Add Spybot Search & Destroy (free) to your arsenal, and you should be in great shape.
After uninstalling Spyware Doctor 3.8, due to the problems in the previous threads, I installed Spyware Doctor 4.0, thinking PC Tools have got their act together and have vigorously tested this new version. I was wrong! After installing version 4.0 yesterday, I found I could not get onto the internet, just various error messages popped up. After wasting several hours doing several Anti-Virus and Spyware/Malware scans (All gave clean results)I decided to uninstall version 4.0, and hey presto, my PC was running normal again. I am now just going to use Ewido and Ad-Aware for spyware, as I no longer trust Spyware Doctor. Has anyone else had any problems? I am about to send PC Tools another e mail regarding this.
