Thanks. I did attempt to run the suggested software (Malwarebytes), but it was quickly anesthetized by Antivirus.NET. Went to try to run in Safe Mode, but my HP has a weird boot manager and no simple "safe mode" switch. However...even though Vista Home Premium is not supposed to be able to be able to reset to a prior date, the H.P. recovery mode made it possible, so I took courage and pushed the reset date back to two days prior to infection. Low and behold, it seems to have worked brilliantly; although I'll have to redo my recent changes to networking connections - no biggie. Updated my windows security software and ran a full scan; nothing shows. Installed the Malwarebytes software, updated and ran a quick scan, no sign of antivirus.NET.
