With beta version do You mean 2018 version or...? where did You download from?
What do You mean with high CPU? in general K2017 was not so bad even in old systems, and I think 2018 is even lighter, could You please share Your hardware specs, Windows version and other security tools installed in Your system?
Yes, the 2018 version, v126.96.36.1995, which I downloaded from Softpedia.
The very high CPU is when I'm running a scan. It stays at around 80 to 90%. The computer is running Windows 7, 64 bit on a system with a Core 2 Duo T7200 CPU, and I have no other security software installed. It's not the fastest of processors, but, in comparison, I installed Panda Global Protection after uninstalling Kaspersky, and CPU did not go much over around 25% when scanning.
That's so strange, here using KTS2018b in an Intel T4300@2'10Ghz + 4GB RAM + W10CU Pro x64 + SSD Sansumg EVO 250GB, and not getting by far so high while a selective scan (here as maximum about 63% of CPU) and having Security set yo High for Scans...
Did You tweak something in K2018?
In Performance Settings try to enable -> Postpone computer scans tasks... (I have it disabled)
downloaded kaspersky total security 2018 some weeks ago and run it in trial mode for just over 3 weeks after which I entered my purchased serial number for the 2017 version which was accepted straight away just over 2 weeks ago. It is running faultlessly and isn't hogging my pc's resources anymore than pretty much any other modern security suite, in fact it feels pretty snappy even on a low spec pc compared to other that I recently tested. There are some worthwhile upgrades compared to the 2017 version and can't see any downside in upgrading now. The following link is still valid and is the one I used: Kaspersky Internet Security 2018 188.8.131.525 - Download the latest freeware, shareware and trial software - Downloadcrew
and you will see on the download info that it is indeed the "final" version and not the beta version. Hope this helps. steve
Kaspersky Internet Security 2018 provides the following new features:
Added notification from Web Anti-Virus regarding pages containing adware or legitimate software that can be used by criminals to damage your computer or personal data.
There is now protection against infection while the operating system is being restarted.
There is now the capability to navigate from the Licensing window to the My Kaspersky portal to view information about the activation code.
You can now add a new activation code if the license has expired.
There is now a user-defined list of domains for which connections are not controlled by the application.
Improved technology for counteracting the modification of user files by malware, particularly by encryptors.
Diagnostics of application installation issues have been improved. Now, when there is a problem with application installation, the application saves the installation logs instead of deleting them.
Application Self-Defense during upgrade to a new version has been improved. Now there is protection for not only the current version but also for the newly installed application prior to it being started for the first time.
Improved speed for certain installation scenarios, the first startup, and the first update of the application.
Improved notification that appears if you disable the System Watcher component. The notification now contains a more detailed description of the consequences of disabling the component, especially regarding the resultant lack of protection against encryptors.
The procedure for displaying notifications has been improved.
The application now waits a longer amount of time before displaying a notification about outdated databases and application modules when the computer wakes from sleep mode.
MAIN KNOWN ISSUES
If the "Always scan encrypted connections" check box is selected, the application will scan encrypted connections even if you have paused protection.
If the application was installed together with Kaspersky Password Manager and its active plug-in, the Internet Explorer browser does not display the On-Screen Keyboard quick launch icon in the login and password fields. You can open the On-Screen Keyboard by pressing the key combination CTRL+ALT+SHIFT+P.
If the application was installed over one of the previous versions, part of the managed applications may disappear from the list in Parental Control settings.
After you enable the Anti-Banner component, banners on pages that are already opened in your browser are not blocked until you refresh the pages.
If the application was installed in Windows 7 and you upgraded the operating system to Windows 10 but now want to revert back to Windows 7, you are advised to uninstall the application and install it again after reverting back to Windows 7.
On certain websites, the application may block the download of additional pages in pop-up windows or frames. To resolve this issue, clear the "Inject script into web traffic to interact with web pages" check box in the network settings of the application.
If the application was installed on one of the previous versions, Trusted Applications mode is disabled by default even if it was enabled in the previous version.
If interactive protection is disabled, tasks for processing threats on your computer from the My Kaspersky portal might not be performed.
Certain types of objects from the category “Legitimate software that can be used by criminals to damage your computer or personal data" are not processed from the My Kaspersky portal. These threats must be processed on the computer.
If Microsoft Edge cannot switch to Protected Browser mode, the application starts a different browser installed on your computer in this mode.
I was a Kaspersky user in 2014 and 2015, an awesome program then i changed but i don't remember why, maybe the price. For last 2 years i used Avira but not a very good experience like KIS. Now i come back again and i'm very satisfied as in the past. Light on pc performance, light file installation, fast real time protecion. Imho the best.
