I would also suggest updating your Avast software and its anti-virus engine to receive latest updates and remove threats and viruses on your computer.

However, if the problem persists, I highly recommend using alternative security software if you doubt your Avast is not doing its job, I suggest using SecurityReviver program, Security Reviver identifies threats and vulnerabilities on your PC and will neutralize them quickly and easily. It then constantly monitors your PC to ensure you’re protected against future infection.

Hi Aldert,

If your Avast is not detecting any virus, either it might be an issue within the software itself or it is also possible that there are no virus present in your PC/laptop.

If certain program components and features are not working properly in Avast Antivirus, I would recommend you to repair your installation using the Avast Setup wizard. The repair process resets your software configuration by fixing or replacing program files which may be out of date, corrupted, or missing.
You can access the Avast Setup wizard from your Control Panel in Windows.

Fix 1: Please follow these steps using the Avast Setup wizard which you can access via the Programs and FeaturesAdd or Remove Programs section of your Windows Control Panel:

1. Press the Win key and X key simultaneously, then select Programs and Features from the menu that appears.
2. Right-click your version of Avast Antivirus, then select Change from the drop-down menu.
3. When the Avast Setup wizard appears, click Repair.

   

4. When the update is complete, click Done.

   

Fix 2: Manage startup apps

A startup application is software that opens when Windows opens. Over time, as you install more and more apps, the number of startup applications increases. Common apps that load and run in the background are security software, Windows Update, instant messaging software, and multimedia apps. You can increase system resources by stopping some of these tasks from loading, or by changing their settings.

1. From the Start screen, type msconfig to open the Search charm, and then select msconfig from the search results.
   
   The System Configuration tool displays.
2. Click the General tab and make sure Selective startup is selected.
   
   
   
3. Click the Startup tab, and click Open Task Manager.
   
   The Task Manager window opens with Startup tab selected.
4. Select any startup items that do not contribute to the system and are unwanted, and click Disable.
   
   
   

   If you are unsure about an item, write the name down and research it on the Internet. Do not disable an item if you do not know what the item is.

5. If prompted, click Restart to restart the computer.
6. If Windows or other software stops working after a checkmark is removed from a task, restart the computer and reverse these procedures to replace the checkmark. 

Fix 3: Choose a different antivirus/security software

You can use Security Reviver.
