It is extremely likely that an emerging virus or Trojan could infect dozens, hundreds of computers, or even thousands. This is especially true for network worms. It is therefore important that antivirus software providers can release updates quickly and effectively to stop these computer viruses from becoming widespread.
Unfortunately, many AV programs are plagued by a range of major problems that compromise their effectiveness. It is essential to be aware the problems if you are using any of these products so that you can protect yourself.
First the fact that many anti-virus programs can’t detect all viruses and Trojans. This is due to the fact that hackers are constantly creating new malware. Anti-virus software isn’t able to provide 100% protection.
A common software issue may also cause symptoms that look virus-related. It is important to always examine other causes of issues, before you think that a computer has been infected with a virus. For example, some types of malware may cause pop-up windows to appear on the screen that shows pornographic images or news articles. Another symptom is that the screen keeps showing ads for websites you don’t visit.
