Try free first
Before you start shelling out hard-earned cash on buying an anti-virus, we suggest trying out free anti-virus programs first, like Avira Anti-Vir or AVG Anti-Virus. Free anti-virus programs are recommended for casual users who don’t upload or download a lot of data.
Of course, anti-virus programs you pay for still offer a lot more protection, but sometimes you can do with just the bare minimum, especially if you don’t do a lot of file transfers.
Besides the programs mentioned above, you can always search for the best free anti-virus programs on the internet, and read reviews on the performance of each. There are also online virus scanners that you can go to, which can scan your computer without you needing to download a file or pay a cent. Of course, this will entail a faster internet connection for it to perform a faster scan.
