How to Remove Windows Computer Viruses Manually?
You are usually advised to run a virus scan to identify and get rid of such threats, although, these scanners are not always effective. Some viruses tend to form blockages and attack even the antivirus, making it blind. In such a situation, a user is commended to remove these viruses manually.
This editorial entails the systematic procedures to exterminate a virus and/or malware on your own. In order to do so, you should be knowledgeable enough to remember the name of virus your PC is encountering. These definitions and names are identified by your antivirus in the scan results. The antivirus is able to detect these threats, but lacks the ability to remove them. The exact virus terms can also be searched through the internet by keying symptoms. Once you are done with the name, accomplish the commands below.
Step 1: Operate in Safe Mode
Viruses tend to load themselves spontaneously as Windows boot. Keeping this in view, you need to boot into an environment that is unsupportive to such behavior. Boot in Safe Mode for a limited level of activity. For this purpose, restart your computer and continue pressing F8 until the Advanced Boot Menu appears. In this menu, choose Safe Mode with Command Promptto pass through.
Step 2: Locate the Path
In the safe mode, explore your folders targeting the name of virus, logged earlier. It could exist on your Desktop, Start menu, and Directories. Navigate to its actual location as it just has a shortcut on the Desktop and/or Start menu. To trace the actual location, right click the icon and go to its Properties. On the Shortcut tab, jot down the full path address stated in the text field next to Target.
Step 3: Remove the Infection
It is notified that a virus almost always has .exe file extension. Go to the exact folder, containing virus, identified in the previous step. Right click the virus icon and click Delete while holding the Shift key. Identify other doubtful icons in the same area; with the name containing random mix of letters and numbers; having .exe file extension; and modified in a most recent date. Delete all such files as well.
Doing this requires superfluous care. If you run these files mistakenly, the virus will become active even in the Safe Mode.
Step 4: Sniff the Traces through Directories and Registry
This step is to be performed if you are unable to find a shortcut icon of the virus on Desktop or Start menu, and you even do not know the name of virus. The most common folders for the presence of a virus are Local and Roaming at C:UsersUsernameAppdata. Another known location, in this respect, is C:ProgramData. Locate the viruses in these directories and Delete them straightaway.
Another way to exterminate the virus is by deleting the related registry keys. There are recognized registry paths towards certain keys that are vulnerable to the viruses. Press Windows key on your keyboard to view the Start menu. In the Search box, type ‘regedit’ and hit Enter to open the Registry Editor. In the left pane, navigate to the following listed keys. These viruses are identifiable on the right pane, as these are misspelled or named as a combination of random numbers, symbols, and letters. These registry keys along with the paths are listed as under. Press Windows key on your keyboard to view the Start menu. In the Search box, type ‘regedit’ and hit Enter to open the Registry Editor. In the left pane, navigate to the following listed keys.
Following are the routes, where you can find the traces of the identified virus. It is to be noted that 32-bit Windows has a single registry path, for 32-bit applications, as it does not run 64-bit applications. On the other hand, a 64-bit Windows entails dual paths, 32-bit and 64-bit registry entries, for 32-bit and 64-bit applications respectively. A 64-bit registry path in a 64-bit Windows is similar to that of 32-bit registry path in 32-bit Windows. A 32-bit registry path, in a 64-bit Windows has an additional key extension, named as WOW6432Node, as demonstrated below.
