If a new virus or Trojan hits the Internet it is likely that it will infect dozens, hundreds or even thousands of computers is very high. This is especially true of network worms. It is therefore important that antivirus software providers are able to provide updates quickly and efficiently to prevent these computer pests becoming widespread.
Unfortunately, many AV programs are plagued by a variety of major issues that affect their effectiveness. You should be aware of the issues when you use any of these programs so that you can protect yourself.
The first issue is that a lot of antivirus programs aren’t able to detect all Trojans and viruses. This is a direct consequence of the fact that virus writers and hackers are constantly creating new types of malware. Antivirus software isn’t able to guarantee 100% security.
A common software issue can produce symptoms that appear to be virus-related. It is crucial to examine other causes of problems, before you suspect that a computer has been infected with virus. For instance, certain kinds of malware can trigger pop-up windows to appear on the screen, which displays pornographic images or news articles. Another indication is when the screen constantly displays ads for sites that you don’t visit.
