I only found out about SpywareBlaster today. I downloaded the 5.0 version and installed it on my computer. After installing the program it did not start. I checked the task manager and saw two instances of it running there. But no gui on my screen. I killed the processes then uninstalled it and tried again. Same problem. I am running Windows Defender anti virus. So I uninstalled SpywareBlaster again. Then stopped Windows Defender, rebooted my machine and reinstalled SpywareBlaster. And the same problem still. I can see two processes of SpywareBlaster running in task manager but no gui running. I found a thread from March that talked about a similar problem but could not post to that thread. https://www.wilderssecurity.com/showthread.php?t=338577 Sounds similar to the problem talked about in March on the last comment. Any ideas? Thanks.
