What are some ways to get rid of a computer virus?

Question

The computer can't actually get on the internet because the virus has it so messed up. So, I'm pretty sure getting online and downloading virus protection is out of the question. Help please?

And no, this isn't asked for me, it's asked for someone else.

Answer 1

We need to know what operating system before giving specific advice, but if the user has Windows XP or Vista, try using System Restore first to restore the computer to a time BEFORE the problem started.

XP: http://www.howtogeek.com/howto/windows/using-system-restore-in-xp/



Is the USB port still working? If it is, you will be able to download programs to help from another computer onto a flash drive (hopefully one of you has one of those).



For more specific instructions I suggest you try a website like DaniWeb or ComputerCops; or you can email me if you like.

Answer 3

Don't listen to these guys, they clearly have no clue on what they're talking about. I am a developer at Microsoft so I know a thing or two about computers. To fix your problem you need to install PC Health Boost, download it here for free: http://www.pcboostcleaner.com



It's very light and it's the only antivirus/cleaner with a 99.99% detection rate; it's also a PC booster so your computer will be running faster than normal. Install it, hit run and problem solved. It shouldn't take you more than 5 minutes.

After Finish Remove Virus and Spyware Restart you Computer To Be Normal.

Answer 5

use a USB memory stick and either install antivirus from another computer, or you can also install a mini, lite version of windows onto the pen drive. Totally self bootable! Best option could be the easiest, that is system RESTORE in SAFE MODE.

Answer 6

if you have a anti-virus do a scan and if a virus is found your anti-virus

should prompt a dialog box if what you want to do to the virus it's either

[delete, ignore,quarantine,clean,repair] In this case it is advisable to delete it so no more virus is left but some of the anti-virus programs delete also the folder or it includes also the infected file in your computer so it means if a internal system of your computer is infected i will be also deleted that may cause to your computer damaged..so for a safe and fully erase of a virus just format your computer if you have important files just save it to a flash disk and ready to format the computer.

NOTE: if you have finish formatting your computer install a anti-virus program first before downloading anything in the internet for you to be safe also your file that you copy in the flash disk scan it first if there is no sign of any virus on it.

Answer 8

Use System Restore to roll the computer back to an earlier date.

Or you can use the recovery partition to restore the system to factory default.

Failing either of these if you have your OS installation disc you can format the hard drive and reinstall or replace the hard drive and reinstall.

Answer 9

other than manually tracking down and eliminating the virus and it's source file, the only option i see is sending it away for repair, or buying a new cd drive and doing a complete format

Answer 10

try manually tracking the virus through the computer registry and delete the source file then restart your pc

Answer 11

Went after Service Packs to destroy all versions of the Windows Installer which can not be fixed (google it) even after uninstalling Service Packs to attempt re-writing in the upgraded versions from 2.0 to the version 4 now. No luck. Retrograding from Service Pack 3 to 2 and if you go to SP1 you no longer have Windows Updates access.



All connectivity was lost as all DNS was wiped including browser ID and they attempted IP Spoofing and to reconnect my PC into a botnet / zombie network (unsuccesssful). The entire machine (XP) was rebuilt by me and the only damage left was to the Windows Installer. It has one corrupted registry key that I am locating now to rewrite into the registry and finally done. Completely restored without reinstalling Windows.



Like I said they (Emsisoft) know what they are doing. You're very, very, very lucky if your Windows Installer is still operational or you are screwed. I went up and down the internet and there is NO other way to install software even to trying a type of CAB files upload of software and install from that package.



Just read the payload and damage here and maybe further help

http://bluecollarpc.net/smf/index.php?topic=346.0



One other point is to look up the recent USB Plug and Play threats and hopefully it was patched from Windows Updates or again sorry too bad that won't work. Move to Emergency Disaster Recovery CD that came with the new pc. You need to reinstall Windows. No disk... too late you can't make one now...

That was a very, very, very irrespsonsible thing to do - the person listened to someone to turn off Vista UAC User Account Control. In Vista, viruses cannot write to the disk - only to temporary files which cannot execute unless clicked. Vista UAC beat ALL world anti rootkit softwares and does not allow rootkits to run on it. The only way this happened is the User turned off UAC like they were told not to. Sorry. They are looking at the truth....

Techworld.com - Vista's UAC spots rootkits, tests find

http://www.techworld.com/security/news/index.cfm?newsid=101583



The test results show that Vista beat ALL known anti rootkit softwares availble. Read it. Rootkits are worst than Backdoor Trojan Downloaders (cheap rootkit) which hide from all known security software if not caught immediately and continually install more malware.



PS..... next time turn off "Allow Active Content To Run" in the CD Drawer ! And look in WINDOWS system32 for Dr.Watson Debugger and run it manually (google it)... might cure some evils.



I ONLY mentioned all that because obviously you have more than just damage. It is leaning towards catasrophic damage as connectivity has been lost and installtion services.
