Uninstall avast, but still blocked Web sites

Hello, I'm new to the forum and hope someone can help out me.

So I had installed Avast antivirus free (2015) on my macbook (2014, with OS X Yosemite) and it has messed up my computer. He made sure that several of my sites that I often browse have been blocked, so I deleted the application using AppCleaner and manually deleted a load of documents and parcels connected to my computer avast. In hindsight I probably should have made use of uninstall, but I only discovered it was an uninstall program after I deleted the application. Now even more sites in my browser are blocked and are not accessible in some way. I looked in my system to see if there was still avast documents, but I can't find, and I am at a loss. Fortunately, I have an ipad, so I can make up with her, but it's a nuisance.

I tried many things to get my browsers working again: reinstall the app, so I can uninstall it correctly (does not allow me to install, because it cannot establish a connection with the server), rummage through my files (library/launchdaemon, library/applications etc.) for the rest of the files to delete, turn on/off my firewall and turn my computer avast.

For reference, this problem applies to all my browsers: chrome, firefox, and safari. I also can't access the appstore more. Also for the context as to why I even installed avast in the first place: some adware had managed to infect my computer (perfetnight) and play ads very hard on my speakers. I managed to get rid of the malware initial (I hope), but now Avast haunts my computer with a vengeance! someone knows how to fix this?

From your description, it seems that the malware still exists. It is probably a version of wicked VSearch. Check the instructions of Linc Davis in this topic: Virus/Spyware/Macbook Adware

    (I'll remove the solution as you always seem to have the problem)

    So either Windows Safe Mode and Safe Mode of Firefox did not help at all?

    You can do a clean reinstall and remove the folder from the Firefox program before (re) install a new copy of the current version of Firefox.

    If possible to uninstall your current version of Firefox to clean the Windows registry and settings in the security software.

    • Do NOT remove the "personal data" when you uninstall your current version of Firefox, because this will remove all profile folders and you lose personal data such as bookmarks and passwords including data profiles created by other versions of Firefox.

    Delete the program folder Firefox before installing newly downloaded copy of the Firefox installer.

    • (32-bit Windows) "C:\Program Files\Mozilla Firefox\"
    • (Windows 64 bit) "C:\Program Files (x 86) \Mozilla.

    Your bookmarks and other personal data are stored in the Firefox profile folder and will not be affected by a uninstall and (re) install, but do NOT delete personal data when you uninstall Firefox which removes all Firefox profile folders and you lose your data.

    If you keep problems also create a new profile.

  • "Bookmarks and history system is not functional" with corrupt files found by Avast and slow loading Web sites ONLY in Firefox

    Firefox is the only browser that allows me to connect with my microphone. I need to use this feature for an online class. Earlier tonight, the message invites me to grant or deny permission to site class to use the microphone stopped appearing and without this registration only will pick up all the sounds and I can't save anything.

    I tried to quit and restart Firefox. I had a few extensions in use at the time, in particular Session Manager. The allow/deny message would not always appear, then I restarted my computer.

    Now when I open Firefox, I see the message error "the bookmarks and history system won't be not functional. In addition, the browser loads websites extremely slowly; It takes several minutes to load each page or for me to be able to click on anything whatsoever (bar URL, menus, etc.) my other browsers (Internet Explorer and Chrome) are functioning normally and loading Web sites at a normal speed. I tried to download the latest version of Firefox, but it does not solve anything. I also tried to restart the computer again, but that didn't help either.

    I ran my Avast software system check, and it has mounted as the following files under "C:\Users\ (me) \AppData\Roaming\Mozilla\Firefox\Profiles\Irozixj7.default ' are 'damaged and unreadable ':
    -cookies.sqlite - shm
    -cookies.sqlite - wal
    -localstore.rdf
    -places.sqlite - shm

    There was one more problem on the analysis, but it is probably not relevant: the file "C:\ProgramData\Microsoft\Windows Defender\Definition Updates\{9A2C6FA7-E04E-4819-B86A-8363A9D1E42A}\mpengine.dll" it says "the system does not have the specified path. When I tried to follow the path shown, one of the files (I can't remember who) said something along the lines of "you can't access this folder, you want to allow access to this file permanently? I said yes and was able to access the folder.

    I tried to add the extension in Maintenance of places, but the speed is too slow to download anything. Trying to access any results of the menus in the Explorer freezing for several minutes then thaw but with the menu still unopened. As a result, none of the solutions found here (https://support.mozilla.org/en-US/kb/fix-bookmarks-and-history-will-not-be-functional?esab=a & as = aaq) seem to work.

    My questions are the following:
    -Is it possible to understand what caused the problem in the first place?
    Is there a way for me to fix it without losing my bookmarks and history?
    -How can I prevent that from happening again in the future?

    First of all, I recommend you backup your Firefox settings in case something goes wrong. See back up and restore the information contained in the profiles of Firefox. You can copy the folder of your Firefox profile together somewhere outside the Mozilla folder. To quickly access this folder:

    Help > troubleshooting information > "view file" button.

    Then, to keep this file open, exit Firefox and try to move "damaged and unreadable" files to another folder. With the exception of localstore.rdf, which stores the positions of windows, toolbar tools and other data non-essential customizations, other files appear to be specific session files that we hope, are not critical. If you restart Firefox, should he behave more normally?

    If this is not the case, try to create a fresh Firefox profile. It will be the Flash plugin, which is the control of sites use usually to connects to your camera or microphone and other plugins, but otherwise will be a new configuration. This article has the commissioning steps in the Profile Manager: use the Profile Manager to create and delete profiles Firefox.

    If the sites are functioning normally in the new profile, you can import your bookmarks from your old profile, as well as the copy on the other files that do not appear to be the cause of the problem. Some trial and error may be needed to determine that. This article has a few tips: recovery of data from an old profile.

    If the new profile is not better, you can exit Firefox and use the Profile Manager to return to your original profile.

    Any improvement?

  • Safari should let me block web sites

    .

    Every now and then we get a repulsive web site.

    Safari or IOS should give us the ability to block this site.

    Future attempts to access this host would result in a message saying "you have blocked this, making sure to unlock?

    In an ordinary UNIX machine, you can do a similar thing with a host file redirection, but since IOS is locked and I am certainly not stupid with rooting, I think that Apple should provide capacity probably widely appreciated to avoid the dreck.

    It is my free suggestion of the day and my 6s is awesome.

  • How to block Web sites except some systems while network in windows XP

    Hello

    I use Windows XP and all my network systems have the same operating system.   We do not have the server system, but we are processing regular system as a server...

    My questions are the following,

    1. I want to block all Web sites except some Web sites
    2. in the allowed Web sites, I want to allow only certain sites to download.
    3. I want to do this for all my network systems, and should not be oriented browser...

    ex: I want to allow only Google.com, viadeo.com, and monster.com... now, here, the user can download Viadeo.com and monster.com, but not other sites who through google.com. and I want to apply to all systems on my network...

    Please help me if possible?

    Please, I beg you.

    Thank you
    Ravi.

    No, you cannot use a standard drink as a 'server' Windows operating system computer and have it force the settings for the other computers on your network.  To do this you would need a server, run a real server OS and use a domain Active Directory to push the settings to your PC.

    The first person who responded to your question is basically asking what type of router you have because some routers do not have the ability to block websites in the router, which would mean that no PC inside your network could get on the list Black/blocked sites.  You would need capabilities of your router to see if this is possible or not research.

  • Family safety report says that a blocked Web site has been visited several times.

    OT: The family safety report.

    On my report it says that a blocked site has been visited 120 times. How is this possible when it is blocked?

    Hello

    Thanks for posting the request in Microsoft Community Forums.

    Have you checked by accessing the site blocked in the child's account to see if it's blocked or not?

    Safe family activity reports will include sites that are visited but blocked. Also, sites that was redirected from other sites, or use a feature of this site (such as the Facebook Like function and share) will add also upward to the activity report.

    I suggest you to check by accessing the Web site of the child's account. Also, make sure that the child's account does not use proxy connections.

    You can also update the family safety filter and check the results.

  • Blocked Web site / loose connection

    I'm going into an environment where we have a NSA 3500 already install. The network administrator has recently moved.

    We have a few websites that is blocked, like facebook.com. These sites are blocked by the content filter and the areas of the personalized/prohibited list tab.

    When a user accesses one of these Web sites, the page loads, you get a general message by saying: the connection could not be made. I would like to know how we can get its Setup to display the page of blocked sonicwall. For example, if you visit a Web site that is blocked with one of the built-in categories you will get a message from sonicwall, saying that content filtering has blocked the page.

    We are witnessing randomly selected sites that themselves are blocked, and we do not know if it is the firewall blocking because we do not receive a message. Yesterday a user tried to access a google document. They received a shortened goo.gl link and it was blocked by the firewall, didn't know until I connected on the firewall and tried to go to the link and then it worked.

    If someone could help with this, that would be wonderful. Thanks for your time.

    Much of the time, it's because of content filtering HTTPS, this feature via known IP addresses blocks. Please use DPI - SSL to ensure a more precise blocking traffic.
