Good day everybody.
Running ie11 on windows 7, about 2 weeks ago I could not manage addons or search engine, enable/disable are not accessable. I removed avg that made me crazy with avg isearch and installed microsoft security essential, also checked using spybot search and destroy and other spyware checker with no luck. so I don't believe I am recently infected.
I reset IE also with no luck.
Other web browsers I forced to use is google chrome and firefox working fine with addons.
