Summary
Win32.Crypto is an interesting virus from technical point of view, but it's not spreading in the wild and thus not a cause of concern for the end users.
Crypto infects EXE and DLL files and spreads when these are exchanged between machines.
The most interesting part of the virus is that it encrypts data on the hard drive with real-time on-the-fly encryption. So, if you remove the virus, your data is left encrypted. Encryption is done with Microsoft's CryptoAPI.
Removal
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.
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 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.
