I love Opera, and it's been working perfectly. However yesterday I installed some new anti-virus/malware protection software, and now it is unable to load. I can open it, but the main page will not load. Eventually it simply informs me that it is taking to long to load and I should take one of their suggested actions (I've done them all to no avail.)

It is not my internet connection, because Internet Explorer still can connect. The new software is iolo System Mechanic Pro. Does this problem sound familiar to anyone? Should I uninstall and reinstall Opera? Does anyone know what I should do?
