General Topics

i have 2nd gen Core i5 3.3ghz,6mb cache, 4GB RAM…i m using win 7.
Problem is that when i start Full System scanning my CPU usage gadget shows 5-9% CPU usage… and my Avast scan 76Gb data is 22mins. about 80mb/second data is scanned… i want Avast to use my 80% above CPU USage so my scanning become faster…!! while when i use format factory for converting files my CPU usage become 100% and File is converted in some seconds… i m using avast 6.0.1367

Well… my guess is that you’d need to get a faster harddrive.

I get nowhere close to 80MB per sec, would love to, but I don’t have huge amounts of data.

A couple of things that might help short of the faster HDD suggested:

  1. I don’t know why you feel the need to do a Full System Scan, a Quick scan covers the high priority stuff, I have that scheduled weekly and it takes just over two minutes.

  2. You don’t mention the Full System Scan settings that you have or if you made any changes ?
    Crucially if you elect to Test whole files and PUPs (Sensitivity) or select All packers (Packers) as they would greatly increase the scan duration.

Some settings that may help speed up the scan are in the Performance section, namely ‘Speed up scanning by using the persistent cache’ (default I believe) and ‘Store data about scanned files in the persistent cache’ (not on by default I believe) both of these should be enabled to help with scanning speed.

These changes take a few scans before the database is built up, not all files are included in the persistent cache.

With a resident on-access antivirus like avast, the need for frequent on-demand scans is much depreciated. For the most part the on-demand scan is going to be scanning files that would be otherwise be dormant or inert. If they were active files then the on-access file system shield would be scanning them before being created, modified, opened or executed.

I have avast set to do a scheduled weekly Quick scan, set at a time and day that I know the computer will be on. If for some reason my system wasn’t on, no big deal I will catch up on the next scheduled scan.
