Help! I need a new anti-virus scanning software! My current software is outdated and needs to be renewed, but I find it too costly. I know that there are free anti-virus softwares available in the internet. Can someone please suggest me the best anti-virus software available today? Is it safe to download these anti-virus softwares from these sites? I need an anti-virus software that can detect and get rid of Trojan virus. I hope someone could make a good recommendation.
