Most people know that antivirus programs are crucial for the security of their computers However, few are aware of the extent the industry has to deal with. Even the best antivirus software are susceptible to issues. While some issues are minor and can be addressed quickly, some are more serious.
One of the main issues is that virus signatures do not provide sufficient to guard against a wide range of threats. It takes antivirus companies several months to release anti-virus updates when new viruses are discovered. This is because they have to wait until their products recognize the virus and then send it in to be analysed.
In the meantime the virus is bound to spread, and it’s quite likely that hundreds or dozens of computers will be infected by the new virus. It may also spread to other networks. To be efficient, anti-virus software must to be able to detect and stop these infections quickly. This means that behaviour blocking or heuristic analysis tools are more effective than simple signature detection.
Another problem is that the incompatibility of different antivirus programs is very common. While the majority of antivirus software makers concentrate on developing high-quality products and removing bugs, it is true that multiple antivirus programs can occasionally create conflicts.
