Sony Vaio with XP Home on AMD4 1Ghz system freezes with svchost.exe using 100% CPU at various times including whenever the internet connection program opens the modem port. Suggestions?
Additional, perhaps relevant history- The system initially began freezing after downloading MS critical updates. After several hard reboots, the system began continuously rebooting and had to be restored with the recovery disks including reinstalling the OS.
After web connection and download of updated virus protection files from Trend Micro for PCCillin 2000, a scan detected MS_Blast.a, MS_Blast.e, and Nachi.a viruses?!? I downloaded the security patches and MSBlast repair and the viruses (apparently) have been removed/repaired. However, the svchost.exe using 100% and freezing system problem remains.
