I have used Avast for over 2 years, but all of a sudden, 3 days ago, it turns itself off. I cannot “fix it”, nor upgrade, etc. I have attempted to down another free version, but I cannot download any anti-virus programs. Anybody know what gives?
If you cannot download any AV programme then there may be an infection
