Hi,
PurityScan is Advertising ware.
Here is a link with full explanation:
http://www.doxdesk.com/parasite/PurityScan.html
It is supposed to remove porn advertising ware, but according to the above site, doesn't do it. It adds more advertising files and registry entries.
Please try all the following to get rid of it, and I have also suggested ways to run these scans:
If you think you already have Spyware/Advertising Ware in your computer, run these as follows:
http://www.security-related.com/download2.htm
Download: SpyBot Search & Destroy; 1.3
(If you use the Spyware Blaster free program, then don't set SpyBot to the Immunization feature)
AdAware at:
http://www.lavasoftusa.com
Download: AdAware_SE
CWShredder at:
http://www.intermute.com/products/cwshredder.html
(CWShredder is intended only for removal of CoolWebSearch files; placed as spyware on the harddrive). It is not a "stand alone" scan, but needs to be run. Download the free version by clicking on "Download stand alone version of CW Shredder".
All 3 of the above programs run better and much faster when run in SafeMode.
To get into SafeMode:
Re-boot the computer, and immediately after starting up, Press and hold down, F8, at top of keypad.
When the options show on the screen, use the up and down arrow keys on the keyboard to select
"Safe Mode".
Press Enter
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. Then, run CWShredder.
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.
If you wish to have a great program, after you clean out Spyware/Advertising Ware:
SpyWare Blaster 3.3

The Spyware Blaster is the best I have found for keeping stuff out of the computer; it stops it before it can get in.
I also use Win98SE; and if you wish to have a listing of Maintenance Steps for 98SE, which keep the computer running smoothly, either post back or send me a private message.
Best wishes, and best of luck,
