System running Windows 7 Home Premium... Service pack 1... 64-bit system. the System is a Dell, 4GB RAM, Intel i3 processor...
Due to a "virus" issue, I recently replaced the entire hard drive, and reloaded the OS, McAfee Security Suite, MS Office and a few other programs I use... I have yet to reload any of my backup data (photos mostly)...
I have McAfee Security Suite (through AT&T Uverse), and I have been running Full scans (manually initiated) 2-3 times per week... I think Microsoft Defender may still be running, but not sure.
Everything was fine until today... I noticed the system was VERY slow... I also noticed that when I tried to download a .pdf catalog from several companies (reputable), the files would download, and a popup said something about my security software did not allow the download ( I had downloaded other .PDFs recently -work stuff I sent to myself , etc. with no problems, and the popup did NOT mention "McAfee").
As I am writing this, I am having some issues with the text...
Ran a scan, and nothing (McAfee found nothing)... I rebooted, and ran a scan in safe mode, and NOTHING...
Opened Task manager, and in the "processes", I saw NUMEROUS processes that were running, but running and using more memory then I have EVER seen... I figure something is definitely wrong, but I don't know what...
Here's a list of the processes I noted, that seem to be the problem:
dpnsvr.exe*32"open file location"... I tried to delete, but I can't because
Most of these show using memory of 50,000K to 900,000+ K... I honestly NEVER saw any of these processes before ( aside from the svchost and dllhost) when I was having my previous issues, and I don't recall seeing any process using more than 130,000K (Internet Explorer, maybe), EVER... I also saw several of the same processes open. So I am pretty sure something is wrong...
Within Task manager, I have been trying to "end process tree", and they all close, but they usually pop back up quicker than I can end them... Right clicked on a process, and the pull down opened, clicked on the process, and tried to delete, but "access denied"... "you need permission from the Trusted Installer..."
So far ALL of these processes are located in the Windows\sysWOW64 folder...
