Advice Please

Hello to all members of bitdefender forums :rolleyes: just joined having installed the premium edition on my ageing old thinkpad laptop! I recently abandoned avg pro 7.5 and avg anti spyware in favour of bit defender , I would appreciate some advice from you more experienced users of bit defender, I used to use avg anti spy software to remove malware , and or spybot search and destroy until the recent new versions were brought out, I have always had two minimum programs to scan my pc the idea being if one program misses something the other will pick it up , What if any othe software can I or have others found will work happily alongside bit defender without conflicts or is the antispyware rootkit protection provided by bitdefender enough on its own thanks
