It is extremely likely that an emerging virus or Trojan will infect dozens or even hundreds of computers, or thousands. This is particularly true for network worms. It is therefore important that antivirus software providers are able to issue updates quickly and efficiently to stop these computer-related pests from becoming widespread.
Unfortunately, a number of AV programs are plagued by a number of serious issues that limit their effectiveness. If you’re using any of these programs it is important to be aware of these issues so you can take the necessary steps to protect yourself.
The first problem is that a majority of antivirus programs are unable to detect all Trojans and viruses. This is a direct consequence of the fact that hackers and virus writers are constantly creating new types of malware. Anti-virus software is not able to guarantee 100% security.
A common software issue may cause symptoms that look virus-related. Therefore, it is essential to be aware of the more common causes of problems before suspecting that your system has been infected by viruses. Some malware could display pornographic images in the screen or even news articles. Another sign is a screen that displays ads for websites that you haven’t visited.
