A lot of investigative tools have been doing this.
Process Hacker, System Explorer, Process Explorer and AnVir Task Manager Free allow you to right-click on a process and submit it to Jotti's virusscan, VirusTotal, or Comodo for analysis.
Right-clicking on a process in ProcessHacker
or System Explorer
allows you to send it (File Check) to Jotti's virusscan
. Process Hacker also allows sending it to Comodo
Right-clicking on a process in Process Explorer
or AnVir TaskManager Free
allows you to send it to VirusTotal
If you are using Firefox, you can use the VTzilla Add-on
to check (analyze) a file for malware at VirusTotal
before downloading and saving it to you computer.
When using such tools, I generally recommend to get more than one opinion...
