*doubleclick* *atdmt* *serving-sys* *bs.serving-sys*

by junjie86 / April 16, 2010 8:49 PM PDT

Hi everyone,

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!

Such Tracking Cookies Will Continue To Return
by Grif Thomas Forum moderator / April 17, 2010 5:59 AM PDT

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.

VID voltage range

Thank you Grif! Yeps i have given up on trying to remove those pesky cookies as they shouldnt be the root cause of my com's slowdowns and doubleclickings.

One thing i noticed on my laptop is that during com slowdowns and 100% cpu usage, the core VID voltage can drop to about 0.85V which is odd cos according to intel the VID voltage range of core duo T7500 is supposed to be at 1.075V - 1.250V. I guess when the voltage drops to 0.85V, the clock speed drops to about 400 MHz from the usual 2200 MHz when the voltage is at 1.250V. Is there any reason why the voltage will drop to 0.85V?

On doblelicking with mouse

I right click and then open [one click] I also use ccleaner from www.piriform.com. It does say somewhere where you can elect to single
click or double click. Also, under Internet Options, under the Advanced you can have all temporary files removed if you shut down under security. If you go to properties, there is delete all cookies, delete temporary internet files and I have set History from 20 days to 0 days. Also, you may need to clean out your fans. Darrell

Voltage Shouldn't Drop...
by Grif Thomas Forum moderator / April 17, 2010 2:05 PM PDT

...and the usual cause is a failing power supply or other hardware short or failure.. The problem with a laptop is those items. excepting maybe a hard drive or possibly RAM can't be easily switched out to test..

It's your choice where to proceed from here.

Hope this helps.

Regarding Tracking Cookies....
by tobeach / April 18, 2010 2:57 PM PDT

Since you're using Firefox (I assume as your main browser) you can add "NoScript" freeware program to FF. This will allow you to block those cookies from each site individually. Also it will display (w/ click of icon)a list of every cookie script wanting to run where you can allow, allow temporarily for this visit or deny access always.
I believe this is the simplest & cheapest way to UP the security/privacy
on Mozilla browsing. I'd hate to go back to not having it!! Happy
