My computer grinds to a screeching halt whenever it’s time to scan. No matter what “Power option” settings I use (ranging from more conservative usage to powerhouse performance), my task manager tells me that Avast takes immediate and total control of the Disk, meaning fck what I was doing and especially fck my internet usage. Like, my network ceases to exist whether at home or in public. Would insert a screenshot but html is not having it.
Do you have more then one AV installed?
No, not that I am aware of.
Check that your scan settings are set to normal or low
When I used to do scheduled scans, I always set them to run when the computer would be on but I wasn’t going to be using it heavily (which would eat resources), aside from the on-demand scan it has all of the real time scanning to do.
- 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 used to have avast set to do a scheduled weekly Quick scan, set at a time and day that I know the computer will be on. But I have ceased this practice for some time now, based in the above.
Well, next issue in that is, I can’t find the scan settings or scan schedule settings. Does avast take that responsibility out of your hands?
Edit: never mind, it seems you have to specify “scan for viruses” to get to these options.
See my screenshot that shows the settings and a scheduled scan is under the custom scan link
