A virus scanner should ensure me that the harmful stuff stays outside, the system's performance but this takes as little as possible to complete. Price is also the face of many free variants in Netzt one aspect.
I got myself this scanner to not very great experience with Kaspersky last year and am very content.
The installation went very smoothly and the system remains fast (for me the installation went flawlessly when I deselected the immediate update of virus databases during installation menu - which you can then catch up after installation immediately and without problems ...).
The scanner works properly, the way the whole system is monitored and you get immediately informed that for Windows again a "critical update" is available (these are usually vulnerabilities that are stuffed). The Windows Update is the same conveniently performed while Bitdefender.
The firewall makes a good impression. So far there were no problems, also programs like online games has been correctly identified with me and without my help got access on WWW.
Included is also a special security tool for online banking with virtual keyboard.
Oh yes, after having installed the program immediately found two malicious programs which Kaspersky has not been found.
