Most people do not realize the number of issues the industry faces. Even the best antivirus products can be affected by issues. While some issues are minor and can be fixed quickly, other issues are more serious.
One of https://pceasyblog.org/how-to-disable-and-uninstall-avast the main issues is that virus signatures aren’t enough to shield against the vast majority of threats. It takes antivirus companies several months to release anti-virus updates when new viruses are discovered. This is because they need to wait until their products recognize the virus and then send the virus to be examined.
In the meantime, the virus is likely to spread and it’s likely that dozens or even hundreds of computers will be affected by the new virus. It may also be spread to other networks. To be efficient, anti-virus software has to be able to identify and stop these infections quickly. This means that heuristic or behavior analysers are more effective than signature detection that is simple.
Another problem is that compatibility issues between different antivirus programs is quite common. While the majority antivirus software developers place much emphasis on developing quality products and pay tremendous attention to fixing bugs, the reality is that occasionally multiple antivirus programs can lead to conflicts.
