I read 16 pages of complaints about services not responding and the alleged "fix". I have uninstalled all other anti spyware software. This is really frustrating because we purchase 10 user licenses and between the non responding, the cpu hogging, and generally slow internet and computer speed in general, bit defender has been a huge disappointment. Now I'm supposed to buy 2011 when Panda worked great for us last year? Please. The only way we'll use 2011 is if it is free.
