I have been using Bitdefender for a long time now and now I am planning to switch to Eset, as Bitdefender is making my pc so slow that it's annoying. I researched quite a lot lately about it and I found out that according to AV independent lab test scores, Bitdefender is a bit better in terms of malware protection and system impact than Eset. But it seems Bitdefender still puts some impact on system. Please, let me know what are your thoughts on it. And is it a good idea to run both at the same time?
