Hello. Lately, I've been growing more and more concerned over the slowness of my PC- it takes longer to boot up when it's been turned off than it used to, and programs take longer to open. It all seems realted to when the CPU Usage reported in Task Manager is up to 100%, which it is quite often lately, or the PF Usage, which is also often high.
Online speeds aren't any different, in fact since Firefox was updated recently they almost seem faster, but - if a site with lots of traffic or a page with many images, say, are trying to load, the browser might hang, or, AOL will say it's Re-connecting, and sometimes it signs off entirely. I cannot currently load videos because activating their loading causes AOL to sign off, and if a download is set to take longer than an hour or two , at some point AOL will need to re-connect and fail the download.
Also, in the past week there were three instances in which Windows gave the "Virtual Memory is Low" message, one of which when the PC was idle- connected to the Web but no one was using it. I haven't gotten another one for about five days now, though.
I have a good amount of free space on the harddrive, and I have run Windows Cleanup and I just recently DeFragmented. Could these be virus symptoms?
