delete is not the best idea? you should tell us a few hours ago dude…
I have that version. So, in my situation everything was moved to the chest and not deleted…so I just restore all the items from today’s scan, then run another boot scan to be safe?
Ok, I was able to control-click multiple files and restore them all. Quite laboriously, I must say.
I have read in some other threads that the entries will stay in the chest unless you delete them after restoring, which I don’t want to do. I’m going to leave 'em in there just in case.
I hope someone will help the people who deleted files (glad I chose to move to chest instead). I think this whole incident deserves a sticky post so people will know what to do.
I feel like taking a chill pill and lying down now :o
(And I still love Avast, just don’t do this again!)
You can also shift-click (start and end) or use select all (Ctrl + A - but watch out for stuff you had in there previously if applicable…)
Well, I personally have been saying that since I began on this forum, as have others…but that is not the point.
My point was that this should be a lesson to everyone, that deletion shouldn’t be a default reaction, since things can, and ultimately do, go wrong.
Yep, I’ll be moving to chest from now on >:(
hey, you’re getting obvious FPs after a bad VPS update, then you choose to delete files… (while others stupidly ran full/boot time scans)… and you’re coming here to insult everyone? now you chill out okay ?
ok got it! and you are right (I should be wiser there) delete isnt the first option but what if we stupidly deleted files during the boot scan ? is there a way to restore these files? with a system restore maybe? cause the computer lost its sound after that… 
thanks for helping in advance
System Restore wont do it, I already tried.
sigh! thanks Ssscrudddy
lets hope the avast team will come up with some idea
the problem with system restore is that you may restore the bad VPS…
how about restoring the system in safe mode, then uninstall the bad VPS (remove avast still in safe mode) and then restart and reinstall avast from scratch? would that help maybe?
sorry if I sound stupid with those questions I don’t know much about computers, just the basics so I do silly things and ask stupid questions
well it didnt, I checked for that also. It left it at 110411-2
Had to laugh at this tho
So you’re now insulting every one who ran the boot time scan, yet having a go at other peeps for being insulting!!!
feeling hopeless here, I may have ruined my friends pc ???

Logos, I think you’re being a bit harsh here. Not everyone is familiar with false positives or what to do when Avast starts finding crazy amounts of files. For me, this was a first.
I was prompted by Avast to do a bootscan after I did a quick scan and it found “133 infected files”. I thought maybe I should check here first and now I wish I had, but in the heat of the moment one tends to panic a bit.
I have really learned a lot from this incident, and I think it could be treated as a ‘teachable moment’ instead of yelling at people. Just my two cents :
Malta I tried to check here before deleting but the site was down for more than an hour so being trustful to avast I deleted the files, my first false alerts ever too
paraxeno, I tried to get here too, and the site was taking forever to load which increased my paranoia about a possible infection. That’s why I ran the quick scan and etc.
I guess we’ve all learned something today. They say experience is the best teacher, but ARRGGH…I coulda done w/o this one!
exactly the same here malta, and I was helping a friend with his computer which makes me feel double responsible 
if we have deleted important files that caused the sound to disappear, worse thing is he is a musician using his computer for work and what is a musician with no sound?
we certainly did learn a whole bunch today !!!
Not the first false positive:

Guys, I had the same problem with today’s update. At first, all sites were “infected”. Then I started a full system scan in Avast! which found around 12 “infected” files. I forgot what exactly it was, but I deleted all of them. Then Avast! asked me if I want to run bootscan but I said no. So, is something wrong if I deleted those files? I’m scared now.
Had the same problem. Initial system scan found a bunch of high risk trojans and whatnot, moved them to the chest and advised me to do a boot scan. Did the boot scan and it found something like 10,000 infected files, also moved to chest. Logged back on and got the 110411-2 update, did a system scan and found zero infections. In my chest there are nowhere near 10,000 files but there are a lot.
I want to restore them as people in this thread have been doing but I am afraid some may actually be threats.
Several have [Trj] assuming for Trojan, [Heur] no idea, and [Expl] assuming exploit, tags after their entries.
Are the ones with the tagged REAL Trojans, etc. or were they false positives from the bad 110411-1 update?
Should I keep the tagged files in the chest and restore the rest?
Thanks all.
