I have spent a whole day to determine which antivirus would be the best for my PC. In summary my result is as follow, and i still have some wonderings...: KAV: Great but heavy on CPUand awful interface. I have read that the last beta version is lighter on the CPU with a nice interface. Is it true? AVK: Great because it is using the KAV Motor. But the last version is only in english. Is there any way to get an english version of the AVK? Is it true that, as this version is not that light on the CPU? NOD32: Great because it seems to be light...(not sure because some are telling it to be slow...). And I am not so sure about its efficiency against all viruses and trojans... DRWEB: Great because it is said to be light. Is it really better than NOD32? I don't care the price. I want to be protected, really protected. But I don't want the antivirus to slow down too much my PC And I don't want a too complicated antivirus neither, considering I might propose it to other people with less IT knowledges... So what sloud I choose?
