Both Firefox & Internet Explorer freeze after only a few seconds. It started with Firefox & then started with Internet Explorer after using it a few times. They started by not being able to close all the screens except through Task Manager. It seemed to clear up when I did a System Restore or used older versions of Flash & Java, but after a few days they became unusable. I uninstalled Firefox & installed the latest versions of both browsers but got the same results. I scanned for viruses & Malware. I found a glitch in the hard drive & replaced it by imaging. I downloaded Chrome & it froze also but I found that Opera works ok. The only change to my system was installing a D-Link router which sometimes redirected to the router login page when I was trying to browse. I also installed ScreenConnect but had it disabled while testing. Any suggestions?
