If your computer gets infected, with the described virus, change your password and run a virus scan UPDATE 08/05 2008: I’m still getting strange messages from one specific contact. A couple of seconds after the arrival of the message to my computer, (*)’s account has been logged off. last time I got a weird message, I think the link in it was something like “becool.Com” or something like that. Please watch out, and think before you open anything weird or suspicious
By frequently adding and removing software and hardware from the system may make the system more and more sluggish over time. The system may become slow to the point of being annoying. Yet when the system was new it ran perfectly. There are many answers to why this happens. The system may be infected with viruses that are filling up the resources by replicating themselves or there may be Spyware operating in the background. These Spyware can wreck havoc with the system time by delaying the response of the processor to the programs that are running in front. One other possible reason could be that the registry has gotten full of obsolete entries and references that installing programs and hardware make in the registry. These entries are not removed when the programs or hardware are uninstalled. This has to be done manually or with any free Spyware removal tool made for the very purpose.
Use Software, Do Not Delve Into The Registry Manually
It is incorrect to assume that by uninstalling software from the system all the entries in the system pertaining to the software are removed. Nothing can be further from the truth. Many traces or entries of the uninstalled software or Spyware may be left behind in the system registry, either intentionally or unintentionally. These obsolete entries or references in the registry clutter up the system to such an extent that the system may crash and cause tremendous loss of data. A wake up call is the system slowing down and acting erratically. On such signs you should get some free anti-Spyware removal tool in addition to the anti virus software and scan the system for Spyware that may have installed itself on your system. Many anti virus packs come with software but it you do not have any it may do a world of good to get some anti-Spyware. After running the free anti-Spyware removal tool run the registry cleaner any free registry cleaner to remove all instances form the system registry.
Manual cleaning of the registry is very complicated as well as dangerous because if a wrong file is deleted the system may shut down and not boot up again unless the Operating System is reinstalled. It is for this reason that registry cleaners are designed. They do a great job in a few seconds and leave the system running more efficiently and fast. If your system has been run running sluggishly lately. Run a registry cleaner after the anti-Spyware and it will surely be a pleasure to work on the system again.

If you are using Windows 2000 or XP, the process is a bit trickier. First, you <b>…</b>
By definition, a virus is a computer program that is able to copy itself and infect other computers. The first one, according to Wikipedia, was seen almost half a century ago. The Creeper virus was detected in ARPANET, a predecessor of the World Wide Web. This code is compared to their virus dictionaries and if a match is found, the antivirus program attempts to clean the suspicious part, without damaging the original data. Another method of fighting viruses is to monitor computer activity, also known as heuristic analysis. It was using the modem connection to replicate on other PCs and when it achieved its goal, it displayed the following message IM THE CREEPER: CATCH ME IF YOU CAN. Anti virus software is another kind of computer programs that appeared because of the need to disinfect computers from viruses. Reaper was the first of its kind and its aim was the Creeper virus. You can visit Some people said that they might have shared the same creator, but this was never proved.
Since the first antivirus program, viruses and methods to fight them evolved rapidly. Most of the times, the next step in evolution is done by computer viruses and antivirus creators struggle to fight back and invent new ways to clean those pesky bugs. The common approach of antivirus software is to scan files, memory or registries from your computer and detect malicious code. This code is compared to their virus dictionaries and if a match is found, the antivirus program attempts to clean the suspicious part, without damaging the original data. Another method of fighting viruses is to monitor computer activity, also known as heuristic analysis. This includes monitoring memory and ports traffic for any signs of infection. A modern approach is the so called sandbox method. It involves running the suspicious file into a simulated operating system and analyzing the results. No matter the method, if a virus is found, the antivirus first attempts to disinfect the file. If its unsuccessful, or go to the infected file is quarantined (isolated from other programs) or in worst case, deleted.
Its very important to have a reliable antivirus program installed because there can be viruses on a file you download, inside an email attachment or even a website can include some malicious code to infect your PC. Some of the programs that are out there and can do the task are free, but most of them require payment. This code is compared to their virus dictionaries and if a match is found, the antivirus program attempts to clean the suspicious part, without damaging the original data. Reaper was the first of its kind and its aim was the Creeper virus. Another method of fighting viruses is to monitor computer activity, also known as heuristic analysis. Almost all include updates of their viruses database, to make sure your PC is protected to the newest threats. AVG AntiVirus Free, BitDefender Free, Comodo AntiVirus and PC Tools AntiVirus Free Edition are only a couple of the free antivirus programs available on the Internet.

Today, many people rely on computers to do homework, work, and create or store useful information. Therefore, it is important for the information on the computer to be stored and kept properly. It is also extremely important for people on computers to protect their computer from data loss, misuse, and abuse. For example, it is crucial for businesses to keep information they have secure so that hackers can’t access the information. Home users also need to take means to make sure that their credit card numbers are secure when they are participating in online transactions.
A computer security risk is any action that could cause lost of information, software, data, processing incompatibilities, or cause damage to computer hardware, a lot of these are planned to do damage. An intentional breach in computer security is known as a computer crime which is slightly different from a cypercrime. A cybercrime is known as illegal acts based on the internet and is one of the FBI’s top priorities. There are several distinct categories for people that cause cybercrimes, and they are refereed as hacker, cracker, cyberterrorist, cyberextortionist, unethical employee, script kiddie and corporate spy. The term hacker was actually known as a good word but now it has a very negative view. A hacker is defined as someone who accesses a computer or computer network unlawfully. They often claim that they do this to find leaks in the security of a network. The term cracker has never been associated with something positive this refers to someone how intentionally access a computer or computer network for evil reasons. It’s basically an evil hacker.
They access it with the intent of destroying, or stealing information. Both crackers and hackers are very advanced with network skills. A cyberterrorist is someone who uses a computer network or the internet to destroy computers for political reasons. It’s just like a regular terrorist attack because it requires highly skilled individuals, millions of dollars to implement, and years of planning. The term cyperextortionist is someone who uses emails as an offensive force. They would usually send a company a very threatening email stating that they will release some confidential information, exploit a security leak, or launch an attack that will harm a company’s network. They will request a paid amount to not proceed sort of like black mailing in a since. An unethical employee is an employee that illegally accesses their company’s network for numerous reasons. One could be the money they can get from selling top secret information, or some may be bitter and want revenge. A script kiddie is someone who is like a cracker because they may have the intentions of doing harm, but they usually lack the technical skills. They are usually silly teenagers that use prewritten hacking and cracking programs. A corporate spy has extremely high computer and network skills and is hired to break into a specific computer or computer network to steal or delete data and information.
Shady companies hire these type people in a practice known as corporate espionage. They do this to gain an advantage over their competition an illegal practice. Business and home users must do their best to protect or safeguard their computers from security risks. The next part of this article will give some pointers to help protect your computer. However, one must remember that there is no one hundred percent guarantee way to protect your computer so becoming more knowledgeable about them is a must during these days. When you transfer information over a network it has a high security risk compared to information transmitted in a business network because the administrators usually take some extreme measures to help protect against security risks. Over the internet there is no powerful administrator which makes the risk a lot higher. If your not sure if your computer is vulnerable to a computer risk than you can always use some-type of online security service which is a website that checks your computer for email and Internet vulnerabilities. The company will then give some pointers on how to correct these vulnerabilities.
The Computer Emergency Response Team Coordination Center is a place that can do this. The typical network attacks that puts computers at risk includes viruses, worms, spoofing, Trojan horses, and denial of service attacks. Every unprotected computer is vulnerable to a computer virus which is a potentially harming computer program that infects a computer negatively and altering the way the computer operates without the user’s consent. Once the virus is in the computer it can spread throughout infecting other files and potentially damaging the operating system itself. It’s similar to a bacteria virus that infects humans because it gets into the body through small openings and can spread to other parts of the body and can cause some damage. The similarity is, the best way to avoid is preparation. A computer worm is a program that repeatedly copies itself and is very similar to a computer virus. However the difference is that a virus needs o attach itself to an executable file and become a part of it. A computer worm doesn’t need to do that I seems copies to itself and to other networks and eats up a lot of bandwidth. A Trojan Horse named after the famous Greek myth and is used to describe a program that secretly hides and actually looks like a legitimate program but is a fake. A certain action usually triggers the Trojan horse, and unlike viruses and worms they don’t replicate itself. Computer viruses, worms, and Trojan horses are all classifies as malicious-logic programs which are just programs that deliberately harms a computer.
Although these are the common three there are many more variations and it would be almost impossible to list them. You know when a computer is infected by a virus, worm, or Trojan horse if one or more of these acts happen:
- Screen shots of weird messages or pictures appear. - You have less available memory then you expected - Music or sounds plays randomly. - Files get corrupted - Programs are files don’t work properly - Unknown files or programs randomly appear - System properties fluctuate
Computer viruses, worms, and Trojan horses deliver their payload or instructions through four common ways. One, when an individual runs an infected program so if you download a lot of things you should always scan the files before executing, especially executable files. Second, is when an individual runs an infected program. Third, is when an individual bots a computer with an infected drive, so that’s why it’s important to not leave media files in your computer when you shut it down. Fourth is when it connects an unprotected computer to a network. Today, a very common way that people get a computer virus, worm, or Trojan horse is when they open up an infected file through an email attachment. There are literally thousands of computer malicious logic programs and new one comes out by the numbers so that’s why it’s important to keep up to date with new ones that come out each day. Many websites keep track of this.
There is no known method for completely protecting a computer or computer network from computer viruses, worms, and Trojan horses, but people can take several precautions to significantly reduce their chances of being infected by one of those malicious programs. Whenever you start a computer you should have no removable media in he drives. This goes for CD, DVD, and floppy disks. When the computer starts up it tries to execute a bot sector on the drives and even if it’s unsuccessful any given various on the bot sector can infect the computer’s hard disk. If you must start the computer for a particular reason, such as the hard disk fails and you are trying to reformat the drive make sure that the disk is not infected.
