i recently installed bitdefender on my PC but a power interruption occured while it was on the process of installing. when power return i tried to remove first the unfinished installation and i deleted all files related to it. but when i look at my security settings it says that "bitdefender is not on". how can this be when i deleted all its files but its still installed? and my internet explorer 7 can't be open again. i only use mozilla now. my other programs won't work anymore and theres always a pop message saying "the procedure entry point GetProcessImageFileNameW could not be located in the dynamic link library PSAPI.DLL." its really bothering me now. i can't use some of my programs. this pop message always comes out when i open my yahoo messenger. i installed bitdefender again and i succesfully finished it and i tried removing it and i thought i did but it didn't. i search for it in all files and theres no file of bitdefender anymore but my windows security says it bitdefender is still there. plz help me. i don't want to reformat my PC. is there any other way to remove this bug? i tried sytem restore but its appering unsuccesful. plz help me.
