First Aid if Virus Infected

Monday, June 22, 2009 | 11:18 pm
What to do if a virus infected computer? Do not rush out Pasopati science, aka "format" and "reinstall Windows"! In some cases the virus, such as Conficker, this does not solve the problem. Your computer will become infected again once connected to the network,
So what? Try to always handle yourself with a two-step that PCplus show. You lose the same period a virus?
Use System Restore This is the stance of the easiest but powerful if you want the computer to run both the pre-infected with the virus. System Restore is one of the leading features in Windows XP and Vista which by default is enabled when the OS was first installed.

With System Restore you can create a restore point (which also automatically made periodically by Windows). It's like a time machine. That is, when the system is 'acting' is not fair, because a virus or any programs or drivers installed, we can restore the configuration of Windows, such as when a computer healthy.

For example, there is a new application-OS install and cause problems / frequent crashes. Instead of a headache and spend time analyzing fault location program, just call Restore point when the program has not yet been installed. And Voila, all registry settings and other Windows configuration again as usual.

Restore Point can be applied if you know roughly when the virus infects a computer, or in case you do not run a virus file. There's only condition, ie, System Restore is not disabled, by a user or a virus (some viruses such as Conficker disable System Restore when the computer attack the victim).

Unfortunately, System Restore often backfire. Jka already entered the Restore point, the virus that infects a computer it is protected by System Restore. As a result, even though it was cleaned several times with the antivirus, the virus occasionally stuck firmly in the files restore point. The virus will 'rise' again from the restore point. This is very annoying.

Therefore, each time step is cleaning the virus, the first step is to disable System Restore. This is so that the virus was not protected by System Restore. Here are the steps to restore its original state (Restore Point): 1. Click [Start] [All Programs] [Accessoris] [System Tools] [System Restore].
2. Three choices will appear in the System Restore wizard screen, namely: a. Restore my computer to an Earlier time. Use this to restore the system at any given time. b. Create a restore point. Use to create a restore point at this time. c. Undo my restoration. Use to cancel the restore points are made. Here PCplus select [Restore my computer to an Earlier time] [Next].
3. Next, you will be faced with a calendar. Choose a time when the computer is still stable or not infected with a virus, then click [Next].
4. The next wizard appears on the confirmation screen. Select [Next].

5. System restore will work, then restart the computer. You need to wait a bit longer, about 15 minutes (depending on your hardware), in order to restore Windows Restore Point.
Unfortunately, in some cases, the virus tries to turn off System Restore, so this feature is not useful. So use the System Restore feature only if the virus has not been turned off this feature.
Manual Cleaning If System Restore fails to restore the computer system, there are still other ways. This last stance is "Cleaning Manual."
Most importantly, DO NOT PANIC! The next step, data Save your work immediately and close all other programs running. Make sure the data has been stored at the correct location or right and you know their location.
After that, do the backup data to another storage media (USB flash disks, CDs, etc.), which is separate from the computer's hard disk. This is to prevent unwanted things on your data. If possible, it helps remove the infected hard disk and copy your important data onto the hard disk / other media.
After all the above you do, run the following steps:
1. Install an antivirus program and do antivirus UPDATE. If your computer has antivirus software installed, just do antivirus updates in order to prevent possible infection of new viruses. If necessary, a free tool unduhlah in Norman Malware Cleaner

To disconnect a network or Internet connection, this step: a. Click [Start] [Control Panel] [Network and Internet Connections] [Network Connection]. b. In Network Connection, select the Internet connection / network that exists, then right click and click [Disable].

3. Disable "System Restore" to facilitate the cleaning of a virus that is protected by a Restore Point and prevent the virus re-infect the computer. How:
a. Right click on My Computer, click [Properties]. b. Then in the [System Properties] [System Restore]. c. On the tab [System Restore], check the option [Turn off System Restore on all drives]. d. Click [Apply] [OK].

4. Do SCAN virus. Allow a full antivirus scan on your computer, including USB flash disks (if any). After the scan is complete, restart the computer if necessary. Alternatively, do the scanning by using the Removal tool.

5. CLEAN temporary files from the possibility of entry of the virus. Here's how: a. Click [Start] [All Programs] [Accessoris] [System Tools] [Disk Cleanup]. b. In [Disk Cleanup], select the drive that will be cleaned (by default is C:). c. Let [Disk Cleanup] scanning first. d. Select the temporary files that will be cleaned, then [OK]. e.
