Question: Does this run on Windows 8.1?  This is the update that Microsoft release to Windows 8
Document: I've read much more positive things on the internet about Kaspersky than other anti-virus programs so I chose it over others. I'm not disappointed. Running Windows 8.1 on an older, slightly underpowered Intel based low-voltage 1.5Ghz processor, the program installed without a hitch.This program just seems invisible which is absolutely a big plus. After an update and scan I seem to be virus free and fully expect Kaspersky to keep me that way.
I have a brand new PC with windows 8.1 and this prog will not run. The Amazon product description says it works with Windows 8 (see below), but says nothing about compatibility with Windows 8.1. I want to return it and get my money back or find a version that works.System RequirementsPlatform:  Windows 8 / 7 / Vista / XP
I've used several anti-virus systems in my time:  McAfee, Symantec, Norton and ESET. All of these have let me down at some point. Kaspersky has the best overall protection available, finding and removing the most threats. However, I have three main issues with this latest version:1. Too much clicking to do things that should require one click or should otherwise be automated.2. Compatibility with Windows 8.1 has been a disaster.3.
all run very slowly. I installed it on another desktop computer with the same results. Becaise fo the decrease in response time on the two desktops, I did not load it on my laptop which uses Microsoft Windows 7. I continue to use Microsoft Essentials on my laptop and it has not had an decrease in speed. Probably a good product but computer speed did decrease for me. on the tow computers I installed the program on.
Also, keep in mind that this is a ****3 USER LICENSE**** meaning you can use it on three Microsoft Windows machines, so it becomes an even better deal in knowing that. Seven dollars a seat isn't bad at all and most people I know, especially families, have more than one machine in the house anyhow.
The product was advertised as Kaspersky Anti-virris 2014. I received Kaspersky Anti-Viris 2013 (June, 2013 version). l updated it which took sometime but it is current on updates. I have Microsfoft XP operating system so had to install an anti viris program as Microsoft no longer supports Microsoft Essentials on XP systems. Since installing Kaspersky I have run several full scans and have not detected any viris. I find my computer runs at less than half the previous speed.
I am using this antivirus on a couple of window 8 computers. Windows 8 has windows defender on it but they recommend and base antivirus to take care of viruses. So far it has done it job.
I've found this to be good protection; I've had no issues with it. Windows 8 can be a bit fussy with it, though (but Windows 8 can be fussy with many things).I don't prefer this to Norton, necessarily, but I don't dislike it.
I have it set up to update at 11pm each night and run a full scan at 12:30am (remember the huge/slow updates?). Neither execute whether the computer is being used or asleep (supposedly it will run while your computer is asleep if you select that option, which I did).Because I didn't have to pay for this I'm giving it four stars, if I had to pay for it I would only give it three.
I installed this on my husband's new laptop with Windows 8 OS only a few days ago when his Norton Anti-virus was about to expire. It was a very slow process for which I deduct one star. The download page kept saying it would only take 10 minutes but it was almost 2 hours before the program was fully loaded and that was before the updating process.
Answer: Yes
