Constant avast messages saying a harmful webpage or file was blocked

Viruses and worms
1

Hello,

I’m having a malware issue, avast web shield keeps having to block harmful webpages or files. I’ve followed the instructions in the other thread, and attached all the logs mentioned.

Any help would be greatly appreaciated! I’ll keep a close eye on this thread so that I respond as soon as possible.

At the moment the aswMBR scan keeps getting stuck on FRST64.exe for some reason, for over 30 minutes, so I am unable to provide that log at the moment, any ideas why that would be happening?

Thanks,
Cam

At the moment the aswMBR scan keeps getting stuck on FRST64.exe for some reason,
that log is probably not needed ... but you may try run it form safe mode If needed, they have other tools that will do the same

Just to update, the final scan finished eventually, so I have attached it’s log to this message.

Thanks,

Re-install Chrome

Unless you did this yourself, malware has changed your Chrome version into the Development Build. Among other things this allows malware to install any extension it wants. We need to resolve this.

  1. If you have bookmarks, let’s save them by exporting them - Export Bookmarks
  2. Then I need you to go Google Sync and sign into your account
  3. Scroll down until you see the “Stop and Clear” button and click on the button. At the prompt click on “Ok”
  4. Now we need to uninstall chrome.
    Note: When asked about user data or settings you must remove this also so please check the box.
  5. Restart the computer and reinstall chrome, You can download The latest version from here - Google Chrome
  6. Import your bookmarks back into Chrome
  7. Sign back in to your Chrome browser so that your bookmarks sync with your online account.
