Other advice: Paid versions of Malwarebytes conflict with AVG, you should only use Malwarebytes Free for supplementary scanning.
Checked FAQ and other repositories, didn't find info about what AVG files can be registered as exceptions to Malwarebytes.
Malwarebytes has started using up to 100% CPU on an XP SP3 system. Malwarebytes advice is to make sure that both anti-virus, firewall, and malwarebytes know about each others file that can be excluded from scans. Malwarebytes offers a list of their files that can be excluded, and I did that. Looking for an equivalent list of AVG files that malwarebytes can exclude.
... Or, other advice, of course, about what may be causing the enormous slow-downs I've been experiencing over the past several months.
Thanks!
