I deleted my temporary internet files folder plus cookies yesterday, ever since then it has been doing this. Everything is like that on my desktop including my AVG internet security. Will not scan.1 person got this answerI do too

This could be caused by severe infection by malware that AVG didn't get and/or it could be a hardware issue with the hard drive being in PIO Mode. Back up your data first . The most efficient way to do this will be to pull the drive, put it in a USB external drive enclosure, attach the drive to a working computer and copy off the data that way. 1. PIO Mode explanation and fix from MVP Hans-Georg Michna - http://winhlp.com/?q=node/10 2. If the hard drive is still in PIO Mode after applying Hans-Georg's fix, the drive may be failing. Test the hard drive with a diagnostic utility downloaded from the drive mftr.'s website or use Seagate's SeaTools For DOS. You will create a bootable CD with the file you download. You will need third-party burning software to do this such as Roxio, Nero, or the free ImgBurn. Burn as an image, not as data. http://www.imgburn.com http://www.seagate.com/www/en-us/support/downloads/seatools/seatooldreg http://seagate.custkb.com/seagate/crm/selfservice/search.jsp?DocId=201271 (how-to) Boot with the CD you made and do a thorough test of the drive. If it fails any physical tests, replace it. 3. If the drive tests good, then severe malware infection could be the cause.
