Norton AntiVirus Basic - Slow computer performance
I hope someone can help, I just got Norton Antivirus Basic. Immediately after downloading to my PC (Windows 7) slowed down to a crawl. I have to wait after every click of the mouse for it to responded. I use Firefox and IE. If I open another tab the wait is longer, 3 tabs open, still longer, with 4 open it will freeze and I have to close the browser via Task Manager.
Browsers have the newest versions, I have all Windows Updated current, I clear temp and history often. I optimize, I ran Norton Autofix.
This is crazy, does anyone have any suggestions. Thanks, Karen
