I have a pentium 350 MHz , 64Mb , 8Gb disk Win '98 SE . Lately after booting up , I hear a lot of disk action after the Windows main screen , and it takes quite a while until I can start working . The McAfee says there is no virus , I've done a defrag/maintenance etc. , have tried to remove any AdWare and even disabled the McAfee system scan . Have also checked the WD disk with their Data Life Guard programs and it reports no errors . Any ideas on this ?
