How are most viruses spread from computer to computer?
Computer viruses usually spread in one of three ways: from removable media; from downloads off the Internet; and from e-mail attachments. Although the Internet gets a bad rap as a source of viruses, you're no more likely to contract a virus from the Web than you are from packaged software.
If you want to keep risks to a minimum, then you should buy a good anti-virus software. I recommend you a nice one that is Kaspersky Anti-Virus 7.0. You can understand why it can keep risks to a minimum from its features and function.

What are the names of famous antivirus?
There are many antivirus software are available in market to protect your system from virus attack or malicious threats.
List of antivirus software are given below:-
What is the punishment if you are caught hacking into another computer?
Like any crime it depends on the country in question. Though with hacking you may be subjected to double the punishment. For example, you hack the US government but live in Ireland. Then Ireland will probably punish you but you can also be certain that the US government is going to want to extradite you for punishment there also. Some countries are very strict on hacking while others will protect their hackers - which has led to many rumours and conspiracy theories but that's a different question altogether.
Other factors will also be taking into account, such as was it just some guy sitting in his bedroom doing it so he could brag to his mates, or was it somebody trying to rob a bank or hack FBI for secret documents. The punishment for accessing United States government files is 7 years in federal prison and fines and for deleting these files 10 years in prison and fines. These fines can be in the millions.
it is not a virus but a worm, if you have the proper anti virus software, you will be just fine!!!

Risks of not having an Antivirus software?
the danger of not having a good password is if someone knows guesses your password correct the could hack you and change your password. so make a password no one will guess but also one that you will remember!
They aren't viruses.
They are indexes of certain folders. Their presence allows the computer to know more quickly and efficiently what the content of any given folder is.
There is no point in removing them because they will be created soon after you delete them.
What are some examples of an email virus?
An email virus is usually found inside of a link that is attatched to an email that may look urgent, or from royalty of a distant country. When these links are opened a virus is then transferred into the computer.
Why do you get pop up ads with blocker turned on?
The reason why some people are getting pop-ups of advertisements for insurance and prizes even though a pop-up blocker is installed is that the settings on the blocker may need to be setup correctly. Try going to the options tab in the software and check to make sure that block all ads is checked off.
Is PC Cillin a good virus software?
PC Cillin is a good antivirus software but it still has to be updated a bit to catch up with other antivirus softwares. It is missing a few features that can be found in more recent antivirus software packages.
Does the website jump start give you a virus?
well I'm on jump start and I've got trend micro titanium virus software and it hasn't given me any otherwise my virus software would of picked it up and zapped it away!
so i say that jump start is a virus free site!
What are virus factories called?
Virus factories are commonly referred to as "viral factories" or "viral replication centers." These are specialized cellular compartments where viruses replicate and assemble new viral particles. They often exploit host cellular machinery and resources to facilitate the production of new viruses, ultimately leading to their release from the infected cell.
What is a firewall and why is it necessary?
The main reason why we every computer needs a firewall is that as it is a software or a hardware where hardware is found in routers and software are found in Computer. When you have a firewall installed in your Computer would be protected from unwanted websites and hackers. It monitors the incoming and outgoing networks and block the unwanted and malicious networks to access your PC. So every computer needs to be shielded with a firewall. Get them to always block unauthorized network users. This is the reason why a firewall is necessary software or hardware program.
How can you get all your viruses off your computer?
Well it depends which one or more viruses have infected your computer. Most viruses can be removed without a hitch using a popular antivirus software like AVG. First run a complete scan of your entire computer. Most people have about a hundred thousands files stored on their computer. Therefore, the scan will most likely take about two hours to complete so don't get impatient or worry. After the scan is completed AVG will display the files that they have found to be infected and the name of the virus or other malware. Do what AVG tells you to and if it says restart your computer don't wait do it. Any questions post on my message board.
Which antivirus Software without Internet Connection?
yes obviously you can install anti virus without Internet connection with the help of previously downloaded software either from pen drive, CD, DVD or from any drive of your computer which contains the required software.
But to make it updated with latest definitions (that is able to detect and cure the spam attacks, various virus attacks from the Internet) you must have Internet connection to update your anti virus so that it can effectively detect any possible threat which can be harmful to your computer/laptop.
thanks in advance !!! cheers
What are viruses and spy ware?
Very often spy software is confused with spyware - let's clear up the difference between them.
Spyware is also known as adware, Trojans, viruses. Spyware moves into computer without user permission and knowing at all. After spyware is gathering information about computer users without their knowledge. Spyware periodically sends the gathering information about your interests, often visited websites, personal information and so on to spyware creators. This information is sold to marketing companies and other interested parties. This is NOT that our spy software is doing.
Spy software or computer monitoring software monitors and records everything a user does on a computer but installed directly by its purchaser wish. Spy software can record every action that a user is doing on a computer - but nobody except the purchaser of the software see the report about these actions. This software can be absolutely invisible and nobody can detect it or contrary show to a monitored user a splash warning.
You should always update your antivirus software?
Because people are making new viruses to damage computers. I am pretty sure that ever minute 10 new viruses are made. Every second Tuesday of every month Microsoft creates patches for Windows.It is commonly called Patch Tuesday. Viruses made in this day are called zeo-day viruses. its best to update early
How do you remove Trojan virus form the computet?
1. Download and run firefox to protect your computer from future spyware attacks and pop ups which are coming in through internet explorer (Trojan downloaders, win32 ).Browser attacks aren't easy to spot because they piggyback on legitimate traffic that doesn't exhibit many obvious warning signs . 2. Run the vundo and combo fix 3. Run Malwarebytes Anti-Malware
4. Run the anti spyware remove programs spybot
5. Run a complete scan with free curing utility Dr.Web CureIt!
What is the difference between com files and exe files?
There's not much difference to the normal user. However, to those more concerned with how it works, there are some differences.
A COM file is self-contained and cannot exceed 64KB in size because the stack, data, and code must all fit within 64KB. EXE files have no limiting size and have more header information.
The main difference is how they are loaded. When a COM file is loaded by DOS, it is loaded into low memory. EXE files separated where the CONST is loaded low and DATA is loaded high.
Also, if you have both, say EXAMPLE.COM and EXAMPLE.EXE, in the same directory and try to execute without specifing the extention, the COM will load first.
How does dust and dirt harm computers?
Mostly it builds up on the fans and prevents the system from cooling and will lead to shut downs or unpredictable behavior. Using "dust off" or any other compressed air can you can blow the dust out of all of the fans including any fans on the video card if there is one. There are several fans in a normal computer including,
CPU fan mounted on the actual CPU
case fans mounted on the case (could be severel here too)
video card fans are mounted on the video card itself and can be hard to reach(not all video cards have fans mostly just the top end cards)
Also dust can acumulate on your CD roms optics and will prevent the reading of CD's, any standard CD ROM drive cleaner will work to clean it or you can use a que tip with rubbing alcohol to clean it directly.
What is the most common way to get a virus?
1. E-mail attachment.
2. Lack of firewall on an insecure network.
3. Malicious Web pages.
4. Co-installed with other legitimate but contaminated software.
5. Sometimes products like digital picture frames, MP3 players, flash drives, etc., are pre-infected at point of manufacture.
When a computer system becomes infected with spyware it will be able to monitor and watch the activities of the computer user and record this information. This information relates to aspects such as websites surfed, personal information and web browsing habits.
Spyware can also do more than just monitor activities and take information in that it posesses the ability to cause browser redirecting, can make changes to web security settings, force frequent pop ups to appear and it can also reduce both internet speeds and PC performance.
Anti spyware software has always been the best remedy for removing spyware infections and ensuring that your signature database is constantly updated is critical.
What is a List of computer viruses with their functions?
Computer Virus is a kind of malicious software written intentionally to enter a computer without the user's permission or knowledge, with an ability to replicate itself, thus continuing to spread. Some viruses do little but replicate others can cause severe harm or adversely effect program and performance of the system. A virus should never be assumed harmless and left on a system. Most common types of viruses are mentioned below:
Resident Viruses
This type of virus is a permanent which dwells in the RAM memory. From there it can overcome and interrupt all of the operations executed by the system: corrupting files and programs that are opened, closed, copied, renamed etc.
Examples include: Randex, CMJ, Meve, and MrKlunky.
Direct Action Viruses
The main purpose of this virus is to replicate and take action when it is executed. When a specific condition is met, the virus will go into action and infect files in the directory or folder that it is in and in directories that are specified in the AUTOEXEC.BAT file PATH. This batch file is always located in the root directory of the hard disk and carries out certain operations when the computer is booted.
Overwrite Viruses
Virus of this kind is characterized by the fact that it deletes the information contained in the files that it infects, rendering them partially or totally useless once they have been infected.
The only way to clean a file infected by an overwrite virus is to delete the file completely, thus losing the original content.
Examples of this virus include: Way, Trj.Reboot, Trivial.88.D.
Boot Virus
This type of virus affects the boot sector of a floppy or hard disk. This is a crucial part of a disk, in which information on the disk itself is stored together with a program that makes it possible to boot (start) the computer from the disk.
The best way of avoiding boot viruses is to ensure that floppy disks are write-protected and never start your computer with an unknown floppy disk in the disk drive.
Examples of boot viruses include: Polyboot.B, AntiEXE.
Macro Virus
Macro viruses infect files that are created using certain applications or programs that contain macros. These mini-programs make it possible to automate series of operations so that they are performed as a single action, thereby saving the user from having to carry them out one by one.
Examples of macro viruses: Relax, Melissa.A, Bablas, O97M/Y2K.
Directory Virus
Directory viruses change the paths that indicate the location of a file. By executing a program (file with the extension .EXE or .COM) which has been infected by a virus, you are unknowingly running the virus program, while the original file and program have been previously moved by the virus.
Once infected it becomes impossible to locate the original files.
Polymorphic Virus
Polymorphic viruses encrypt or encode themselves in a different way (using different algorithms and encryption keys) every time they infect a system.
This makes it impossible for anti-viruses to find them using string or signature searches (because they are different in each encryption) and also enables them to create a large number of copies of themselves.
Examples include: Elkern, Marburg, Satan Bug, and Tuareg.
File Infectors
This type of virus infects programs or executable files (files with an .EXE or .COM extension). When one of these programs is run, directly or indirectly, the virus is activated, producing the damaging effects it is programmed to carry out. The majority of existing viruses belong to this category, and can be classified depending on the actions that they carry out.
Companion Viruses
Companion viruses can be considered file infector viruses like resident or direct action types. They are known as companion viruses because once they get into the system they "accompany" the other files that already exist. In other words, in order to carry out their infection routines, companion viruses can wait in memory until a program is run (resident viruses) or act immediately by making copies of themselves (direct action viruses).
Some examples include: Stator, Asimov.1539, and Terrax.1069
FAT Virus
The file allocation table or FAT is the part of a disk used to connect information and is a vital part of the normal functioning of the computer.
This type of virus attack can be especially dangerous, by preventing access to certain sections of the disk where important files are stored. Damage caused can result in information losses from individual files or even entire directories.
Worms
A worm is a program very similar to a virus; it has the ability to self-replicate, and can lead to negative effects on your system and most importantly they are detected and eliminated by antiviruses.
Examples of worms include: PSWBugbear.B, Lovgate.F, Trile.C, Sobig.D, Mapson.
Trojans or Trojan Horses
Another unsavory breed of malicious code are Trojans or Trojan horses, which unlike viruses do not reproduce by infecting other files, nor do they self-replicate like worms.
Logic Bombs
They are not considered viruses because they do not replicate. They are not even programs in their own right but rather camouflaged segments of other programs.
Their objective is to destroy data on the computer once certain conditions have been met. Logic bombs go undetected until launched, and the results can be destructive.
Hope i helped!
