First of all, I like the interface, and I've read the story behind the similarity in appearance to Giant/MS Antispyware, so I expected the same interface anyway.

But there's more bad than good: be aware that CounterSpy will disable Giant/Microsoft Antispyware without warning. Immediately after installing CounterSpy, Giant/MS Antispyware was unable to update or connect to the internet. Upon rebooting, CounterSpy locked my XPSP2 system up hard upon reaching the Desktop. A hard boot had no effect on the lockup. It took 2 hours of work, including booting into Safe Mode (to remove CounterSpy and rename the Giant/MS Antispyware directory temporarily) to get out of the hole that CounterSpy had dug.

Now, before you jump to any conclusions about my computer skills, I am a software & hardware professional that beta tests both software and hardware daily. I work & program on computers 12 hours a day, so I see the good, the bad, and the ugly. CounterSpy falls into the "ugly" category. Had I not known how to recover, my system would now be unusable.

Based on my experience with CounterSpy, I do not recommend it to anybody. Had CounterSpy warned me about to remove Giant/MS Antispyware prior to installation, it would have saved me 2 hours of repair work. There is no reason such buggy software should be released to the public.

Hope this helps others avoid a few hours of repair work due to CounterSpy.
