Prevx1 - Questions

[ErikAlbert]

For the record : I removed my post from the thread "Considering Prevx1", because this thread is turning into an endless discussion and I "consider" to keep Prevx1, if I get answers to my questions.

Subject :
1. Unknown Programs
Behavior for unknown programs : Query, Allow, Block.
and
2. Caution Programs
Block Caution programs : Enable, Disable, Query

Question :
What does "block" exactly mean ?
Does it prevent the installation of the unknown/caution program ?
Does it prevent the execution of the unknown/caution program, even when it is installed ?
Does Prevx1 have to consult the Community Database to know if a program is unknown or caution or does it consult one time and stores that information in the Local Database ?
What happens if the internet connection isn't good or the server has problems ?

TIA :)

It means that instead of asking you whether you want to allow it, it just automatically blocks the file from running at all. It looks up the file in the community database to see if it's good or bad, if it's neither then it's unknown and it runs the information through heuristics, at which point it *might* be marked caution, and if it can't determine it good or bad heuristically then it will ask you what you want to do but check back with the database periodically until it's marked good or bad. If it can't connect to the database, then it can't see if the file is good or bad, so it's unknown.

Devinco asked for some info on how Prevx1 works, and I made a rather long writeup here: http://www.castlecops.com/t168087-Does_Prevx1_block_kernel_drivers_and_services.html

If you block all unknown and caution programs, you won't get any bad stuff on your computer in theory and what isn't there doesn't need to be removed.
Keep also in mind that Prevx1 is getting stronger every day because of the Community Database.
For the moment, I don't take any chances and my frozen snapshot will remove all the bad stuff.

-{ Quote: "and after the trial month does it keep updating and so forth...... just doesnt remove stuff right?" }-Right

-{ Quote: "If you block all unknown and caution programs, you won't get any bad stuff on your computer in theory" }-Indeed, malware can't infect your system if it can't run. There's not much that's unknown to the community database, so you wouldn't be missing much. Your plan sounds pretty good :)
