Many people are aware that antivirus software is essential for protecting their computers However, few are aware of the amount the industry has to contend with. Even the best antivirus software are susceptible to issues. While some are minor and can be addressed quickly, some are more serious.
One of the major issues is that virus signatures aren’t enough to shield against the vast majority of threats. It takes antivirus companies a long time to release antivirus updates after new viruses are discovered. This is due to the fact that they have to wait until their software detects the virus and then send it in to be analysed.
In the meantime the virus is bound to spread and it’s very likely that dozens or even hundreds of computers will be infected by the virus. It could also spread to other networks. To be effective, anti-virus software needs be able to recognize and block such infections very quickly. This means that heuristic, or behaviour analysis tools are more effective than signature detection that is simple.
Another problem is that incompatibility between various antivirus programs is a common occurrence. While the majority of antivirus software makers focus on creating quality products and eliminating bugs, it is true that a variety of antivirus programs can occasionally create conflicts.
