I have a 64-bit Windows 7 Home Premium notebook.
As an antivirus I have installed (and updated) Avast Free (the free version).
For a couple of months, I have been noticing a certain incident that occurs randomly (that is, it does not always occur, nor do I find any specific reason to trigger it) but it is happening more frequently (although it is not always happening ). The incident is as follows:
-I start the notebook.
Down to the right the Avast icon appears with a yellow triangle with an exclamation mark inside it.
- I open the Avast user interface and the following message appears:
"He's vulnerable.
Some shields are disabled. ACTIVATE."
Clicking on ACTIVATE displays: "You are protected".
That is, the notebook is initially initialized with Avast "turned on", while on other occasions, it is initialized with Avast with the shields deactivated.
Observations:
- This happens both when starting and restarting from now on I will refer to booting without distinguishing both cases).
- If when I boot the shields appear disabled and I stay two clock hours without using the system ... they do not get up (there is no magic).
- If the activated shields appear the boot I can use the notebook for two days that do not fall.
- I used the following tools to detect malware leaving the system very clean:
Mbam (Malwarebytes Antimalware) 3.1
Eset Online Scanner
TDSSKiller
AdwCleaner
Junkware Removal Tool
- Use the following tools to erase "broken" entries in the registry and weed a bit to the system:
Ccleaner
Argente-Registry Cleaner
Glary Utilities
- Then I uninstalled and reinstalled AVAST Free (to uninstall use avastclear).
- The problem persisted. I re-uninstalled it and installed it following the following link:
https://www.avast.com/es-ww/faq.php?article=AVKB94- Windows is original with updates to the day.
- Avast Free is updated both the program and virus definition.
Program: 17.5.2302 (build 17.5.3559.0)
Virus Definition: 170627-2
- Dejo una imagenes para mostrar una idea mas pictográfica del asunto por si no me expresé bien:

- What I notice is that it is a shield that is not activated:

At least how can I know which is the shield that is not activated.
Thanks!
