How to run boot time scan from safemode

Hi,
I’m not sure whether its the safezone browser or a real virus causing my win vista 32bit system to slow down to a crawl and then eventually freeze where I then have to do a hard reboot. I am able to reboot and login after a very long time and eventually get the freeze again. I can enter win safemode and things seem to run fine.

  1. I’ve tried to disable all but microsoft processes from starting in safemode and reboot - same problem.
  2. I ran malwarebytes in safemode and found nothing.
  3. I tried running avast in safemode but it says that it cannot establish an endpoint or cannot get the endpoint.

Questions:

  1. How can I run boot time scan in safemode? I tried this once and avast tried downloading some files first. It could not do that because although I did boot into safemode with networking, I only connected to the local network but not through our provider. So avast could not get files.
  2. Is there some avast executable I can run in safemode that can trigger a scan (to run in safemode)?

Thanks, until I get some ideas my work machine is down.
Please give this a high priority.

Thank you.

Q1 and Q2 > You can’t as avast doesn’t work in safe mode.
