Title: since recent updtate, error: avast web shield has blocked access to this site
Post by: REDACTED on March 19, 2015, 11:37:47 PM
since updating avast a couple of hours ago i cant access google, yahoo or a much of anything unless i turn off web shield. running windows 7, avast 2015. everything worked fine with no problems until i rebooted machine after update. have googled this but nothing seems to address the problem. only thing that works is turning off web shield which makes it pointless. any help appreciated.

apologies for not printing full error message, it reads: avast web shield has blocked access to this site as the certificate is invalid, gives address of site after this eg: google.com etc. once again, any help appreciated

Perform a clean installation of avast.

hi, wanted to avoid that, but since clean install no change, only solution i can find at present is to turn off the web shield. very annoying but any help appreciated.

Have you tried unchecking the HTTPS scanning option in the Web Shield settings ?

Did you use the uninstall tool before doing the fresh installation ?

hello and yes, used it in safe mode. turning off https scanning has worked, but whats the point of including such a feature if https pages cannot be browsed....unless turning off the feature. i havent tried using any other browser except firefox, i dont use any other so no point at least as far as i am concerned. some googling shows i am not the only avast user experiencing this issue. not happy with this, it seems like bad coding, and am wary of an antivirus program with bad coding. have used avast for years and not willing to change but maybe that time.

Try a "Repair" of Avast: Go to Control Panel > Programs and Features > double/click on Avast in the list to go into setup and select "Repair" and see if this helps.

Hi laksrool, tried a repair but no change....i didnt expect much as if you remember, this is a fresh install. so once again, problem is resolved, if as an avast user, im happy to forgo https scanning. now, personally i always use firefox and always in sandboxie, so, web shield may not be the biggest loss to my security if sandboxie is doing its job, but again, what is the point of a browser protection system that only allows a user to browse if the protection is turned off....bad coding, does anyone in avast read these posts.....or test their software before release? not complaining, but am looking for an alternative, its just getting too big, awkward and doesnt do what it says on the tin, unless you switch protection off????? thanks again for input, very much appreciated.

This is an avast issue with sandboxie.
It has reportedly been fixed here.

hello Velociratptor. only seeing this now as was away from machine for a bit. i dont see much in the link provided in regard to sandboxie, except to say "the sandboxie issue has been fixed."  and clearly it is not fixed...or it would work? are they even talking about the "sandboxie issue"? ? ?? nothing is clear in that link and being frank, it tells me nothing except an unknown sandboxie issue is fixed, what issue? and im still unable to browse https sites with https blocking enabled in sandboxie.....wtf, pardon my french but again, wtf?

Just perform a clean installation of the latest version and see if it solves your problem.

hi, have performed several clean install's, firsty removinc avast with removal tool. look, with https turned off in sandboxie its not that big a deal. i originally posted because i wanted a workable solution, and that actually is one. if i need to use browser outside of sandboxie i'll switch it on. i only posted back to velociraptor cos i couldnt make sense of the link supplied in the context of "the sandboxie issue" it doesnt even mention what sandboxie issue, is it same issue? ....if anyone else can then im listening, but thats about as far as it goes, i wanted to respond because velicoraptor took the time to post, im not sure what the link is all about, but i think a response is always required in forums....but problem, while not solved, is at least worked around....and again to you too eddy, replies appreciated as ever, but workaround will do. if it gets resolved in future releases great, if not, what the hell. thanks again.

Did you download the update for your version from the link in the first post that I linked to then do a clean install with it?
Note that this version ends in a "5", 2015.10.2.2215.
The main release ending in 2214 will not sort your issue.

No, i didnt download from the link, just to clarify, im not using beta, using stable. can you clarify also, is the sandboxie issue mentioned the same as the issue im having? the reference might refer to something entirely different, but i would also say, dont put yourself out too much on this as i feel confident enough browsing in sandboxie with https scanning off, and if the issue is the same and addressed in a beta it will roll out soon enough. but thanks again.

After ugrade to Avast 2015.10.2.2214, avast web shield has blocked access to all sites bacause cut access to DNS Servidor. With nslookup home I have: Servidor: UnKnown; Address: 192.168.1.1
Already try new instalation of the avast, FireFox was removed, Chrome was instaled, avast 2015.10.2.2215 was instaled and no more internet access.
There is any problem with SO Win7 32bits?
Tanks,
António

Yes it is the same issue. The beta has been made official so you should get it via the gui soon.

Hello. OP here just adding a quick word. Since update just now this problem seems to be resolved. Kind of knew it would as stated in the link posted by Velociraptor, also the two avast processes so all good. Been a while but thanks to all.

Same problem here, recently.  I have no idea where/what the problem really is, but blocking "HTTPS Everywhere" that i installed in Firefox a few months ago seems to be a work-around.
