I use Bitdefender now for a couple of days and had only 1 reboot required. A reboot can be important. Maybe it is necessary against cracks for example. Dunno. I had only 1. And i use the Bitdefender Total Security 90 day trial. ;=)
Bitdefender software was the only antivirus software from all 21 firms tested to catch 100% of the malware thrown at it in the April 2013 Real World Protection Test by AV-Comparatives, the independent global antivirus testing organisation. The test – recognized by outside authorities as the organization’s most complex and comprehensive – drew competitors including Kaspersky, AVG, McAfee, Trend Micro and others.
