Firefox won't open, Explorer won't connect

Hello,
I'm running Windows 7 Professional and I've just started having a doozy of a problem. I'd really appreciate some help.

As it stands, when I try to open Firefox it asks for permission to allow the program to make changes, then if approved, the programs just closes. Viewing it on task manager it just pops up and vanishes.

Trying to connect via Explorer. Explorer will OPEN, but it cannot connect to anything.

Outlook seems able to SEND messages, but cannot recieve messages.

Any ideas?

I can browse with Explorer, but Firefox still will not open.

Did you uncheck your proxy settings for the browser?
I am not certain how to do this.

Disabled all antiviruses and tried?
No change.

No change

When did this issue start?
Avast found a virus (I foolishly didn't make note of what the problem was). After clearing the virus a boot-time scan was recommended. The computer wouldn't boot (it wouldn't even load the BIOS). Most likely the virus had damaged the MBR.

After disconnecting the HD, I was able to access the BIOS and loaded a Windows Recovery disc. This corrected the issue and the computer was able to boot. However, it then developed this problem.

Network drivers working fine?
I'm not certain. I BELIEVE so. I can access other machines on the network just fine....

Kaspersky finds no threats

Can your inbuilt html browser reach google.com?
Yes, it can.

Run as administrator was not checked. Ownership was Admin rather than myself. I changed that, no difference with the issue.


Did you try reinstalling your firefox?
Firefox now updates/re-installed and working. Add-on "Microsoft Default Manager" disabled

If you can browse using your html browser then you can try to reinstall your browsers.

Avast anti-virus. I'm open to suggestions if there is something better though.
