can't download anti virus on infected laptop

try booting into "safe mode with networking" by pressing F8 a few times when you first start the computer. Then see if you can download anti-malware from malwarebytes.org, update and run it first....then I recommend putting AVAST anti virus on, it's one of the better free ones. Then run a scan with it.

If you have McAfee or norton on the problem PC be sure to use the uninstallers from their websites to remove all registry entries or no AV or firewall will work properly Some HELP in posting on Computing.net plus free progs and instructions Cheers

First thing to do is, have a back up files, then format your PC, and last is install antivirus. If you have already installed anti virus in your PC, just connect to the internet and update your anti virus.

You can try a few things to download any anti-spyware or anti-virus program... 1. Use an Alternate Web Browser Application 2. Start Windows in Safe Mode (using F8 key at startup) 3. Turn off DNS Caching 4. Check for Hosts File Hijacking Sourced from: http://www.enigmasoftware.com/canno...

Re-formatting is a last resort. if you have a flashdrive or cd, use another computer to download a anti-virus that runs off of USB and do a scan that way. Panda also has a download that you load on a CD and boot from it to clean your system of viruses.

have you tried Avast?, it is one of the most complete applications for the control, elimination and protection against malicious code. ;)
