Many people are unaware of the many problems the industry has to face. Even the top antivirus software can encounter issues. Some are minor and easily be addressed, while others are more severe.

One of the most significant issues is that antivirus signature protection does not cover a wide variety of threats. It takes antivirus companies a long time to release anti-virus updates when new viruses are discovered. They have to wait until the virus is identified by their products and then sent to be analysed.

The virus could spread, and dozens, if not hundreds of computers are likely to be infected. It may also be spread to other networks. To be efficient, anti-virus software has be able to recognize and eliminate these infections quickly. This means that behaviour blockers or heuristic analyser are more effective than signature detection.

Another problem is that incompatibility between various antivirus programs is very common. While the majority of antivirus software makers are focused on creating high-quality products and removing bugs, it is true that multiple antivirus programs can sometimes create conflicts.
