Both browser are installed on a Dell Optiplex 320 machine. Internet Explorer has a habit of losing connection to the Internet and typing url in the address bar no longer does any good. Restarting the browser doesnt help either. What does help is restarting the computer which happens about 3-5 times a day. (Unacceptable in workplace ). Mozilla Firefox works a bit better, however Mozilla now has a habit of shutting down unexpectedly with no errors, pop up notifications or prompts of any sort. Also very incovnenient.
I have tried Malwarebytes Anti-Malware as well SUPERAntispyware. both came up empty in terms of adware,malware,etc.
I have recently upgraded the network driver to the latest version off the Dell's web site, however the person using the computer is unable to tell me whether these problems have occured before of after. (I'm an IT guy here at a small company). I also flashed the BIOS to latest on the same machine. Once again taken off DELL's web site.
My next step probably will be sfc /scannow, TrendMicro HiJackThis and attempting to reinstall both browsers mentioned.
However I would like to get a second opinion (and maybe a third and fourth) before I proceed any further
