I've been trying to repair the computer at work, so any requests for system information and such will have to wait until I get back there, which is why I want to post this now. Basically, it's running a 32bit Windows 7. We were having a problem with browser redirects in IE and Firefox, so I ended up uninstalling and then reinstalling Firefox. I then deleted all the keys for any Internet Explorer addons using RegEdit. This seemed to fix the problem with redirects. However, I notice that I some programs won't run. Particularly, Windows Security Essentials. When I click on it, it opens for a micro-second (trust me, I timed it - ok, not really) and then closes. I feel as if there's some code somewhere instantly shutting it down. I'm wondering if something like Process Monitor would help if I were to start MSE and see what processes start to cause it to close immediately after. Would this be the proper way of going about troubleshooting this? Prior to all of this, I had run Housecall, MalwareBytes, and CCleaner. CCleaner found a bunch of issues, but all my virus scans came up clean. Any suggestions would be great as I will be able to put them to use as soon as I get back in to work. I'll also be able to find out if the browser redirect issue has been resolved or has come back since my absence. Thanks!
