I am an IT professional and for efficient working on my laptop, I had need to get the best antivirus software which doesn't slow down my system.
Then one of my friend suggested me to buy Protegent complete security software which comes with inbuilt data recovery software.
I was surprise to know the various features provided my this antivirus software and works on the system with RAM 512 mb also.
The features which this antivirus provides are very beneficial:
Protegent Total Security
Crash Proof
Port Locker
