MSIL/Cxover.A is a prooof-of-concept virus written in Microsoft .NET's Microsoft Intermediate Language (MSIL) that can affect both PCs using Windows OS with .NET runtime installed and Windows Mobile handheld devices supporting .NET.
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.
Cxover.A infects devices over Microsoft's ActiveSync protocol. If the Cxover.A binary is executed on a Windows Mobile device, it looks for the PC over the ActiveSync connection and copies itself to the PC so that it will start automatically at next boot.
If Cxover.A is executed on a Windows PC it will search for any handled devices connected over ActiveSync and copy itself there.
