The majority of people are aware that antivirus software is crucial to the protection of their computers However, few are aware of the magnitude the industry has to contend with. Even the most effective antivirus programs can be affected by issues. While some issues are minor and can be resolved quickly, other issues are more serious.
One of the major issues is that virus signatures aren’t enough to protect against a large number of threats. Every time new viruses emerge, it takes a while before the antivirus companies are able to develop and release new anti-virus updates. They have to wait until the virus is spotted by their software and then sent to be studied.
In the meantime the virus is likely to spread, and it’s very likely that dozens or even hundreds of computers will be infected by the virus. It could also extend to other networks. To be effective, anti-virus software needs to be able to identify and block such infections very quickly. This means that heuristic, or behaviour analysers are more efficient than simple signature detection.
Incompatibility is another problem. While the vast majority of antivirus software developers put much emphasis on developing quality products and pay a lot of attention to fixing bugs, the reality is that there are times when multiple antivirus programs can create conflicts.
