Suddenly my PC will not load up any programs and asks for the location of the file needed to run the program. Windows starts normally but then comes up with a long list of start up prorams like AVG and Zonealarm that it cannot open. I cannot also gain access to the internet. The last program to run before this problem suddenly arose was the daily scan by Winaso Optimizer, which seemed to operate normally and repaired 8 errors automatically.
I have tried to go back to a resore point before this happened, but can't gain access to the restore and back up facility on the PC. My OS is Windows Vista Home Premium. Can any one help please?
Hi rdave13, I can get into safe mode, but the PC will not let me run system restore. It keeps coming up with a security warning and when I try to run system restore it tells me that it is from an unknown publisher and loops back to the security warning again.
I am running the scans now. Rather than a virus or other malware, I always have AVG, Zonealarm, SAS and Malwarebytes running, I wonder whether a windows file needed to run programs has been deleted or corrupted. I tried to run my Windows DVD to use the repair facility, but cannot get the PC to boot from the DVD. Do you know how I can do this if the scans fail to show up anything?
SAS ran a full scan and did not find anything. I cannot get Dr Cureit to run, even in safe mode. Tried to run system file checker in normal and safe mode and it would not bring up the command prompt. As with Dr Cureit I kept getting the dialogue box asking if I wished to run it and then warning about the publisher and looping back to the warning again.
The problem is that I cannot get the command prompt to appear the dialogue box comes up in place of the command prompt. I have started the PC in safe mode with the command prompt option, but do I delete the text about the C drive etc that is in the command prompt before typing in the sfc /scannow
I'm not sure how to do this in bios and am worried that I might do some permanent damage. Can you explain how to set the bios to boot from the CD please. I will then go to try this option if rdave13's method fails.
