The Clean Up Procedure to Remove Malware and Viruses with External Scan
In continuation to previous articles on removal of malware (malicious software) from Windows machine that is infected, everyone facing the problem will tend to argue that it’s better to scan infected machine from outside to overcome the effect of defenses within the malware. The preferred option is to use anti-malware programs on boot CD for Window (UBCD4WIN); the CD can use two methods to clean malware from infected machine – one the network access and second the software with Ultimate Boot CD to be used with windows.
The removing of malware should be carried out on a disk image backup. The image backup programs will copy an image of the complete computer image; these programs can be run from bootable CD or USB flash drive. Copy the image of the entire computer on another computer machine in the network or to an external hard disk.
AntiVir antivirus program from Avira included in Boot drive can be used to start clean up process. In Avira the virus definitions updating is very simple when the infected computer is online. Another program SUPERAntispyware when run after AntiVir has removed malicious software.was able to find and remove malicious software. If infected computer is kept online then latest definitions are downloaded automatically but if computer is offline then spyware definition date is harder to get.
Another anti-malware software in the UBCD4WIN CD is McAfee’s Stinger. It is a stand alone utility which is able to remove some viruses from infected machine even after AntiVir and SUPERAntiSpyware has been used. SpyBot Search and Destroy snd Virus Cleaner are other programs which have capacity to remove limited viruses only. For online scans, IE version ^ is better than Internet Explorer.
Local Area Network scanning: To scan infected machine over a network any anti-malware software installed normally or online can be used. Eset that makes NOD32 provides a free online scanner. Online Scanner from BitDender detects and subsequently removes viruses and spyware. If malware cannot be removed then the default action is to delete affected files.
Removing Malware Externally: After external scan done on the infected machine first time the machine was booted it was found that some programs were unable to start correctly. After giving a thought it turns out to be those programs that were unable to boot automatically in fact had been infected by malware. Actually while scanning from external the anti-malware program treated registry files in the program as a bunch of simple file stacks and hence the malware found was deleted.
Next step to be done was doing scanning the newly cleaned out operating system from inside with anti-malware software. This will clean up the registries in the system. Thus host of unnecessary files will be removed. Disable System Restore to remove all restore points. Remove all temp files browser cache is to be cleaned up foe all browsers and in the end empty Recycle Bin.
