Obviously yes.

Since you don't show what was scanned we really can't go into any details. So I have just started one off on my system whilst typing this. By the time it is done now (1 minute), if I run it again it is likely to be quicker, just started that off and it took 12 seconds. So I would say it has time.

@ marc-d-l

Go to PROFILE then Modify Profile then Forum Profile Information then Signature: and put information about your system just like my signature about your system just like my signature so that the helpers can offer pertinent advice.

If its good enough for DavidR an avast! √úberevangelist then it is good to have this information in your signature.

Am ussing Vista ultimate 2gb memmory 250 gig hard drive,comodo firewall.and malwarebytes.My last two scans (quick scan)37 seconds. Full scan 11 minutes 23 seconds.
By any standard this is fast.
P.S. that was after i had already done a full scan.

avast!5 is capable of remembering what was previously scanned and then on subsequent scans it only scans new files or old files that have changed since the last scan.

Not quite correct as the function that speeds up scans is the Persistent cache and this doesn't cover all files.

Use persistent caching - if persistent caching is used, the information about the scanned file is stored in the permanent memory. This means it is not lost after a system restart and it is also not affected by virus definition updates. Consequently, persistent caching is suitable only for files which are guaranteed not to contain any virus infection e.g. operating system files, files signed by trusted publishers, or other files covered by the avast! whitelist. This box is checked by default; if you want all files to be scanned regardless of their trust status, this box should be unchecked.
