It is extremely likely that an upcoming virus or Trojan will infect dozens or even hundreds of computers, or even thousands. This is especially true for network worms. As a result, it is important that antivirus software vendors are in a position to release updates for protection swiftly and efficiently to prevent these computer pests from spreading.
Unfortunately, AV programs suffer from many major issues that hinder their effectiveness. If you’re using one of these software it is important to be aware of these problems so that you can take steps to protect yourself.
The first problem is that a majority of anti-virus programs simply cannot detect all viruses and Trojans. This is a direct consequence of the fact that hackers and virus writers constantly create new varieties of malware. In the end, not from any anti-virus program sold on the Web can provide a security of even a fraction of 100 percent.
A common software problem can also produce symptoms go that look virus-related. It is important to always be aware of other causes for problems, before you suspect that your computer is affected by virus. Some malware can display pornographic images on your screen or display news articles. Another indication is when the screen constantly displays ads for websites you do not visit.
