What is a Virus and how do I know if I have one ?


There are some obvious symptoms that your computer will develop when it gets infected with a virus. But the first thing I have to mention is that if you had a decent antivirus program installed on your computer you would not have a problem. The virus programs now days are fantastic in crushing any chances of a viruses infecting your computer.

What is a virus?
A virus is a small program that gets into your computer undetected in order to cause havoc. This small software program has either been developed because the author enjoys causing disasters for other people or sometimes for monetary gains. Sometimes a virus is packaged in a file that is called a trojan virus. It is disguised as something else, and once it has gained access to your computer it then releases its intent.

How does a virus get onto my computer?
The people that develop these viruses are constantly finding new ways to infiltrate your computer. When one door shuts, another one opens for them. However the most common ways to get a virus on your computer is through the internet. You might download a file that contains a virus, or maybe you might open an email that has one attached to it. Sometimes even visiting a bad website can infect your computer. The worst one of all, however, is when people download illegal cracked software. This software has usually been taken apart and repackaged with a few extras attached. Maybe you download music or videos from the internet. How do you know you are actually downloading the file you intended to. The file may be named to deceive you, and once you open it you will release the virus.

How do I know if I have a virus or not?
If your computer has been infected with a virus you will quickly see odd signs that it exists. Weird things start happening that you cannot explain. Files might move around, odd error messages may appear, programs might start to fail. For example if your virus scanner program stops working then it could have been disabled by a virus. With all this action taking place in the background your computer will also start to run slow and seem like it is busy all the time.
When browsing the internet you might find that you will not able to visits the pages that you choose. You will be redirected to different websites. You computer might also be sending emails to everyone in your contact list without you knowing.

What can a virus do to my computer hardware components?
People think that a virus simply attacks the file systems of your computer, however this is not true. Some viruses are designed to damaged computer hardware components until they are ruined completely.
Many people will argue that a virus only infects software, however all hardware is controlled by various types of software. Infact the entire computer is controlled by BIOS which is software. BIOS controls the temperature of the motherboard. What if a viruses only purpose was to change the temperature control on your motherboard. The motherboard would overheat and fry itself.
In the old days viruses used to be developed to set the read speed of a floppy disk drive to speeds beyond its capability. The Floppy disk drive would overheat and fry from being overworked. Now days Windows Vista has a service called Superfetch that searches your hard drive, finds out what you use the most, and makes it available for you.. If you made a virus to control Superfetch, we could have a serious problem. Most Vista users already have Superfetch disabled on their computer. A virus could enable it, tell it all files are important, keep it searching non stop, and fry your hard drive that way. Now I can here someone saying "yeah right, not with all the security we have around today". Well you should never underestimate these guys who develop viruses. They can work around anything.

What should I do if I get a virus?
If you suspect that your computer has a virus, scan your computer asap with an antivirus program. If you do not have one or yours is not working, download another one, or get a free scan using the free online virus scanners, such as :-
Symantec Security Check :-
http://security.norton.com/sscv6/WelcomePage.asp
or
Kaspersky lab :-
http://www.kaspersky.com/scanforvirus

There is no guarantee that these free scanners will cure your computer but they might just confirm the fact that you actually have a virus.
If you find viruses but cannot remove them you will need to take your computer to a professional before you lose everything. Another option is to format your computer which means you loose all the files on it and re-install a fresh copy of the operating system. You can backup your files first, but please be aware that they might be infected with a virus also.
If you have scanned your computer, found viruses, and successfully deleted them, then now is the time to buy a decent program that will stop this from happening again.
Do not continue to use the computer without taking action because the longer you leave it the further the virus can spread.
What file types commonly contain viruses when you download them?
Lets face it, downloading is a dangerous business, especially when you have important files stored on your computer. Any file you download can contain a virus. My rule for downloading is to ask myself "Do I know and trust this website I am about to download from?"

Here are a few examples of common files that could contain viruses :-
EXE FILE: If you download a program or anything that requires an install file then it will be an .exe file. When you press on it to install to your computer you could be releasing a virus.
ZIP FILE: People download zip files from the internet that contain any other file type and you will not see it's contents until you open it. A zip file might have an exe file in it.
SCR FILE: Free screensavers for your computer. They always have something bad in them. Sometimes adware or viruses.
DOC FILE: A Microsoft word document can contain macros and small scripts that are viruses.

If you haven't got antivirus software installed on your computer, then refer to : http://support.microsoft.com/kb/49500 for Microsoft recommended antivirus softwares.

REMEMBER : PREVENTION IS BETTER THAN CURE

To do this would require a Bootable CD that contains a minimum of the File Manager program, such as Ultimate Boot CD, BartPE, and the like. Some programs are DOS-based and others are windows based. Or we could use a Linux Live CD, like Knoppix, Ubuntu Live CD and others. In General, the following steps:

  4. Open the file manager program, which is available. If using windows NT, XP or above, make sure the program supports reading NTFS format
  5. Find the file / virus and delete or if still in doubt, just rename from *. exe to *. VRS example. To convince, use the search facility to find files with the same size or nearly the same date. If found , you can rename it.
  6. Back restart the computer and check again

I have a virus and stmanteec antivirus notification keeps popping up on my screen: What can I do??? Help Scan type: Auto-Protect Scan Event: Threat Found! Threat: Trojan.Zlob File: ...


If you have a virus you can not delete or if your system will not boot up correctly and you suspect a virus is the problem, a recommended solution is to start your computer in safe mode and run a virus scan. By running your computer in safe mode, non-essential processes do not start and non-core components are disabled. In other words, only the minimum necessary programs will load. Tough to remove viruses, spyware and other malware usually have no chance to run and disrupt your system and can more easily be removed.
**To run a virus scan in safe mode, you must have active anti virus software installed on your computer.
To run a virus scan in safe mode, follow these steps:
  1. If your computer is on, shut it down
  2. Power on your computer
  3. Immediately after you power on your computer, repeatedly press the [F8] key (about once per second)
  4. In the Windows Advanced Options Menu screen, use the arrows to select Safe Mode and presss [Enter]
  5. Select your current operating system and press [Enter]
  6. Select the user you would like to login under (if applicable)
  7. When your system finishes booting, click the Start button on your task bar
  8. Move your cursor over All Programs and navigate to your anti virus program

How to keep your computer virus free


Many people that I have helped with computer viruses had recently purchased new computers which have virus protection included in the software bundle. The problem with these virus protection programs is that the updates are only good for the first year. After that, you must pay a fee to continue to get virus updates.

Many consumers don't realize this and after the year is up, do not renew the membership with the anti-virus company, leaving their computer unprotected from incoming viruses.

So, if you purchased a computer over a year ago, be aware of this problem. You will need to pay the yearly fee to maintain your anti-virus updates or get another anti-virus software available on the market.

There are some anti virus programs that are free or low cost. I have found AVG to provide a good quality free anti-virus program for home users. You can access the download at http://free.avg.com/us-en/download-avg-anti-virus-free.

Also, remember to be aware of emails from senders that you are not familiar with. Also be very careful about opening attachments on any emails. Be sure you know who sent them to you. Even then, if your not sure, verify with the sender that they actually sent this attachment to you before opening it. Email attachments are one of the most common ways of spreading viruses.

So, be careful and happy surfing!

Virus Guide: 11 things you should know


What is a computer virus --> Computer viruses are small software programs that are designed to spread from one computer to another and to interfere with computer operation.
A virus might corrupt or delete data on your computer, use your e-mail program to spread itself to other computers, or even erase everything on your hard disk.
Computer viruses are often spread by attachments in e-mail messages or instant messaging messages. That is why it is essential that you never open e-mail attachments unless you know who it's from and you are expecting it.
Viruses can be disguised as attachments of funny images, greeting cards, or audio and video files.
Computer viruses also spread through downloads on the Internet. They can be hidden in illicit software or other files or programs you might download.
To help avoid computer viruses, it's essential that you keep your computer current with the latest updates and antivirus tools, stay informed about recent threats, run your computer as a standard user (not as administrator), and that you follow a few basic rules when you surf the Internet, download files, and open attachments.
Once a virus is on your computer, its type or the method it used to get there is not as important as removing it and preventing further infection.
