I installed microsoft security essentials 2.0 and I like it but every time I download a program mse cpu usage jumps to 100% and my computer freezes for about 1 minute. Then after that, at times pages will be a little slower to open at times and run smooth at times. For some reason mse doesn't want to play nice. I have run a virus scan and also ran malwarebytes and superantispyware and they all come up clean. Just wondering if anyone has any thoughts as to what might be the problem. I uninstalled mse and am using avira but would like to figure out mse if possible.

I just downloaded MSE 2.0 and am going to test it on my other computer. Will report back how it works :)

Sounds like MSE is scanning the download file. I use Eset and it does the same with some files so that may not be unusal.

Yes. MSE 2.0 is very slow when updating and slow when scanning. I am disappointed.
avast! is still the best anti-virus on system resources.

I uninstalled avira using revo uninstaller and then reinstalled mse and now programs download okay. The problem now is that every so often the computer freezes for about 30 seconds and then runs okay. It is mse causing the problem because when it freezes, MsMpEng.exe jumps to 100% in the task manager. Not sure if I should wait to see if anyone can help solve this problem or just dump it and go back to avira.

This sounds like an issue with MSE itself.

For issues with MSE you can submit a ticket via e-mail to Microsoft Security Essentials Support or check at the Microsoft Security Essentials Forums: Ask a question.
