Hi,
when I try to scan the PC I find this error message:

Could not start process:

Error: Could not start process.
C:\Programmi\ClamWin\bin\clamscan.exe
File does not exist.

What does it means? Is my PC protect by viruses or not? What can I do?

Thanks

please do not cross-post I removed your second message and will reply here.

The error message says that file "C:\Programmi\ClamWin\bin\clamscan.exe" does not exist.

do a search for clamscan.exe and freshclam.exe on your c: drive and specify correct path in clamiwn settings-file locations
