Eset 6.0.308.1 and then Win7 64bit freeze opening scan report

Hi all !!
I just installed latest version of ESS took from Eset website, and I ran an intelligent scan. I noticed that during scan my USB logitech webcam continue to disconnect/reconnect and at the end of the scan, opening the report and/or double clicking on voices in it, ESS freeze and after a while Windows 7 stop to respond and I must reboot via HW reset of the PC
Can it be a bug, or I did something wrong ?
I uninstalled ESS 5 before with it uninstaller, and reboot PC. Now I returned to ESS 5 but I'ld like to upgrade it to the latest version.
Thanks very much for help
Have a nice day

install again the latest version.
remove the camera from the computer and do the scan again.

see if it might be an issue with the device.
