Hi. Apparently computer or operations has a problem when Windows startups left corner AVG antivirus icon shows massage as 'Your computer might be at risk!' Prehistory looks as a Microsoft Office 2003 had been installed but was running with a mistake as mail client had closed showing "Microsoft Visual C++ Runtime Library Error" regularly. I removed this programm from computer completely and got above mentioned antivirus warning, checking alert can to see description of problem as unenabled Microsoft Automatic Update but it is not correspond to reality because Update is switched in. Is it a virus or Windows discrepancy I don't know and please tip what should I to do?
