Hi guys! I have some problems with my Avast. I've downloaded Avast Free 2015.10.2.2218 and the setup went well,but then it says that I'm not protected. If I click Start now or Resolve all,nothing happens. I also tried with other antivirus,to see where is the problem,and the same thing happens,I can't enable real time protection. Moreover,I have a program which has that shield, which means that only administrators can access it,and it won't open,although I am administrator(this is the only account on the laptop and it has admin rights).
I've read others topics here with the same issue,tried uninstalling and reinstalling several times,but nothing changed. The only security/cleaning tool I have is CCleaner.
Do you have any ideas? Thanks in advance!
