Passive Mode disables all active protection, such as Core Shields and Firewall, so you can use more than one antivirus program at a time without interfering with the performance of your PC or the reliability of antivirus detections. In Passive Mode, Avast Antivirus still receives all virus definitions and program updates that allow you to manually scan for issues on your PC, but Avast cannot actively protect you.
Avast Antivirus is a family of cross-platform internet security applications developed by Avast for Microsoft Windows, macOS, Android, and iOS. Avast offers free and paid products that provide computer security, browser security, antivirus software, firewall, anti-phishing, antispyware, and anti-spam, among other services.[2]
In January 2020, multiple news sources reported that Avast Antivirus, through a subsidiary, was selling the browsing history of Avast Free product users. Though the company claimed all data was "de-identified", it was reported that the sold data could possibly in some instances be linked back to people's real identities, exposing every click and search they had made.[6][7][8] In response, Avast announced that it would close the subsidiary over the data privacy backlash.[9]
I'm an amateur programmer, and I'm getting desperate and mad because of a big issue: most of my programs are blocked by Avast Antivirus, while some aren't, and I don't understand why.The more I try to investigate, the less I understand what the problem could be.
There are already many topics about that on the web. However, most of them give only superficial answers: they just explain how antivirus software works with signatures and detection heuristics, or state that you just have to add the offending application in the white list without asking any other question. While it is certainly correct, it's not acceptable answers in my sense, because I'm still left with my own programs that refuse to work without any concrete idea to start investigating.
First of all, the only antivirus software that blocks my programs is Avast 7.x. No other antivirus software see any inconvenient to run my software. Secondly, I haven't installed Avast myself; it is installed on a friend's machine.
I have Windows 7, and he has Windows XP. I'm completely sure that the problem is avast only: when it is temporarily disabled, or if the program is added to its white list, everything works nicely as expected.
The first one is open source, and I can give a link to the executable and the source code if needed. The two others are closed source but free to use, I can give a link to the executable of the current version only.
The only obvious common things between these three programs are me as a developer, my Windows 7 machine that compiled them, the compiler family which is MinGW/GCC, and they are all Win32 GUI applications without any framework (no MFC, no WPF, no Qt, wxWidgets or whatever; just pure Win32/C GUI applications).
This is unacceptable. Newbie users of my program, especially the game, don't know how antivirus software works; don't know how to put it into the white list and why it will unblock it; don't know how to change settings of their antivirus software; if they see the pop-up, won't understand it and will end up being afraid or disappointed because they can't play without knowing why; and if they don't see the pop-up, I can't expect them to wait 5 minutes with a half-freezing computer. each time they want to play.
Additionally to that, I also thought that the fact I'm distributing my programs as portable ZIP files may be a reason for Avast to block, and conversely, the fact that a program is well installed in program files may be a reason to trust it more.
So I made a simple experience: I compiled a new Inno Setup 5 installer for the beta 2.0.0 of my game, as well as one for the version 1.3 of my text editor, and discover that the installers themselves were blocked!
I made another experience with my friend, where I tried to find exactly the place where the programs crash, based on using MessageBeep (MessageBox is also blocked!). I didn't noticed anything problematic. The game is blocked when SetDlgItemText is called for the first time in the login dialog box, but if I remove all SetDlgItemText it is blocked further down. In the text editor, it is blocked while populating the menu bar...
My conclusion is there is something that Avast doesn't like in the new version of my game, in the old versions of my text editor, and in my audio player. Something that is absent in the newest version of my text editor. What could it be? Do you have any clue? Do you have only an idea on how I could proceed to find what it is so that I can hope to fix it? Is there only a way to analyse such a problem, or is the whole world screwed by Avast?
Note that I'm a single person and not a company, all those programs are free to use, I have not pay any IDE to develop them, and I'm not paid by the users when they use them, so I assume that a certificate is probably not affordable at all. Moreover, I don't know if it's a true solution, how to sign an application compiled with GCC, and I really don't want to switch to an "usine gaz" like Microsoft Visual C++ (MSVC). I would prefer strongly forget that option if there is any other solution, even a very dirty one.
Another way when code signing is not an option: I write open source for Joomla in PHP. After I received the first indications that Avast marked my file as a (false) positive, I contacted them and they whitelisted my file within hours.
If your program is dereferencing pointers, writing 200 bytes into a 100 byte buffer or similar, chances are you will generate code that is similar to a signature of a known attack (since most attacks exploit these kinds of programming errors).
Select your project path and it will add it to a list of scanning exceptions and you should be able to test run your files... it worked well for me. I also disabled deep scan in the same menu due to a suggestion from another member.
I recently encountered an issue where some of my applications would not run. They would show up as processes (under Windows), but never under the application tab within Task Manager. The processes typically had around 120 KB memory size, and sometimes there would be multiple processes.
Then find and click the 'Exclusions' option from the menu on the left side. Add your project folder in the file exclusion list. This is safe unless dangerous viruses crawls into your project folder without your knowledge :P
When I'm trying to start PTCCG Live due to Avast conflict application is stooping with info: No network found please try again start application: it is quite popular antivirus can you solve the problem
I would recommend removing Avast, especially if it is a free service. Your computer likely is already protected enough without additional software. If you have concerns about viruses I recommend using Malwarebytes.
-us/discussion/comment/8703#Comment_8703with all due respect i bought avast and PTCG Live literally the only game/application that having issues connecting etc... seems weird. If I want to play I do need to shutdown all anti virus functions then wait for it to go after the 5/37 loading process then reactivate it. it bothers me every time I open Live while the old TCG had no issues with it whatsoever.
This game is ridiculous to have to shut down Avast, after paying for pre,ium security, This game is not worth all that, either are the cards that I am unable to redeem, due to the fact I cannot play the TCG live game.
No one needs extra anti virus programs these days as windows own protection is just as good since the time Win10 got released. Extra anti virus programs are even known for slowing PCs down and cause a lot of other issues.
Normally if you add an exception in either one of AVG antivirus products, including Avast, you have to close the browser completely, and then re-open it for it to take full effect, as the domain resolution itself is very heavily cached if you use any chromium-based browsers.
AVG blocks harmful traffic by preventing the DNS resolution before attempting to block the connection via firewall which is a more effective way of doing things, however, chrome caches this DNS resolution so even when you add an exception, chrome still thinks the domain does not exist, so you gotta restart that browser before trying again.
I know that Avast isn't a very reliable antivirus software (is there any that is reliable actually?), so I'm nearly ready to just put 'false alarm' marks on all of these, but I want to notify you about this and get some final reassurance.
I know I've had this conversation with our Installation team before, but Avast raises red flags for a lot of Autodesk products for some reason. Any file within %localappdata%/autodesk (for Fusion specifically) will be safe as these are installed/written by us .
So, I just found out that Avast is adding it's signature to my outgoing emails. I did a bit of googling to learn a bit more about this issue, and found this question: How does avast! add a signature into my webmail?
According to the accepted (and only) answer, Avast is intercepting, decrypting, modifying, and re-encrypting emails in order to add the signature. However, some of the comments below the answer state that the answer is wrong.
Hi everybody. In the last two days we've had a couple of reports of third-party antivirus software (both AVG and Avast) showing visitors to our store a warning that /cart.js is serving URL:Malvertising malware.
Just as I posted this, I received a response to my false-positive report to AVG to say that they have cleared the reputation of our site; hopefully that will resolve the matter, but I'll leave this here in case anyone else has the same problem, or in case the problem returns!
I know this is a topic in the Avast forums, but Avast has not addressed it yet, so maybe this is happening to someone else.
I just reinstalled Windows 10 (I always do after a Creator's Update), installed my Adobe products (Photoshop, After Effects, Media Encoder, Illustrator, Audition and Lightroom Classic; all latest version builds). Avast Premier 17.9.2322 (Build 17.9.3761.278) refuses to let all but Illustrator load. In order for the products to successfully load, I have to disconnect my internet and turn off all Avast shields, then all Adobe products load as usual. There are no corrupt files, there are no viruses. If anyone has experienced this, or has a solution, please inform me.
