If you block them correctly, such as listing them in the "Restricted" sites zone of Internet Explorer, or possibly adding them to your HOSTS file, or something similar, they should stay gone but I wouldn't worry too much about them.. Yes, they are tracking cookies but they're not causing the problem with your mouse double clicking.. I'd try a new mouse PLUS try following the steps in the link below to clean the junk out of your computer and speed things up a bit.
Hope this helps.
Recently (the past 2 months), I have noticed a significant slowdown on the performance of my laptop. My laptop's processor is an intel core duo2 T7500 but sometimes when I open applications such as firefox, the CPU usage hits 100% and it becomes extremely laggy. Also there was another problem that when I single left click on my mouse, there will be random times where a single click results in a double click.
With all these problems, I decided to run a full system scan using McAfee which found nothing wrong with my system, and Ad-aware which found a win32 trojan and a few tracking cookies which were removed.
The odd thing was that, there were a few cookies called *doubleclick* which made me wonder if they have anything to do with the random doubleclicking i am experiencing. I know these are tracking cookies so they should not affect how the mouse responds to my clicking but its still kinda odd. However after removing the *doubleclick* cookies, my mouse still randomly doubleclicks as before. Any1 knows anything about this?
Another issue that I am facing is that the cookies i deleted keep coming back! their names are *atdmt*, *bs.serving-sys* and *serving-sys*. Even though i have specifically blocked these sites from tools > options > privacy > accept cookies from sites > acceptions in firefox, they still come back after I restart my system. Anyone knows the solution for this problem?
Thanks in advance!
