Using the Avast 5 Free Version, I wondered what you would recommend as an optimal weekly Scan: Quick Scan, Full Scan, or Custom Scan?
Looking at Quick and Full Settings I notice that under Packers, the default seems to be restricted to 3 Packers and recommends a Custom Scan to include the rest. Is the default Setting adequate, or which Setting would you recommend for the weekly Scan using Custom? If so what Settings for Custom Scan do you recommend?
The reason I ask is that although I don't tend to surf dangerously, of the 4 security measures running on my laptop, whenever something really nasty tries to download, AVAST is the one to raise the alarm : Threatfire reacts to some things that Avast misses usually FPs, pre-installed Windows Defender also works quietly in the background but never reacts to anything important, the Free version of SuperAntiSpyware which I activate for its scan catches only harmless cookies.
A good example was: I inadvertently downloaded something called the YouTube Downloader Bar with an update of the YouTube Downloader, which obviously must have contained a “sleeper” because some days later, whenever it tried to activate itself Avast told me loud and clear and blocked the process. Threatfire wasn't aware of it, nor did my regular SAS quick scan show it. I immediately ran an Avast Quick Scan and located this YouTube Downloader Bar, and although it would not open it, repair it or send it to the Chest, it enabled me to simply delete it.
Back to my question – Avast is the best gear I have had as a first line of defence (I am wondering whether to junk Threatfire and SAS), but would like your opinion on the best Scan to scan for any other “sleepers” that may have come in under the radar.
