Summary

Viruses that are detected by AVP engine as 'Virus.Sim' are so-called 'safe' viruses. They are generated by the Rosenthal Virus Simulator. Here's how the author of this Virus Simulator describes these viruses:

"These Virus Simulator programs generate safe and sterile, controlled test suites of sample virus programs. Virus Simulator's ability to harmlessly compile and infect with safe viruses, is valuable for demonstrating and evaluating anti-virus security measures without harm or contamination of the system. The infected programs can be used as bait for virus detecting programs to gain practical virus protection experience."

These viruses do not possess any threat as they don't replicate. They can be only used for anti-virus products testing.

Removal

Automatic action

Based on the settings of your F-Secure security product, it will either move the file to the quarantine where it cannot spread or cause harm, or remove it.

Suspect a file is incorrectly detected (a False Positive)?

A False Positive is when a file is incorrectly detected as harmful, usually because its code or behavior resembles known harmful programs. A False Positive will usually be fixed in a subsequent database update without any action needed on your part. If you wish, you may also:

  • Check for the latest database updates

    First check if your F-Secure security program is using the latest detection database updates, then try scanning the file again.

  • Submit a sample

    After checking, if you still believe the file is incorrectly detected, you can submit a sample of it for re-analysis.

    NOTE If the file was moved to quarantine, you need to collect the file from quarantine before you can submit it.

  • Exclude a file from further scanning

    If you are certain that the file is safe and want to continue using it, you can exclude it from further scanning by the F-Secure security product.

    Note You need administrative rights to change the settings.
