I was woundering if someone has had this alert from avast: lsass exploit (esk). I haven't had avast 5 installed for long but even so i had this alert before with avast 4.8. Avast blocked this threat 3 times yesterday, so i preformed a full system scan and everything came up clean. I update everything in my pc which needs to be updated ie firewall (comodo) and avast its self but im worried that something evil is inside my pc trying to call home. I must stress i dont wounder off to strange and wierd web sites, I just shop and game.
