Hi, Pieter. I’m not exactly a newbie, but I am new to spyware prevention. I discovered the world of spyware and adware when my machine became so clogged with pop-ups that it would barely operate on-line. A bit of investigation on the Net led me first to a free scan called PestScan and then to the freeware spyware destroyer SpyBot Search and Destroy. PestScan doesn’t offer free destruction of spyware, but the scan it performs is more thorough than SpyBot’s, and it does offer free instructions on how to destroy pests manually. I loaded SpyBot and used it to destroy pests. I’ve then checked its work by immediately loading IE and using PestScan. PestScan keeps turning up the same two particularly persistent spyware programs, called BookedSpace and Twain-Tech. Sometimes there’s a third one called Adware.Binet, which uses the same CLSIP as BookedSpace. BookedSpace appears a couple of times on SpywareBlaster’s database, but not with the same CLSIPs. Following PestScan’s instructions, I’ve deleted the relevant keys from my machine’s registry every time I’ve seen them (and followed further instructions about deletion of DLL files). But they reload whenever I go on line. Thus it appears that these programs are somehow resident in my IE. Investigating a little further under the subject of “immunization” or “prevention” led me to SpywareBlaster. I’ve followed your procedure for adding custom CLSIPs to SpywareBlaster’s standard list. But it hasn’t worked; BookedSpace and Twain-Tech keep reappearing in PestScan’s sweep of my registry (and indeed their wretched pop-ups persist as well). What am I doing wrong? I have several questions: 1. Should I reboot after adding the custom CLSIPs? 2. The screen whereby one adds a custom CLSIP contains no field for Type. Yet all the CLSIPs shown in SpywareBlaster’s database are identified as either cookies or “ActiveX.” Meanwhile, all the CLSIPs in the little sample screen you’ve shown in your instructions are identified as “Spyware.” What’s ActiveX? Is it a type of spyware? If not, what’s the difference? Could this difference account for the failure of my addition of these custom CLSIPs? 3. If my understanding of what CLSIPs are is correct, they’re those 32-character strings of code which sometimes accompany registry keys. But not all the registry keys PestScan turns up contain CLSIPs. And I have the impression that to rid your machine of spyware, you have to eliminate ALL the relevant registry keys (and sometimes perform other, non-registry-related steps as well). Could SpywareBlaster be failing because it is blocking the loading of those registry keys that contain the prohibited CLSIPs, but not other registry keys which are alone sufficient to load the spyware? 4. SpywareBlaster’s database’s not being in any discernable order makes it terribly difficult to learn whether any given CLSIP is on it. Is it possible to sort it, either by name or (better still) by CLSIP? Alternatively, is there a way to search it for a particular CLSIP? 5. Sometimes when I delete a CLSIP from one registry address, but it exists in another address as well, it’s already gone when I go to look for it in the second address. Is this to be expected? I’m sorry for the great length of this post, but as you see, my situation is somewhat complicated. I really appreciate what you’re doing!
