I need help with a major virus/malware issue, I'm not sure what I have but it's bad. Last night AVAST warned me about an infection, I tried to delete the virus/malware but the PC froze. When I tried to restart, it would freeze on the blue welcome screen, I'm running XP. I went to safemode and from there I tried to run an AVAST virus check at restart, it ran but then the frozen blue screen issue came on again. In safemode I ran a virus check but it didn't find anything. From safemode I restarted the PC, this time it worked but a message from Microsoft about installing updates came on, I tried to run that, it ran for a while but then the machine froze. I tried to restart but again it froze on the blue screen. I went to safemode, restarted from there, again it worked, but this time I can't find some programs like Netscape or some folders like the system folder. I shut it off, restarted, but again it locked on the blue screen. On safemode I can find all the programs, except I can't access the system restore function. Any suggestions on what I should do?
