What does it mean that you tried McAfee but were unsuccessful? Do you
mean that you were running without an av installed, thought you had a
virus, and then tried to install McAfee? If this is the case, here is a
way to deal with that:
It sounds like you have picked up a virus that immediately breaks any av
installed. This could happen if you had an older antivirus version,
weren't updating its definitions or didn't renew your subscription. The
usual way to deal with this is to:
1) Take the infected machine off the Internet and any lan immediately.
2) From a different, clean machine download Stinger
(http://vil.nai.com/vil/stinger/) and run it in Safe Mode. Stinger is a
limited virus checker, but its advantage is that it is standalone and
doesn't need to be installed.
3) Hope that Stinger cleans up the machine enough to be able to
reinstall your av or install a new, current one. Update its definitions
and do a full scan.
4) Continue the cleaning process by removing any spyware with Spybot
Search & Destroy (http://www.safer-networking.org) and Ad-aware
(http://www.lavasoftusa.com). These programs are free, so run them both
since they complement each other. You may also want to run CWShredder
and HijackThis from http://aumha.org/freeware.htm. Although CWShredder
is no longer being updated, it will still clean older variants of the
CoolWebSearch malware. Be sure to update these programs before running
them. Always read the instructions before running a spyware removal
tool. It is best to run antivirus and spyware removal tools in Safe
Mode.
5) After you've installed your full-featured av, updated its definitions
and run a full system scan.
6) Make sure you are running a firewall.
7) Go to Windows Update and apply all security patches for your
operating system. Do not install drivers from Windows Update.
