Kaspersky Antivirus - High CPU Usage: I know someone who has a Windows XP Pro 32 bit PC (4 GB RAM). He reports that the Windows Task Manager shows that a Kaspersky Process is consuming at or near 100% of the CPU. He has to sometimes disable Kaspersky to do things such as download a file. What could be causing this high CPU usage? What are some suggested steps for further investigation into the cause(s) of this problem? He has 130 days left on his Kaspersky AV. I suggested that he should consider switching to an AV with lower Resourse Usage and install and start using Sandboxie to make up for any possible downgrade in Malware protection that may result from switching AV's. What are some suggested "low to moderate resource usage" AV's that still give a decent level of protection? Note: I am not asking for "A versus B". I would just like some suggestions. Thanks in Advance.
