|Virus signature files are corrupted|
The reason for this error is that the virus signature files that were downloaded are corrupted. The reason for this can be a bad connection, a proxy server, not enough disk space and so on. The older virus signature files will be restored.
There is a great chance that this is a temporary issue. Therefore we urge you to try to update the virus signature files again if this error occurs.
If updating the virus signature files through the Updater does not solve the problem, try updating the virus signature files manually. Do the following:
NB: F-PROT Antivirus engine itself will not run after deleting the definition files (Sign.def, Sign2.def, Macro.def). You will probably receive an error like Error:SIGN.DEF not found.
