smart scan very slow
« on: February 28, 2017, 02:22:40 AM »
Windows 10 Pro, 64 bit, Avast free (17.2.2288). 2 year old fast Dell laptop, 8 GB memory, 140 GB files.
 Smart scan, which ran 2.5-3 minutes in previous version, does not finish in 35 minutes.
Any suggestions?

- Other security related software installed..?
- Which AV(s) did you use before Avast..?

On this machine, Avast was the first and only AV.
Malwarebytes Anti malware 3.0, demoted to free version.

1. Download Avast Free Antivirus: https://files.avast.com/iavs9x/avast_free_antivirus_setup_offline.exe
2. Follow instructions: https://www.avast.com/uninstall-utility (Run this tool for all prior installed Avast versions..!!)
3. Reinstall Avast with the downloaded installer from point 1.
4. Reboot.

Downloaded Avast offline installer.
Downloaded Avastclear, ran.
Rebooted, installed Avast.
Removed  options not needed.
Ran smartscan - 30 minutes. Checked options - all harddrives were marked.
Removed all harddrives from options.
Ran smartscan - 2 minutes. Probably I should have done it earlier.
(If, at the end, I click on "details", the scan restarts. Oh well, you can't have everything)
Many thanks.
