Avast is mostly known for its powerful, free internet security solutions, but even free users admit that the only way to achieve utmost protection is by upgrading to more specialized apps. Unfortunately, Avast Security for Mac is a bit overpriced compared to its list of features, which could be discouraging for many users. Thankfully, the software’s base prices can be easily reduced by opting for a longer renewal period for your license. However, the best way to save big on Avast – up to 83% to be exact – is by purchasing licenses in bulk.
