Hi,
It's Spyware/Advertising ware programs.
Here are steps to get rid of it:
If you have the following programs; run them as below.
Spyware/Advertising ware removal
http://www.security-related.com/download2.htm
Download: SpyBot Search & Destroy; 1.3
AdAware at:
www.lavasoftusa.com
Download: AdAware_SE
Both the above programs run better and much faster when run in SafeMode.
It's best to run the AdAware scan first; 3 times; then re-boot.
Then, run the AdAware scan again 3 times; then run the SpyBot.
Re- Boot.
Reason for running so many times:
Some of these trojans' files can be deleted the first time; leaving some others; but on re-boot, they re-write the files that were deleted.
Running multiple times deletes most of it the first time.
Also, if you notice the little green computer lights that show your dial-up connection to the internet staying on when they shouldn't be, located on the bottom right of the system tray, disconnect immediately and run AdAware. These lights staying on means that some URL is sending or receiving spyware/advertising ware to or from your computer, most of the time.
Please run AdAware as described above.
If any problems, please post back.
Merry Christmas,
