Years on on an XP computer, I installed McAfee anti-virus. I later tried their firewall.
As updates became bloatware and slowed the computer ridiculously, I ‘uninstalled’ both.
Every few months, I would get a pop-up from McAfee asking me to re-try their software. I thought I had scrubbed everything McAfee from the computer. I had even gone through the registry file. Still, I would get the pop-ups, until I had other problems and had to reformat and reinstall XP.
Since then, I would never let anything McAfee on my computer(s), even though my cable ISP offers McAfee security software free to users.
Now, on my Win7 laptop and desktop, I stay with Windows Security Essentials and Windows 7 firewall. They play nice with other software and do not seem to bog down my computers.
Me too. I use Windows Security Essentials and Malwarebytes, very compatable and no interference (slow down) with other programs even when editing HD video. Norton sucks. A computer programmer once told me that Norton gets into everything and your computer slows way down.
