I need your expert opinion. I'm now using paid version of "Webroot Spy Sweeper", aso Free version of "SpywareBlaster" and "Windows Defender".  Spy Sweeper subscription is about to run out. My question : Do I really need Spy Sweeper if I have the other 2 free version running on my computer? I'm also using the free version of Avast for my Anti Virus protection. I use MBAM and Super Anti spyware for periodic scanners. I have never had a problem with spyware. Once in awhile I will catch something with my periodic scanners. The "Webroot Spy Sweeper" works great, but do I really need to continue the paid version of spyware? Thanks.
