Remove Virus from Your Computer

Got a virus on your system that doesn't show any sign of leaving? Well viruses are made not to leave the system.They just keep on bothering you and might even steal your private information.So what to do if your system has been attacked by a virus?
This guide tells you some simple yet essential steps to make your PC virus free

1. Disable system restore, most viruses go into system restore and to get them out it has to be disabled.
Windows XP:

Steps to turn off System Restore
1. Click Start, right-click My Computer, and then click Properties.
2. In the System Properties dialog box, click the System Restore tab.
3. Click to select the Turn off System Restore check box. Or, click to select the Turn off System Restore on all drives check box.
4. Click OK.
5. When you receive the following message, click Yes to confirm that you want to turn off System Restore:
You have chosen to turn off System Restore. If you continue, all existing restore points will be deleted, and you will not be able to track or undo changes to your computer.

Steps to turn on System Restore
1. Click Start, right-click My Computer, and then click Properties.
2. In the System Properties dialog box, click the System Restore tab.
3. Click to clear the Turn off System Restore check box. Or, click the Turn off System Restore on all drives check box.
4. Click OK.

Windows Vista:
1) Type system into the start menu search box, and pick the 4th item down, just labeled "System". (You could also right-click the computer icon and choose properties)
2)Now click the System protection link
3)Once you uncheck the drive, click the "Turn System Restore Off" button
4)To enable repeat the steps and then check the drive box that you had unchecked before.

2.Backup only important stuff, if you start backing up everything infected files may transfer. However, this might not be needed unless you got really important stuff.
If the virus infected your entire OS and you cant boot into Windows by normal mode or Safemode use Hirens Boot Disk 9.5. It comes with small version of Windows 98 that runs from RAM it can be used to back up important files.

3. You should get Hirens Bootdisk 9.5, scan with the 2 antivirus programs and antispyware programs before Windows starts!! Use this disk to test other hardware problems such as test bad RAM, bad hard drives, ect

Download Hirens bootcd 9.4 + keyboard patch

If you can start Windows and can get to desktop install and run this freeware , SuperAntiSpyware, Spybot Search and Destroy, Ad Aware 2008, McAfee Stinger, Spyware Terminator, and Malwarebytes Antispyware. Also some good other freeware programs you should get; CCleaner, Glary Utilities and Advance WindowsCare Personal. Run one program at a time, or if your computer is fast run two at same time.

All freeware spyware removers plus CCleaner, Glary Utilities, Advance WindowsCare Personal only 67MB's

5.Start Windows in safemode and install Hijackthis save the log and then go to

That site will tell you what to delete using Hijackthis. When your going to delete something that gets picked up as nasty or virus. Make sure you go into google and look up that .exe files, it could be graphics driver or printer driver. Hijackthis picks up my Lexmark driver as a possible bad file but its not. So be sure you know what your deleting cuz Hijackthis deletes them and it wont bring them back if you make errors. If your unsure about your log save it and go to Help section and post it.

6. Get the latest Geek Squad CD; run all of its antivirus programs. It should remove something. BTW you should disconnect from the internet before using this CD and it will be flagged by some antiviruses cuz it trys to phone home.

Download links
part 1, you have to extract it out of this rar, and put it next to the other rars

7. Once you think you have cleaned your PC, restart normally if things seem fine then check your computer using this free online virus scanners!! Run one by one till you know your clean. If one of them comes with virus result, write down its directory and name of it. Then post question in the Comments of this post.We at VishTecho will try to find a solution for your problem.Or download the antivirus that detects it and uninstall your current one and use the one that picks up the virus.

8. Last step is to Install CCleaner and use it to delete temporary files.
Its very good program, i use it to remove around 1 GB every week. Imagine if you never run it? You probably can gain more space!!!
Another thing you could do is create a shadow copy of your hard drive in case anything ever goes bad you can just reformat hard drive and install this shadow copy. Use Hirens BootDisk it has Acronis True Image for backing up your whole PC.
I suggest you give Kaspersky or McAfee antivirus a try. They are the best To remove your current antivirus and try other ones use Your Uninstaller 2008. I recommend you always use LEGAL antiviruses so you can update their definitions everyday.

If you cant afford an antivirus get a free one! This are free antiviruses (you can only use one at a time)
