The totally free version of avast is known as a hugely outstanding package that covers each of the bases and does so with convenience. Its user interface uses blue tones and orange decorations (from the company’s logo) to highlight essential features, plus the ‘Smart Scan’ button around the left-hand menu gives you a simple overview of every one of the suite’s tools. However , it’s a slight pity that after the program identifies advanced problems, clicking ‘Resolve all’ automatically takes you to a purchase page, encouraging you to pay for Avast Premium Protection. This sort of upselling is commonplace with no cost antivirus program, but it may deter from the overall experience. We all also found the program optimisation tools slightly hard to locate. Nonetheless, you can always convert them away if you don’t require them.
