Ok out of nowhere, no programs running my computers light began to blick when its "thinking". No progs are running and havent for a while (10mins). So I open the task manager and the page file memory is low ( thats good) but cpu usage is fluxing between 20% and 80%. then i go to processes and mcaffe is using an unusual ammount. so I unistall and restart it (i have avgfree wich is 1000times better) then all is god for about 2 mins then I open task manager again and SVCHOST.exe is taking more and more memory. starts at 7000 then goes to over 40000. and its still doing it as of now. Though, i have automatic windows updates enables but i havent given it the OK to install them. Also I have WinXP Dell Dimension 2400, 256mb ram P4 2.6ghz or something around there. PLease help its driving me crazy and running my apps Ultra slow.
