The best antivirus!!! If You are looking for real security then Bitdefender is choice!
I have on PC installed Bitdefender Internet Security 2013, it's really best antivirus I ever had. Before I had NOD32, Kaspersky, but now with Bitdefender I'm fully satisfied and that will be my only choice for future. When I tested it, for example firewall at www.pcflank.com without problems I pass the quick test! This antivirus solution really catches the virus on fly, like a flash, without doubt, the best! Also on my Android phone I have almost all applications which comes from Bitdefender, I purchased the Mobile Security and have a very little or almost zero impact on my battery, but I have a trust for this company that I'm secured. Clueful, another useful application for saving privacy, then PowerTune up, a must have application for battery saving and for cleaning the junk files and cache. Also tried many others battery saver applications but found this is the best solution for me. Keep up the good work Bitdefender, and all the best in the future!
