    I will post HJT log but I have cleaned registry several times and run Ad-aware and Spybot and eliminated all infected files to where CWShredder says my system is clean. In fact, when CWShredder said my system was clean, running Ad-aware showed two more registry files infected with CoolWebSearch trojan and I eliminated these. Then suddenly, (whether it's because of a reboot or an internet session with IE, I haven't been able to determine) the same registry files become infected again . It has to do with the HOMEOldSP file. The start page, search page, etc. have some obxcure .dll file but the HOMEOldSP always comes back in the registry as the same. The Ad-aware says these are all CoolWebSearch infections. Something is hiding which is not being cleaned up by anything I run, but it is re-infecting my system with the CoolWebSearch trojan over and over. So far, no one has been able to help me in several forums to which I have posted.

    Any new ideas would be most welcome.

    By the way, my registry AppInit_Dlls value does not say "hidden value=0000 00 00"; it says 0000. I tried to change it by right clicking "Modify Binary Data", but I couldn't make any edits of the 0000.

    you need to turn off system restore or they'll keep returning. post another hijack this log after deleting them using adaware and turn off system restore.

    Yes, I had System Restore turned off. My system may have been fixed. I've gone a day without the infected files returning.

    You will have to wait until you get hijacked again and then post your log.
    The log above will be percieved as being clean,which it is.........but these files hide from most attempts to find them.

    Yes; I have posted infected logs and followed instruction on which files to apply the HJT "checked fix" and then used CWShredder and then Ad-aware. But there is nothing in the infected HJT logs that is "visible" either; other than the known changes to the IE\Main registry files Start Page, Search Page, and the infamous HOMEOldSP file. Believe me, I have been to other forums and have applied all of the "fixes", but nothing so far has prevented the CWS from returning to reinfect the standard IE\Main registry files. It's as if the CWS invaders have a direct line to my computer and can send the signal to reinfect at any time I an connected to the internet :mad: .
