Well, I am done with anit virus but now I am hooked up with Anti Spyware. I came to know that SPYWARE S&D is the best, but still it could not solve my problem. Recently, my system was infected by a file called MAYDAY.dll and now if I open my Local Disk C it has some unwanted or unknown files in hidden properties, as Config.Msi, AUTOEXEC.BAT, NTDETECT.COM, sqmnoopt02.sqm, and many more as such. When ever I go to any drive, I can see a file named a RECYCLED, but when I tried to delete it, It comes back whenn I restart my system. Is those files unwanted or something riskfull? What should I do to come across these files. Please do let this NewBee know about the system.
