Typically most of the antivirus vendors are recommending to run a full system scan regularly once a week. This may be quite complicated as the full scan usually takes around 30 minutes. Of course you can still work during the scan process, but the whole computer is usually running slowly.

However Avast has a solution called scan scheduling. You can schedule an automatic scan which will be performed daily, weekly or monthly.

Scheduling the automatic scan you can keep your computer clean without wasting your precious time. Scanning and cleaning is fully automatic, so you don’t even need to be at your PC during the process. You can setup which actions will be performed when the scan finds a virus.

Ready to schedule your first scan? Follow these 4 simple steps.

Quick Summary

  1. Open your Avast and go to Scan > Scan for viruses
  2. From the dropdown menu select Full system scan
  3. Click on Scan Settings at the bottom of the screen
  4. Go to Scheduling and tick Schedule this scan (we recommend Weekly)
  5. Confirm by clicking ‘OK’

2. Schedule a Period and Time of the Automatic Scan

Once the scan settings are opened, navigate to last item called ‘Scheduling‘. Tick option ‘Schedule this scan‘ and select the period in ‘Schedule Type‘. You can chose from once, daily, weekly or monthly. We recommend selecting ‘Weekly‘.

Also we recommend selecting ‘Wake up the system to start the scan (if in sleep mode)‘ to make sure the scan will start even if your system is in the sleep mode. Launch time and day is really up to you, but please keep in mind your computer needs to be turned on so the scan can start.

3. Setup Automatic Actions During the Scan

Once your scan is scheduled move to section ‘Actions‘ to setup the automatic actions when the threat is found. First of all you need to select the option ‘Automatically apply actions during scan (check this box to select an action)‘.

Then select what type of action should be performed. We recommend following settings for viruses, PUPs (potentially unwanted programs) and suspicious files

  1. Fix automatically
  2. Move to Chest
  3. Delete

4. Check the Scan History (Log) for the Results

When the scheduled time passes you should check the scan log to see if some viruses were found. Open your Avast interface and go to ‘Scan‘ » ‘Scan for viruses‘ and click on ‘Scan history‘ in the bottom part of the window.

You should get the same window as shown below. Find the latest scan and make sure it is the one which ran automatically. In the scan details below you can see how long did the scan take, how many files/folders were scanned, amount of tested data and most importantly the number of infected files.

    Iv set an end of day scan , and Shut down PC on completion, is Avast limited to Only option being “shutdown”, I’d like to be able to have log off as an option, but I don’t see that anywhere ?
    Perhaps I should request an update from avast if it isn’t an option
    Kind regards .,… Stuart

    I just got Avast and set it to do a full system scan daily at 11:30 PM (23:30) and I checked the box that says “Wake up the system to start the scan (if in sleep mode)”. However, the scans don’t seem to be happening, and instead happen sometime after I start using the computer in the morning. Is there any way that I can fix this problem?

    I accidentally scheduled 3 different automatic scans. How do I delete the other 2? Or will Avast just go with the last scheduled scan set up?
