After updating, no full-time scan for viruses (one computer only)

[REDACTED]

So I updated Avast on my computers today. It went well on my Windows 7 laptop, but not so well on my Windows Vista desktop.

It updated, however, when I go to "scan," there is no "Full-time" scan. Only a "Boot-time" scan.

I didn't really do anything wrong. I'll be honest here though, recently, the list of scans on my Windows Vista desktop has been weird with a lot of ? scans in the list.

I'm not sure what to do here.

I'd rather not do a clean un-re-install of Avast on my Vista desktop but I may not have a choice.

Anyone have any ideas of what to do and how to fix this? I'd really appreciate any help with this.

Thank you.

I tried it. No change.

Is there anything else I can do or do I have no alternative but to do a clean un-re-install?

If I have to do that... I don't exactly remember how to do it.

Doing that worked.

I don't know why a lot of GB were taken up on my hard drive space, but hopefully, everything is fine now.
