Recently purchased Norton 360 2013. Post install, ran Registry Cleanup. Suspect that this has corrupted system as font issues in MS-Word and MS-Outlook appeared immediately afterwards. For example, fonts on 'Do you want to save your document?' form in MS-Word corrupted. Also fonts on 'Send/Receive' dialog in MS Outlook 2007 corrupted. Noticed that MS Sans Serif and Tahoma fonts missing from font list in MS-Word. Copied and installed these fonts and problem resolved. Question is, is this a known bug and what else might this software have deleted?
MS Vista SP2, MS Office 2007 SP3 with MS Excel 2010 over the top.
