A primitive virus which is rather "buggy", as infected programs are usually not able to replicate, as they are corrupted because of an error. This might be corrected in a later version, though.
If a file contains potentially damaging routines or suspicious code, F-Secure security products will flag it as Suspicious as a precautionary measure.
For more information, see: F-Secure Community Knowledge Base: Automatic actions for viruses also used for suspicious items.
Security programs will sometimes unintentionally identify a clean program or file as malicious if its code or behavior is similar to a known harmful program or file. This is known as a False Alarm or False Positive (FP).
For example, 'tmp.edb' and other '.edb' files stored at the location 'C:\WINDOWS\SoftwareDistribution\DataStore\Logs\' may be unintentionally detected as malicious by various security programs.
In most cases, a False Positive is fixed in a subsequent database release; updating your F-Secure security product to use the latest database is enough to resolve the issue. If you suspect a detected file may be a False Positive, you can check by first updating your F-Secure security product to use the latest detection database updates, then rescanning the suspect file.
After checking, if you believe the file or program is still incorrectly detected, you can submit a sample of it to F-Secure Labs for analysis and correction:
If you are positive that the suspect file is safe and you want to continue using it, you can exclude it from further scanning by the F-Secure security product:

Microsoft provides enterprise-level instructions for excluding files from scanning by antivirus software:
F-Secure security programs include heuristic engines that perform extended file analysis during a system scan in order to identify suspicious, malware-like code or potentially harmful routines. Actual detection names used by the heuristic engines may vary, and include:
Possibly Infected With an Unknown Virus, Saattaa olla tuntemattoman viruksen saastuttama, Possibly a mass mailing worm, Virus-like code found by heuristics, Deepscan:generic.malware, Gen:Heur, Possibly Destructive Program, New or Modified Variant Of, Viruses cannot be disinfected unless they are identified
The suspect file found on the computer system showed malicious/potentially damaging routines or characteristics.
The suspect file contains trojan-like code or behavior.
Possible misdisinfected virus
The suspect document or a workbook may contain an incompletely disinfected virus.
Suspicious Win32 PE
