I have researched lots of stuff on-line already but not seeing an answer.
I have a windows vista 64 machine with I7 processor and 6gb of ram. Norton, no viruses I know of. Normally machine (lightly used) runs with 49 processes, and 31% of ram <1% of cpu unless I am doing something.
For last few days it has been running 13% of ram, and 47% of ram with 1.2mb being svchost.exe. Normally, this is a background update, but I have literally left computer on for 36 hours straight, turning off a couple times to see if it would clear, but at least 18 hours straight. When I restart, it starts out low. I see trusted install come on for a few minutes at about 22,000, then memory starts climbing, and fan comes up and stays on. I might not notice this except for fan.
If it was a legit install, I would think it would eventually stop which usually results in a flag on shut down that says "shuts down computer and installs updates" but it just doesn't do that.
Norton is up to date and has run full scans while this is all going on. Is it simply a huge update? It was last updated in mid July. When I simply click on "check for updates" from control panel the dialogue box closes but never see anything. If I click it again, it says "update is already running". If I shut down, and restart, I can go through all of the above including this last item. I can click check for updates once, and it seems to initiate something that doesn't show. If I click it again, it says "already running". I was hoping I could force a high CPU full memory update. Heck, a whole install wouldn't take this long, which is what I might do. I am just not sure if it should be win7, win10 or what. I use my PC and large high resolution monitor for photo editing. That's about it. I surf with a laptop.
