you can use Mwav from E-scan which is based on the Kaspersky engine, you need to re-download it after a month, very thorough scanner!
Here's my spiel on how to use it and set it up!
Note: this is a stand alone, it doesn't install to start/programmes.
Download Mwav, double click on it and it will extract to C:\kaspersky. Click on the kaspersky folder and click on Kavupd, a black dos window will open and it will update the programme for you, be patient it will take 5-10 minutes to download the new definitions. Once it's updated, click on mwavscan to launch the programme.
Use the defaults of:
Memory
startup folders
Registry
system folders
services
Choose drive , all drives and, click scan all files
and then click scan/clean.
Note: this is a very thorough scanner, it might take anything up to an houror more, depending on how many drives you have and how badly infected your pc is.
