If I get an email with a link or hyperlink, as soon as I click on that link I get a dialogue box saying; "This operation has been cancelled due to restrictions in effect on this computer. Please contact your system administrator". (Me, in this case) Can't seem to find he cause, and nothing been altered or downloaded for some time. Checked IE/ Tools/ manage add-ons etc. Disabled and enabled them again, but can't find any problems with them. Anything else I should look for? Thanks.
