One thing I noticed is that you have 2 instances of XAMPP installed.
This is not recommended.
Perhaps try renaming the instance that you don't use to say xampp_copy or even delete the other instance.

With regard to the perported attackers, you can block them or any one, from accessing your site by grabbing their IP or domain name from the Apache error or access logs and inserting them into a .htaccess file in the www (Document Root directory where the index file is) of the site they are trying to access.

The Deny directive content in the .htaccess file may look like this:

Deny from 123.45.67.8 <- full IP
Deny from 123.45.67. <- IP range
Deny from 123.45. <- IP range
Deny from 123.45.0.0/16 <- CIDR
Deny from 10.1.0.0/255.255.0.0 <- Network mask pair
Deny from domain.tld <- blocks sub.domain.tld also

There is no limit to the number of IPs or domains you can enter into a .htacess, but it is recommended that each entry be on its own line.

Have you tried the recommendation in the FAQ?
http://www.apachefriends.org/en/faq-xam ... s.html#cpu

Add it as the last line and then restart Apache after implementing it.

Have a look at implementing httpd-mpm.conf in xampp\apache\conf\extras by uncomment the mpm entry in the httpd.conf file. It has ways of upping things.

Also this high cpu usage has been attributed to a firewall issue. Check your firewall if you have one installed. You could momentarily deactivate it, check Apache's cpu usage, then reactivate it if there was no change.
