Hello. After opening some files i downloaded from the net , i soon noticed that none of security softwares were running ( Avast , agv anti spy , sygate firewall). I tried running them , it says " not a valid win32 application". I cant reinstall them , and i can neither boot in safe mode. The only antivirus i have been able to run yet is Bullguard. It has already fixed watever it could find. I have also run n repaired errors with regclean and tuneup2007 registry cleaner. I dunno why , but whenever i run SuperAntispyware , my pc keeps rebooting. I cannot either run HijackThis. I have no Norton or Macfee softwares installed. Am trying to solve this problem since more than a week now , i need your guidance friends. Thanks for ur valuable time .

If you can boot to Windows, why not try a restore? Life's more painless for the brainless.

>>> i soon noticed that none of security softwares were running ( Avast , agv anti spy , sygate firewall). <<< If you are tring to run 2 AV's at the same time there will be lots of conflicts. What happens when you try booting in to safe mode? Does it hang? Does it just reboot immediately? More info would be nice Some HELP in posting on Cnet plus free progs and instructions Glad to Help!

Abandone hope of fixing it, i had a similar problem, believe it or not your in the early stages of what will destroy your comp. Reformat the computer a.s.a.p. before you have to delete the partitions off of it http://virusscan.jotti.org/ to scan your files if you dont have any scanners

yeah the same thing happened to me and i had to reformat the harddrive and put a fresh copy of xp on it.
