I have two cookies in my Temporary Internet Files that are acting unusually, and cannot be removed.
These are cookie:email@example.com/ and cookie:firstname.lastname@example.org/.
I know that questions about yieldmanager are common, but I think that this one is unusual. Hence a new thread. I have tried deleting the cookies manually, and also deleting browsing history, and also opting out of yieldmanager cookies, also blocking cookies, and also using Task Manager, and also System Restore. These two new cookies were not affected by those actions.
My two questions are:
1) Why will they not allow themselves to be deleted as in the past?
2) Is there some way that I could delete them?
I am on XP. I use Internet Explorer.
I use the AVG free version. I run AVG regularly. I have also run it only on the Temporary Internet Files folder. These two new cookies are not affected by this action.
Delete Browsing History:
Also: normal practice for me when closing down is to go to Tools/Internet Options/General/Browsing History/Delete … and choose Temporary Internet Files, Cookies and History. This normally knocks out the ubiquitous yieldmanager cookies. These two new cookies were not affected by that action. All other cookies reacted appropriately.
Delete Cookies manually:
Also: I occasionally go to C:\Documents and Settings\Owner\Local Settings\Temporary Internet Files and manually remove anything there (also C:\Documents and Settings\Owner\Local Settings\History and C:\Documents and Settings\Owner\Local Settings\Temp and C:\Documents and Settings\Owner\Cookies – these folders are clean). These two new cookies were unaffected by that action. All other cookies reacted appropriately. (In the past, sometimes cookies refused to be deleted until I had left the Temporary Internet Files and then, after I had gone back into it, after which they suddenly consented to being deleted – this was normal, I think).
Also: since these two cookies have appeared, I have also opted out of yieldmanager cookies at http://ad.yieldmanager.com/opt-out. This has had no effect, and I have since deleted cookies again, meaning that this opt-out request is no longer valid (one has to leave a new cookie in there in order for this request to remain valid). These two new cookies were unaffected by that action.
Also: I have gone into Tools, Internet Options, Privacy, and blocked the sites fastclick.com, fastclick.net, yieldmanager.com and yieldmanager.net. These two new cookies were unaffected by that action.
Command prompt/Task Manager:
Also, I have opened a command-prompt window and left it open. Then I opened Task Manager and chose "end process" for explorer.exe under 'Processes'. I left the Task Manager open. Then, in the command-prompt window, I changed to the folder where the cookies are (C:\Documents and Settings\Owner\Local Settings\Temporary Internet Files\). I typed DEL *.*. Then, back in Task Manager, I chose File New Task, and typed explorer.exe and clicked 'OK'. These two new cookies were unaffected by that action. All other cookies reacted appropriately.
Override automatic cookies handling:
Also: I have gone to Tools, Internet Options, Privacy, Advanced, then checked Override automatic cookies handling and at First-party Cookies checked Accept and at Third-party Cookies checked Block, clicked OK, clicked Apply and then OK. I did this twice, the second time blocking first party cookies as well. These two new cookies were unaffected by these actions.
System Restore (incl. Safe Mode):
Also: I have tried System Restore, which was unsuccessful. Then I tried it in Safe Mode. It was successful. But these two new cookies were unaffected by that action, possibly because I did not go back to an early enough date. I then tried System Restore in Safe Mode again, to search for an earlier date. System Restore begins operating (i.e. files slowly being restored), but collapses half way through, putting me back into normal operating mode, with a message telling me that the restore couldn’t be done. I will not disable my System Restore until I know better.
The cookies are not giving me unnecessary advertisements, but are very unusual in that they will not get knocked out using well-tried and successful methods in the past. And I don’t like the way my system restore might be being affected by them, or perhaps something else.
I do not like doing banking on my computer when there are things on the Internet there that communicate data to others, and which I did not put there. Especially things that are behaving unusually (i.e. not allowing themselves to be deleted), even if this behaviour is having no other observable effects. I always clean up before I start banking.
I would appreciate help on this one.
