It is extremely likely that an upcoming virus or Trojan will infect hundreds or dozens of computers, and possibly thousands. This is particularly true for network worms. As a result, it is essential that antivirus software vendors are in a position to release updates for protection swiftly and efficiently to stop these computer viruses from spreading.
Unfortunately, a number of AV programs are plagued by a range of serious issues that limit their effectiveness. You should be aware of the risks if you use any of these products so that you can protect yourself.
The first issue is that many antivirus programs are unable to detect all viruses and Trojans. This is because hackers are constantly creating new malware. In the end, not from all anti-virus programs sold off the shelf or on the Web can provide a protection at a level that is close to 100%.
A common software issue could also produce symptoms that appear to be virus-related. It is therefore essential to always look for more common causes of problems prior to assuming that your system has been infected by viruses. Some malware will display pornographic images in the screen or even news articles. Another sign is a screen that displays ads for websites that you haven’t visited.
