Hvorfor får jeg hele tiden system alerts?

Jeg får hele tiden beskeder om at jeg skal rense min pc "system alert" - "your windows registry is corrupted" og så anbefales adskillige adresser som fixthereg.com, cleanthispc.com mfl. via tjenesten messenger. Hva' er mon meningen med det? jeg har læst andre steder at det er spyware. En anden bruger herinde har anbefalet hijackthis og så vise en kopi af logfiler - så dét gør jeg i håb om at nogen derude vil give mig et råd om, hvad jeg skal foretage mig...håber at høre fra Jer!
