New member here and it seems like I should first post in this forum and see where things go based on advice.
System related info:
Windows 7 home premium 64 sp1 (regularly updated)
Microsoft Security Essentials (regularly updated)
Ccleaner (updated somewhat regularly)
Malwarebytes anti-malware (installed recently and updated regularly)
Short version: How do I investigate whether or not my system is still infected?
Long version (rough timeline)::
MS security essentials finds infection and it is quarantined and removed.
System seems fine
IE10 begins launching on its own and homepage it auto-launches to is Microsoft.com (not my normal homepage and not my normal browser)
Days/weeks later - MS security essentials finds infection and it is quarantined and removed.
System seems ok.
After repeat infection notification, download Malwarebytes anti-malware and run. Malwarebytes finds a few items. Items are quarantined and removed.
System seems ok.
Days/weeks later – both MS security essentials and and Malwarebytes find infections (again quarantined and removed). Also, computer now starting to have blue screen of death shutdown/restarts (It might be coincidence, but it seems that BSD’s occur when both Malwarebytes is scanning and system is online. System uptime much longer/indefinite when offline.)
As of today:
MS security essentials and Malwarebytes are showing no infections, but I’m skeptical that the infection(s) have been completely removed. IE auto launch into Microsoft.com hasn’t occurred recently. Although, BSD/restart still occurring (again may be coincidence, but seems to occur when online – and possibly when both online and when Malwarebytes scan is running).
Examples of items found by Malwarebytes:

Thank you for your time.
