The virus landscape has also changed; viruses that used to be annoying pranks have evolved into pernicious threats capable of not only destroying your computer, but stealing your information and identity.
The benefits of installing a basic security solution on your PC are obvious, but the cost in system slowdown used to make it tough to bear. Luckily, modern antivirus software haven’t just improved their level of protection, they’ve significantly improved resource efficiency and overall speed. You can have ultimate protection without giving up your resources. With advanced technologies and straightforward usability, antivirus software is more effective than ever, and doesn’t require constant maintenance from you. Say goodbye to annoying security warnings and noticeable slowdown; current antivirus programs deliver constant protection and can actually speed up your computer.
The last generation of antivirus software brought advanced heuristic detection into the mix. Continuing to improve, the 2011 lineup of antivirus products often incorporate further developed proactive protection with better behavior checking and even file reputation analysis. Several of the software incorporate ‘in the cloud’ security and other advanced technologies to increase safety and convenience. From gamer modes, to battery saving settings, to integrated web link scanners; antivirus applications are more versatile and have upped the ante for features and functionality.
