AVG Internet Security
AVG Internet Security 2015 is a powerful antivirus, an essential tool that protects your computer against viruses, worms, trojans, rootkits, and other spyware when browsing online or going through email.
The scanning engine is quick and powerful, and updates are performed daily. Scanning speed has been reduced thanks to the priority system that optimizes resource consumption: scans are put on high priority when you're away from your computer, and low priority when you're using it.
With AVG Internet Security 2015, you can also schedule virus scans ahead of time and choose which parts of the system you need to analyze, as well as run separate scans to identify rootkits.
