This morning decided to do a computer spring clean. Doing a scan using Ad-Aware SE, Avast kicked in stating that there was a virus present. Followed the Avast instructions and dealt with the warning!.
Avast is running all the time, and is updated automatically, so I assume that everything is running to plan.
Question: How did Avast miss this virus (if there was one), as no previous warning had been given.The computer was connected to the internet at that time, so the virus had not just crept into the system. Should I have doubts about the effective detection rate of Avast!.
It's worth remebering that Avast doesn't run scheduled systems scans as default.......you have to set it up to do that.
AVG runs daily checks as default.
All that means is you might well put or get an infected file on your pc that wont be picked up unless you choose to scan the pc,or have set a regular(or screensaver) scan routine OR most importantly, it tries to open or run.....then Avast will pounce.
AVG will get the file on a routine scan.
Both will protect you pc from the malware.I prefer to choose when to run my full system av scans so the method employed by Avast suits me better than AVG.
