When a new virus or Trojan is introduced to the Internet, the likelihood that it will be infected by dozens, hundreds or even thousands of computers is very high. This is particularly true for network worms. Therefore, it is crucial that antivirus software providers are in a position to release updates for protection quickly and efficiently to prevent these computer worms from becoming widespread.
Unfortunately, a lot of AV programs are plagued by a range 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 that you can take the necessary steps to protect yourself.
The main issue is that many antivirus programs aren’t able to detect all Trojans and viruses. This is because hackers are constantly creating new malware. Anti-virus software isn’t able to provide 100% security.
A common software issue could also cause symptoms that appear virus-related. It’s essential to be aware of the more common causes of issues before you suspect that your system is affected by a virus. For instance, certain kinds of malware can cause pop-up windows to appear on the screen that displays pornographic images or news articles. Another symptom is a window that displays advertisements for websites that you haven’t visited.
