be credited with the first anti-virus software, the most popular opinion is that a man named Bernt Fix developed the first anti-virus package back in 1987 to stop the Vienna virus. Just three years later, 19 different products were developed for similar purposes, including well known McAfee and Norton AntiVirus.
What is the difference between spyware and free ware?
Spyware is a malicious software that aids in gathering information about a person or organization without their knowledge. Spyware can get in a computer as a software virus or as the result of installing a new program.
Freeware, on the other hand, is derived from "free" + "software" which means this software is available for use at no cost. They are created by volunteers and distributed for free.

What do you use to eliminate the possibility of getting a virus?
There are a few advices that can help you to decrease a chance of getting a virus:
1. Don't visit unsafe sites. To best determine what site is dangerous, download a WOT on mywot.com or Mcafee Site Advisor on siteadvisor.com (both are free).
2. Don't download files from sites that you don't trust.
3. Get an antivirus software. I will recommend Avast!, Kaspersky, Norton or Avira because they have a good detection. Some of them have free editions, for example Avast! and Avira, but remember that free edition usually have got less better detection than professional editions.
4. Turn on a pop-up blocker in your browser.
5. Configure your browser's security options. In IE8 you also has got a Protected mode, which will block most viruses and SmartScreen Filter which will check files you're downloading and tell you about phishing sites.
6. Don't use IE6. It's not safe and you will soon get viruses, adware, spyware or Trojan horses. Download IE7, IE8 or Mozilla Firefox instead.
Are online virus scans necessary?
Online Virus Scans are unnecessary and unsafe! An online Virus Scan is giving an outside company access to your personal data, which is likely a virus itself! Please only download and install Virus Protection Software from a reputable company!
Which computer system is better Acer or Lenovo?
I would have to say HP works the best because they last longer and they are nicer and if you buy HP used you can get a good deal, but you have to be careful were you buy. My sisters and I have HPs and they are nice.
Both are ok, but your best bet on buying any computer is buying from a smaller company. They generally give the best customer service as well as a more sturdy and higher quality computer.

What are the reasons for the blue screen of death?
IF you mean you want to fix it the first thing to look at is your memory. right click on task bar and click task manager and goto the performance tab and look at your memory. Usually its the memory that is the problem. Dont let the green bars go near the top like between 95-100% that will cause windows tyou o cut everything off. If that doesn't happen your memory stick with melt or explode. you can buy memory sticks to fix it but check your memory often to make sure its not near 100% ifon windows vista of 7 open the CPU and ram (aka memory) so you can check on it. If its near 100% close some windows.
Second reason corrupt and programs
some important files might be corrupt so if you open and application that uses those files the blue screen might happen to you. Best thing to stop corrupt files it to defrag it(putting files that are fallen appart together)use windows defragmenter or downlaod a defragging rpogram like defraggler by piriform.
Applications some applications require drivers that are not on your PC sometimes faliure to have these drivers will cause blue screen of death so check your drivers often.
3rd reason registery problems
your registry is like an index you downlaod a file it make a registry files so when you search up a files it searching your reisted files. Any changes might not be changed so running something that requires a file that has not been registed automatically by windows or moved around and the new location of the file is not changed it the registery. Downlaod a registery fixing program like rose city registy fixer or ccleaner (includes a registry function too)
FIXing your registery might be helpful like if you delete a file registery it can save hard drive space.
Answer
An illegal download is a download that conflicts with the license. What I mean by this is if someone let's say makes a song and they make a license that states any sharing must be authorized by him or her. Then this means that anyone who shares it must ask the creator before they share the song and anyone who receives thesong can only view it. The problem is that people don't know if there is a license to obey. Sometimes people download songs from websites and then share them. Today record producers are suing many people for copyright enfringment. My golden rule is to never download songs or other media from websites. The problem is that there are so many websites and many of the media is malware infected. Even free popular media sharing programs like limewire are infected by malware.
Answer
an illegal download is where something such as a song is put on the internet without the composers consent. Then someone downloads the music and it is illegal.
What can a Trojan virus do to your computer?

More Information:
A computer virus is a computer program that can copy itself and infect a computer without the permission or knowledge of the owner. The term "virus" is also commonly but erroneously used to refer to other types of malware, adware and spyware programs that do not have the reproductive ability. A true virus can only spread from one computer to another (in some form of executable code) when its host is taken to the target computer; for instance because a user sent it over a network or the Internet, or carried it on a removable medium such as a floppy disk, CD, DVD, or USB drive. Viruses can increase their chances of spreading to other computers by infecting files on a network file system or a file system that is accessed by another computer.
The term "computer virus" is sometimes used as a catch-all phrase to include all types of malware. Malware includes computer viruses, worms, Trojan horses, most rootkits, spyware, dishonest adware, crimeware and other malicious and unwanted software), including true viruses. Viruses are sometimes confused with computer worms and Trojan horses, which are technically different. A worm can exploit security vulnerabilities to spread itself to other computers without needing to be transferred as part of a host, and a Trojan horse is a program that appears harmless but has a hidden agenda. Worms and Trojans, like viruses, may cause harm to either a computer system's hosted data, functional performance, or networking throughput, when they are executed. Some viruses and other malware have symptoms noticeable to the computer user, but many are surreptitious.
Most personal computers are now connected to the Internet and to local area networks, facilitating the spread of malicious code. Today's viruses may also take advantage of network services such as the World Wide Web, e-mail, Instant Messaging and file sharing systems to spread.

Can a person with a virus be cured?
With the right medicine if you mean a biological virus. But biological viruses cannot always be cured.
If you mean a computer virus, then you need antivirus software. Or if you know what you are doing, you can boot into console mode and delete or replace the infected files there, particularly if the AV program cannot find it.
How do you delete the desktop.ini virus?
Desktop.ini is a Windows XP system file that stores information about customized folders. If you have customized the display of a folder in any way, such as changing its icon or manner of display, Windows has saved those settings in a desktop.ini file. In the following screenshot, I have right-clicked on a folder and am about to customize it. Fig. 1 - Customizing a folder, which results in a desktop.ini file.
Since Desktop.ini is a Windows system file, you are probably seeing it because you have set Explorer to display hidden/system files. By reversing this setting, you can get rid of Desktop.ini. # In any Windows Explorer window, click Tools → Folder Options… # Click on the View tab. # Check off the radio button next to "Do not show hidden files and folders". # Put a check in the box next to "Hide protected operating system files (recommended)". # Click OK. Here is a picture of the settings I have just described: Fig. 2 - Changing Explorer's "View" settings in order to hide Desktop.ini.
Once you have made these changes, Desktop.ini should be out of sight and out of mind. Here is a screen shot of the same folder from Figure 1. It's still customized, but Desktop.ini is nowhere to be seen.
If you keep getting this error message Error loading DLL file how can you repair this problem?
Typically, reinstalling the program you are trying to run will fix this issue. Always be wary of uninstalling programs that share DLL files. Windows will prompt that the DLL may be used by other programs and removing them may adversely affect other programs that share it. If you are unsure of whether or not a DLL is shared by another program, it is best to leave it.
Some Windows repair tool can help you fix dll errors if you do not know how to resolve them manually.
How can you block pop-ups on a computer?
That has to be done in your browser options. With IE it's in the Internet Options under "Privacy". With Firefox it's in the tool menu, options, content.
Just un-check the block pop-ups box.
Damages caused by a computer virus?
When you get a computer virus your computer may get random pop-ups trying to make you download something or sell something to you. It can also spread itself across your P.C files and make it harder for you to remove it. If you do not have anti-virus software and are an inexperienced online user you should really get an anti-virus or just be more carful of what sites you go on.
If you have a DLL error, first check to see if you deleted the DLL files by checking the recycling bin. If you did, reinstall the program and the error will go away. You can run a virus scan to see if the error is being caused by malware, restore the system to undo any changes that have been made recently, and update your drivers. If these fixes do not help you may have to take the computer to an expert.
