1. I was not able to open any folder in same window?
every time system opened new window while clicking any folder and facing unwanted process so memory consumption is high even system has no activity
(Virus name: autorun.inf)
Solution:
Normally when a virus infects a windows system which causes a drive opening problem, it automatically creates a file named autorun.inf in the root directory of each drive.
This autorun.inf file is a read only ,hidden and a system file and the folder option is also disabled by the virus. This is deliberately done by the virus in order to protect itself. autorun.inf initiates all the activities that the virus performs when you try to open any drive. So You have to just delete this file and restart your system to correct this problem.
Follow the set of commands below to show and delete the autorun.inf
1. Open Start>>Run and type cmd and press enter. This will open a command prompt window. On this command prompt window type the following steps.
2. type cd\
3. type attrib -r -h -s autorun.inf
4. type del autorun.inf
5. Now type d: and press enter for d: drive partition. Now repeat steps 3 and 4. Similarly repeat step 5 for all your hard disk partition.
6. Restart your system and your trouble will be fixed.
2. My Task Manger was disable and not able to kill or end task any process
Why is task manager grayed out? Or Why is Task Manager Disabled?
There is a registry key that will disable Task Manager, although it’s not always clear how or why it was set to disable. In many cases the problem is related to spyware, so you should also scan your computer.
Solution:
Manual Registry Hack
Open up regedit.exe through the start menu search or run box, and then navigate down to the following key:
HKEY_CURRENT_USER\Software\Microsoft\Windows\
CurrentVersion\Policies\System
On the right-hand side is a 32-bit REG_DWORD value named DisableTaskMgr with one of two values:
• 1 - Disable task manager
• 0 - Enable task manager
Just double-click and change the value, or even delete the key. The change should take place immediately.
3. Antivirus: Windows: Troubleshooting
LiveUpdate could not retrieve the catalog file of available Symantec product updates,
please check that your connection to the Internet is functioning properly.
Problem: When trying to run a LiveUpdate, user gets the above message.
Solution:
Many recent viruses place an entry in a computer’s hosts file that prevents it from connecting to the LiveUpdate server. To fix this,
1. Open up Notepad from Start > Programs > Accessories.
2. In Notepad, go to File > Open, select “All files” from the drop menu, navigate to c:\windows\system32\drivers\etc and open up hosts (in Win2K, look in c:\winnt\system32\drivers\etc).
3. Remove any entry other than 127.0.0.1 localhost (scroll down to make sure there isn’t anything below).
4. Save, close, reboot, and you should be able to LiveUpdate.
