It seems that the latest batch of AV software is quite inconsistent when it comes to Vista, but it is especially important to secure Vitsa and tie it down in order to take full advantage of all the other high-tech security features built right into Vista.
The only real options for Vista AV are eTrust EZ Antivirus, Trend Micro PC-cillan, and ESET NOD32.
It seems that eTrust and Trend Micro are the only companies taking Vista seriously. Both have offered free trials of their subsribtion, but eTrust gives you a better deal:
You can claim eTrust’s free subscription here, even if you don’t use Windows Vista. EZ Antivirus is a decent product, it is fairly lightweight, fast, and up to date. The subscribtion is for an entire year, and is OS independant.
Trend Micro has been in the game for a long time, but have constantly failed to impress. Their software is not as lightweight as one would like, and tends to bog down the PC after a while, and especially during periods of high disk activity. The trial subscribtion is only until October 2006, and then you’re on your own.
ESET’s NOD32, our long-time favorite AV product for Windows, hasn’t been updated in a while, and has some serious issues with Windows Vista. However, it remains the fastest, most often updated, and lightest solution out there, and so if you still want to give it a try, here’s our guide to getting NOD32 running on Vista, and here’s a link to a 30-day trial if you don’t already have a license.
