Most people know that antivirus software is crucial to the protection of their computer However, few are aware of the magnitude the industry has to deal with. Even the best antivirus software can be affected by issues. While some are minor and can be fixed quickly, some are more serious.
One of the major issues is that virus-signature protection doesn’t cover a broad range of threats. It takes antivirus companies an extended time to release antivirus updates after new viruses are discovered. They have to wait until the virus is detected by their products and then sent to be studied.
In the meantime, the virus is likely to spread, and it’s highly likely that dozens or hundreds of computers will be affected by the new virus. It could also be spread to other networks. Anti-virus software must be able to quickly identify and block these infections. This means that heuristic, or behaviour analysis tools are more effective than signature detection that is simple.
Incompatibility is another issue. While the majority of antivirus software makers focus on creating quality products and removing bugs it is true that multiple antivirus programs may sometimes create conflicts.
