Looking for some software (pref free) to get rid of spyware/trojan off the wifes laptop
What to use ?

Cheers

For antivirus/spyware try Avast or AVG (both free for home use).

for spyware and trojans i tend to use Spybot

If you've deffo got spyware and Trojans on the laptop if you use it for on-line banking/shopping the best thing to do is reformat it IMO!

spybot search and destroy is good, if a little clunky to use. install it, update it, immunize ( sic ), scan, follow the recommendations, then go into the options and select 'scan at next system start', then restart and scan the machine again. it'll take a little while but should get everything out.
it is not an anti virus program though. for that use avg or avast as above.

Ccleaner (formerly crap cleaner) is about the best i've found:

It's free, or you can make a paypal donation.
