I installed 7 and everything seemed fine. Then I installed Avira AntiVir (installation went fine). The first time I restarted the PC after its installation, however, windows wouldn't start, and couldn't be repaired without the Windows 7 Installation DVD. I finally restored to a point before Avira installation, but after the "succesfull" restore, avira was still there...
Do you think the issue was caused by Avira? (I manuallly uninstalled it now). Anyone with similar issues?
