21.11.2500 (build 21.11.6809.528)
Just upgraded from free (run fine for years) to Avast one.
1) Clicking smart scan shows blank smart scan window wits a spinning blue circle in the middle. Then does nothing for hours.
2) a targeted scan works fine.
3) pc speedup - says something went wrong - restart computer.
4) ive restarted my computer 7 times this morning since installing Avast one. Not fixing these 2 issues.
