Installation. If you have Vista, the CD requires that you download the software; for other platforms, you can choose installation by CD or download. I have installed it to XP computers using the download version. I would welcome full CD-based installation for all platforms since that’s what I would do for a computer that I suspected was infected. After the full download, the installer checks for incompatible programs, which you must uninstall before continuing.

I bought it and messed up every computer it was on. I called and they said that I had to pay $150 to $175 more to get it fixed.

I don’t know if they have changed this software recently, and the great reviews people are giving are based off an earlier version that was much better, or if the reviews are fake. But I do know for sure, this free 2015 software is crap!! If there was a zero star I would give it that! So, I wasn’t expecting much given the fact that it is free, but it was much worse than even my really low expectations.

Gets the job done with out slowing my computer too much. Decent price, so I have continued with this brand. Very easy to use and navigate. System scans do take FOREVER though. Much longer than in previous Kaspersky versions. I just start the scan before I go to bed, that way I’m not waiting on it and getting annoyed. For me they regularly take 9 hours or so for a full system scan, where as in previous versions I remember them taking 2, maybe 3 maximum.

Slows down computer but does its job.

Never seemed worth the money, and never did find/ prevent any viruses even though my computer ended up getting one.
