Dr.Web Security Space Review
Not only does Dr. Web Security Space detect viruses and other malware, but it also includes malware removal and repair tools which help you fix an infected computer. On the downside, the virus scanning tool is slower than those provided by other anti-virus products and uses a lot more computer memory (RAM).
If you have a relatively fast computer, the slow speed and high memory use won't affect you much and you'll get the complete suite of Dr. Web tools---anti-virus, firewall, malware removal, anti-spam, parental controls, and more. Few other home security suites contain a complete set of tools in a single product.
