Net Protector is a good antivirus software where we can scan the files and it cleans immediately the affected files. Installation of this software is also easy. Just insert the disk and press installation, then it will ask for key, which is on the inside of package cover. Later it will ask your details, fill the disk and press installation. Turn on the data and it will take some time to install. Then you can use that software. It asks daily to update, it will be nearly 1mb. By this software we can our PC and other connected devices. It also provides Net Protection facility also. You need to renew this software every year. But it takes a long time to scan. It took nearly 6 hours to scan my PC. That is the only demerit of this software.
