It is not widely known how many problems the industry faces. Even the top antivirus software may have 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 sufficient to guard against a large number of threats. It takes antivirus companies some time to issue anti-virus updates when new viruses are discovered. This is because they need to wait until their products recognize the virus and send it to be analysed.
In the meantime the virus is expected to spread, and it’s quite likely that dozens or even hundreds of computers will be infected by the virus. It may also be spread to other networks. Antivirus software should be able to detect and stop these infections. This means that behavior blocking or heuristic analyser are more effective than signature detection.
Another issue is that the incompatibility of different antivirus programs is a common occurrence. While the majority of antivirus software developers place an focus on developing high-quality products and pay great attention to fixing bugs, the truth is that there are times when multiple antivirus programs can result in conflicts.
