>Really two issues:

On matter of security, not Avast (even if kept it installed untill now), or not a single one software (but a group of these freeware software)...

On 2/3 times in a month (on same day) I run:

JRT
ADWCleaner
ZHPcleaner
Combofix (sometimes)
CCleaner (sometimes)

This is what makes me feel safe (I do not know if falsely)... All of those was recommended by a friend, his is a teacher in a school of computer hardware...

>>>Did you turn off Avast! It's very likely the built-in Windows Defender will give you all the AV you need.

>>Well..Anyway, I decided to follow your advice... just uninstall Avast and turn on Windows Defender...
