Thanks for your input FreewheelinFrank !
In fact you may perhaps call me a paranoid,because I have AVAST(Resident as well as periodical scan-at least once a week,automatic updates),SPYBOT-S&D(TEATIME,RESIDENT AND WEEKLY SCAN)INSTALLED IN THE SYSTEM TRAY(In fact these two are the only applications in start up.
But besides that almost daily use of CCLEANER,ROGUE REMOVER,SPYWARE BLASTER,ADAWARE are the additional .
And once a week kind of scans by additional safety productslike SPYSWEEPER.,REGSEEKER,ROOTKIT REVEALER ,SUPERANTISPYWARE.ETC
It was as a trial of occasional use of SPYERASER THAT I ran into a situation mentioned above,which is a learning exercise for newbie like me
I HOPE WITH THE GUIDANCE AND HELP EXTENDED BY THE EVANGELISTS HERE,I CAN LEARN HOW TO GET OUT OF TOUGH SITUATIONS WHICH I LAND INTO BECAUSE OF (AS MY NAME SUGGESTS) BEING QRIUS2NOALL
CHEERS
