    The Virus i Encountered Yesterday which i Removed
    I Figured it out that my Firewall was Disabled and i turn on my Firewall but when i Open a File My Firewall Turns Off and my Task Manager, Regedit Disables too.
    I Used Spybot to remove Errors and it returned Task manager and Registry and Firewall Notify. but when i Restart and or Open Internet Explorer or a File it Disables Them.

    1st Problem:
    Well another problem when i Fix Task Manager and Registry Edit and Firewall.
    When opening Files that are Recently Healed by my Anti Virus it removes my Task Manager and Registry Edit and Turns Off My Firewall.

    2nd Problem:
    Very Slow Windows XP Loading Screen then After Showing Welcome Screen it's very Slow too at Startup. and So Slow at Opening Files like Internet Explorer takes 30 Seconds to open but when the Computer get used to it it's Fast.
    and I Close and Reopen Internet Explorer it Takes 30 Seconds to Open and when the Page Showed up it's Fast. Free at last. My Problem is when opening at Programs its Very Slow.

    Should i Post Hijack This Log
  5. And the Internet Explorer Options too are Affected I cannot use it maybe It's Controlling by a Newer or 2011 Spyware.
  6. I've Solve The Problem The Problem was there was Damaged Boot Sectors on my hard Disk because i didn't Boot Check C: and D: is the only one i Boot Check. because my Hard Disk is Partitioned.
  7. so the there were damaged boot sectors?
