Welcome to BC kc_renji

Have your performed any other scans and if so, are they finding any infection?

NAV has the ability to detect unknown viruses of various types using heuristic algorithms known as Bloodhound. This technology uses an expert system to analyze the cataloged behaviors and assess the likelihood of viral infection. Bloodhound is not the name of a virus, but a message displayed by NAV when it thinks it may have found a new virus. According to Symantec, Bloodhound detects up to 80% of new and unknown executable viruses, and 90% of new and unknown macro viruses.

Heuristic analysis is the ability of an anti-virus program to detect new viruses before the vendor can get samples and update the program's definitions for detection. Heuristics uses non-specific detection methods to find new or unknown malware which allows the anti-virus to detect and stop if before doing any harm to your system. The techniques involves inspecting the code in a file to see if it contains virus-like characteristics. If the number of these characteristics/instructions exceeds a pre-defined threshold, the file is flagged as a possible virus.

The disadvantage to using heuristics is that it is not as reliable as signature-based detection (blacklisting) and can potentially increase the chances that a non-malicious program is flagged as malicious. With heuristics, there is always a potential risk for a "False Positive" if virus detection technology (AutoProtect Settings) are set to High for Bloodhound and the heuristic analysis flags a file as suspicious or infected that contains no malware. You may want to Reset Bloodhound to default settings and try scanning again.
