Thanks for the reply,sorry it was a typo I configured windows update to not update or search for update automatically,but eset alone searched for windows updates.Maybe this is what caused it,so I'll check again when another database update is released to see if it really wasnt the one that caused it.Since I used other antiviruses,I am getting confused with the type of scans in eset,the smart scan is like a quick scan and the in depth scan is considered a full scan?After every database update, does it scan everything or just commonly used files?
