Solved IE 9 wont open up.Why?

[Denv12]

Today I was online and everything was going okay.I downloaded a trial antivirus thats when I discovered IE9 wouldn't open up.I click on the icon in the taskbar and nothing happens.I got to the star menu and click on that and still nothing happens.I've gone into internet options and reset.That didnt do anything.It still doesnt open.

I have done full anti virus scans,ran superantispyware scan.I havent done a system restore.

I'm using windows 7 home premium.
Intel (R) Pentium (R) CPU G850 @ 2.90 GHz
46 bit operating system.
Bitdefender internet security
Superantispyware
Anvisoft cloud system booster

Can you uninstall that trial anti virus and see of that fixes the problem?

Hi.I took your advice straight away.I uninstalled it then restarted the pc.As it was restarting it did a start up repair then as I got back online IE9 worked.To play it safe I reinstalled kingsoft free anti virus and immunet free.I run one first then the other after.

I was using a trial of nortons about 4 weeks without any problems.Today I decided to trial another one.That anti virus software worked but I lost IE9.

Thanks for the advice.

Microsoft Security Essentials is a free alternative.
