It is highly likely that the emergence of a new 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 vendors are able to release protection updates swiftly and efficiently to prevent these computer worms from spreading.
Unfortunately, AV programs suffer from many major issues that affect their effectiveness. It is important to be aware of the problems if you are using any of these programs so that you can protect yourself.
The main issue is that a majority of anti-virus programs can’t detect all viruses and Trojans. This is because of the fact that hackers and virus writers are constantly creating new types of malware. Antivirus software isn’t able to guarantee 100% security.
Another issue is that many common software issues can cause symptoms that resemble viruses-related problems. It’s therefore vital that you always look for more common causes of problems before suspecting that your system may be affected by a virus. For example, some types of malware can cause pop-up windows to appear on the screen that antivirus problems displays pornographic images or news articles. Another indication is when the screen keeps showing ads for sites that you don’t visit.
