Please report this false positive to Symantec so they can fix their error. That's a generic "we think this may be suspicious" error that doesn't mean there is any virus. If you check the analysis of evince.exe, you'll see it's a Symantec/TrendMicro generic error issue that they'll need to fix.
Sometimes, the impossible can become possible, if you're awesome!
