Hsremove 2.38 - Does N't Work !

I use Windows xp.
At first I ran the program without going to safe mode (having not noticed the instructions) and it worked but it lasted only one hour.
I repeated the procedure, this time from safe mode and with internet connection off and the program reported "15 items removed".
Unfortunately upon rebooting the machine it lasted for only one session of IE.
When you close it and open it again, "home search" reappears.
The instruction [3] re. network security appears to be imprecise.
What can I do now ?
Does the virus develop an immunity after the first unsuccesful attempt ?

It is extremely malicious. Why would a simple-to-remove adware not suit their purposes ?
