Marty112 Posted June 13, 2014 ID:841317 Share Posted June 13, 2014 Every time scan is completed it finds Potential Thread inside Chromes preferencesC:\Users\User\AppData\Local\Google\Chrome\User Data\Default\Preferences. This can't be solved by removing this file because Chrome recreate it each time it starts. To be honest I don't know what kind of threat can it mean to me and what can I do about. Could you please explain to me what could it be causing? I've checked for any unwanted chrome extensions but except from Adblock, Chromebleed, Speed Dial, Magic Actions for Youtube, Google documents / dictionaries I don't have anything installed. All of these extensions are from legit sources and people normally use them. Thank you for your replies. Link to post Share on other sites More sharing options...

Marty112 Posted June 13, 2014 Author ID:841334 Share Posted June 13, 2014 No it didn't help at all. Still recreated file seems to be a threat. Link to post Share on other sites More sharing options...

HiltiHome Posted June 14, 2014 ID:841772 Share Posted June 14, 2014 Marty112, do You have Chrome synchronized with Your Google account? If so, untick the check box "settings" from sync an after a browser reset, You'll be fine.Or let Malwarebytes remove the thread, for a last time. I had the same issue, with pup's in the preferences file. After above action, the issue has gone. Link to post Share on other sites More sharing options...
John L. Galt Posted June 14, 2014 ID:841775 Share Posted June 14, 2014 I have Chrome synchronizing my account and do not have this problem at all. Link to post Share on other sites More sharing options...
HiltiHome Posted June 14, 2014 ID:841805 Share Posted June 14, 2014 I have Chrome synchronizing my account and do not have this problem at all.Synchronizing is not the root cause.If the preferences file is modified by malware, or pup's, it will be modified from the cloud, over and over again. It took me some time to find out, why the preferences file got modified again and again, although there was no more malware, or pup on my machine.In my case, sweetpage was removed several day before. Just the entry in preferences file was left, and came back again... I don't now how to load up a clean preferences file to Google. Does anybody now, how to the set my local Machine #1 as master for Google? Link to post Share on other sites More sharing options...
Marty112 Posted June 15, 2014 Author ID:841963 Share Posted June 15, 2014 Ok so what I did was that I unchecked sync and reseted chrome to it's default, deleted preferences file, restarted chrome and scan finished clean. Then I started to allow extensions and everything is fine. So you were right about that preferences file beeing modified through cloud but how am I suppose to find source of this?

HiltiHome Posted June 15, 2014 ID:842157 Share Posted June 15, 2014 Mart112, I have no clue how to solve this issue. Myself, i have disabled synchronizing of settings on four machines. I will wait a month or so, and then enable sync for settings again, hoping the cloud will update to my local machines settings file. If not, i quite sync of settings, cause this is the least important thing I need.Important are bookmarks and extensions. Link to post Share on other sites More sharing options...
Marty112 Posted June 16, 2014 Author ID:842229 Share Posted June 16, 2014 I don't think that this will be solved simply by waiting. I'll try to dig out some information about google's sync and if I find something I will let you know. Link to post Share on other sites More sharing options...
HiltiHome Posted June 16, 2014 ID:842411 Share Posted June 16, 2014 I already found out how to: Go to https://www.google.com/settings/chrome/sync delete all synced items.Than connect your clean master machine again to your Goolge account, and your done.

anachromat Posted July 22, 2014 ID:856055 Share Posted July 22, 2014 Just went through this myself. Summarizing what worked: Use the Chrome Sync dashboard to disconnect Chrome and clear the settings on the server:https://www.google.com/settings/chrome/sync And click the "Stop and Clear" button. Close Chrome. Run a Malwarebytes scan. Under Premium, a HyperScan (the fastest) is good enough. When the scan ends. let it quarantine PUP.OPTIONAL.ASK.A. Start Chrome, and sign in to Chrome Sync again. Link to post Share on other sites More sharing options...
