They are both run on clean installs (XP PRO SP2 fully patched) and with Spysweeper 4.5 in recommended setting.
Here is the conclusion: Kaspersky (as we all now) does offer slightly better protection, but it comes at a terrible prize:
Unacceptable amount of STOP ERRORS both running and during BOOT (2-5 per day)
KAS6.0 performing better than KIS6.0 in that regard
Update problems (server overloads)
Hotfixes (should probably still be in BETA)
Slow and painfull wait for scans
General computer instability and freeze-ups
Extreme prizing
My advise folks, GO WITH AVAST!!
This AV works flawlessly and with such ease on CPU ressources!!
Don’t even be tempted to try out Kaspersky, - it will be the beginning of a painful encounter ultimately ending in an uninstall … mark my words
Sorry, my mistake Tech!
This was badly put.
The statement is supposed to be ironical. When one reads the reviews on different forums, general public and review centers always seem to favour Kaspersky over any other AV. This might be the case (I am not an expert on vira) but the truth of the matter is that Kaspersky it too buggy, too unstable, too expensive and too resource consuming!!! … And this is KAS running on a clean install!!!
Hell, it is easy enough to make the perfect AV, just have it block all service ports ;D (if you know what I mean)
Anyway, as I mentioned in my other post - KAS=TROUBLE.
My own experience with KAV6 is very different from yours. I have not used Avast Pro so will not attempt to compare, although there is not quarrel as to the detection rates.
I have used KAV6 since before it came out of Beta. It runs well on my system without conflicts, uses fewer resources than any other AV I have tried, scans in less time - 2 minutes to 16 minutes for a complete system scan, and in general I like it better than anything I have used including Bit Defender, NOD32, Avast Home, and AVG.
I am not wedded to any software, but use what suits my purpose and system better.
If anyone is looking for an AV, they should trial KAV6, NOD32, and a few others including Avast. But your experience is not normal, and your assessment is inaccurate as a general statement.
