It started a little while back, I wa susing my computer as usual, browsing the web, and instant messaging. Then, in the bottom right hand corner of my screen, bitdefender, my primary antivirus,had a little pop-up warning, saying it had found a virus on the computer. I cleared the firefox browser to make sure it was from my computer, and i clicked delete, so as to delete the virus. more little pop-ups like that came up again, I'd say about 4 in total, and i did the reccomended actions. Then a little while later, my computer started acting up, freezing. I couldnt run more than one application at once, or else i would have to wait 5 minutes for the computer to come around. I was a little worried, because this is a new computer. I restarted, and it restarted fine. I tried to do a system restore to fix said issue, but it failed. I restarted and booted into safe mode and ran a Malware bytes antimalware scan, but restarted again, and the scan never finished.since then, Ive been able to get into windows only once or twice. i rebot, and everytime 2 options come up, one is to use startup repair, and the other to boot normally. somewhere along the line, i ran a chkdsk, and came up with loads of errors. I ran start up repair many times, and it always was unable to fix disk errors. It asked if i wished to restore system to a time when it was working. I clicked restore, but it failed. I lost my windows 7 cd, but my aunt has one, and i might be able to use it. My opertating system is windows 7 ultimate 64 bit. I have 8 gb or ram. proccesor is Amd athlon x2 dual core. iI have a bootable usb of windows 7 ultimate. I dont have any back ups of my stuff, because windows back up disk creator confused me to hell. so no back ups. what ever is on that harddrive is the only copy i have, so i cant do a fresh install. any ideas? it would be highly appreciated, and followed by praise worthy of god. thnx. Right now, im using an old computer that i thought was dead running windows 7 ultimate 32 bit with 512mb. i got the iso to make the usb from a copy of the iso i had on my windows 7 dvd. i downloaded pendrivelinux, and made a bootable usb. Thnx.
