How to use CAVS command line?
If you look in the C:\PROGRAM FILE\COMODO\COMODO ANTIVIRUS folder, there is an exe called CAVSCONS. This is command line scanner.
Supported switches are
[drive]
[file spec] - * and ? wildcards are supported
/D = Attempt disinfection
/R [filename] = Create report
Example : To scan all powerpoint files on drive D: and create a report called ppoint.txt on the C: drive, the command would be;
cavcons d: *.ppt /R=c:\ppoint.txt
Hope this helps,
