It is very likely that an upcoming virus or Trojan will infect dozens or hundreds of computers, or even thousands. This is especially true of network worms. Therefore, it is essential that antivirus software providers are able to issue updates quickly and efficiently to prevent these computer pests becoming widespread.
Unfortunately, a number of AV programs are plagued by a variety of major issues that affect their effectiveness. It is essential to be aware the problems if you are using any of these products to ensure that you are protecting yourself.
The first issue is that a majority of antivirus programs are unable to detect all Trojans and viruses. This is because of the fact that hackers and virus writers constantly create new varieties of malware. As a result, far from any anti-virus software available on the Web will provide a protection of even a fraction of 100%.
A common software issue could also produce symptoms that appear virus-related. It is therefore essential to always look for more common causes of problems before suspecting that a system is infected by a virus. Some malware could display pornographic images in the screen, or news articles. Another symptom is a screen that shows ads for sites that you haven’t visited.
