AVG Antivirus has been an up and coming virus scanner for many years. Its free version is one of the most downloaded files on the Internet in the Computer Security sector. The new interface is clean and intuitive while still remaining useful.
AVG went through a rewrite of their virus scanning engine and included two of their stand alone products with AVG Antivirus as well. AVG Antispyware and AVG Antirootkit were both integrated with the virus scanner. Also revamped was the way AVG Antivirus uses the hardware within your computer. It was changed to make better use of the multiple cores which are common in todays computers. This should speed up scanning as well as reduce slowdowns.
