File Reputation

There is an option in WebShield “Warn me when downloading files with poor reputation”. Its disabled by default. Currently I am testing Avast Free with this option enabled & must say this works as a good measure in combating zeroday malware. Today too I tried downloading fake Skype, Tuneup Utilities & other zeroday malware & it detected good.

I would like to enable this in users system I have installed Avast. But as its disabled by default so couple queries —
Will it affect & warn for Windows Updates?
Can it also prevent drive-by-downloads & exploits?

Would it be good if it is also implemented locally?
Currently it only warns for files coming through web.

There are some issues with the windows updates, be sure to allow these.

You mean FileRep blocks some Windows updates?

Windows updates, Microsoft files, Windows files, etc are not whitelisted?

Yes, it’s based on how many people have seen/downloaded the file etc. And other factors such as digital signature so you could get a lot of false positive warning thus why it’s off by default.

I got these warnings some day ago with 6 of them.

Avast doesn’t block, but alerts, so did you get any alerts ?

So far on both of my systems XP Pro SP3 and win7 SP1 I have had no issues with windows update being blocked. That has been the case even from the early beta testing of avast 9.0 through to the latest version 9.0.2013.

I asked coz I like the feature & thought of enabling it on others users system.
But as you guys mentioned may warn about windows updates so could be a prob for users as they are average users & they would not know what to do. So I will keep it at default i.e disabled.

Thanxx for the info guys.
