It is very likely that the emergence of a new virus or Trojan will infect dozens or even hundreds of computers, and possibly thousands. This is especially true of network worms. It is therefore important that antivirus software providers can release updates swiftly and effectively to stop these computer-related pests from becoming widespread.
Unfortunately, AV programs suffer from many major issues that affect their effectiveness. If you’re using any of these products you should be aware of these issues so that you can take steps to protect yourself.
The main issue is that a lot of anti-virus programs simply cannot detect all Trojans and viruses. This is a direct result of the fact that virus writers and hackers constantly create new varieties of malware. As a result, far from any anti-virus software available on the Web can provide a protection in any way that is 100 100%.
Another issue is that many common software problems can create symptoms that resemble virus-related errors. Therefore, it is essential to always check for more typical reasons for problems before deciding that your system is affected by viruses. For example, some types of malware can cause pop-up windows to pop up on your screen, which displays pornographic images or news articles. Another indication is when the screen constantly displays ads for sites that you don’t visit.
