There are currently many anti viruses on the market but that does not mean that they are all good. It is now becoming hard to determine which one will give you the best computer security. This is not good news for many people who believe in downloading free antivirus software from the internet since many of them are not good for computer security.

It is therefore good, to have in mind some of the most important features of what a good antivirus can offer and these may include the following;

Registry monitoring. The registry stores a record of all programs which are installed on your computer. Some malicious programs may copy themselves to the registry and then to your operating system which may lead you to lose everything on your computer. Therefore, an antivirus which monitors the registry will be a better one

Password protected setting. A good antivirus should ideally have settings which are password protected, there are some computer virus which copy their codes on anti viruses especially those with old definition updates. Password setting will help you against such threats.

Block web content. The best antivirus software should have an option to allow or block web content which you may not need. This will give you an opportunity to deny sites which may be dangerous from downloading on your computer. It will even give you an opportunity to set your security setting to the levels you may want.

Other features of a good antivirus include:
Real time scanning
Suspicious application detection
Cyber crime blocker and
Good firewall

If you are like most people, you often receive emails forwarded by well-meaning relatives, and other associates that warn you about the latest virus threat, and urging you to send the warning to as many other people as possible. These warnings are nearly always false, and play on the fact that many people are afraid of something happening to their computer, coupled with a lack of knowledge of what viruses really do. These false warnings spread like wildfire because we all want to be helpful and warn our own friends before something terrible happens to them!

This article will reveal a few simple things to look for to help you determine if a warning you receive in email is real or is a hoax. Hint: They are nearly always a hoax!

Hoax virus emails share a number of common themes. By looking for these attributes you can quickly determine the validity of the email. Below is a copy of an actual email that I recently received:

This virus will be received from someone who has your e-mail address in his/her contact list. This is the reason why you need to send this e-mail to all your contacts. It is better to receive this message 25 times than to receive the virus and open it.

If you receive a mail called' POSTCARD,' even though sent to you by a friend, do not open it! Shut down your computer immediately. This is the worst virus announced by CNN. It has been classified by Microsoft as the most destructive virus ever. This virus was discovered by McAfee yesterday, and there is no repair yet for this kind of virus. This virus simply destroys the Zero Sector of the Hard Disc, where the vital information is kept.
