Moved from Help section to VirusScan.
The message says an unepected error occurred during a scan. Not one I've seen before : any ideas about the cause?
Rest of translation
"click OK to return to the home page, then try to repeat your analysis"
Also the words under the popup says "analysis in the background" so you are running the scan in the background?
Seen it sometimes but rare.
Have you contacted support? they should know of it and the fix.
Open IE – click tools – Click internet options
Under advanced – click Reset
Close all windows and then try to run a scan
Though my suggestion of a reinstall fixed it in this thread
well i think it got corrupted so you should try reinstalling but if it persists then contact support to fix it.
