What anti-malware product to use in conjunction with Avast?

[Harlequin]

What is a good free anti-malware product to use in conjunction with Avast on a slow WinXP machine?

I want something which scans for ad-ware, ransom-ware and suchlike which are not really viruses.

Would Malwarebytes be a good choice?

Malwarebytes is certainly not light on system resources.
For my money, you already get everything from Avast.

I thought Avast offers only anti-virus protection.  Do the file and web shields in my Avast 10.4 also detect malware (such as adware, ransom ware, etc) ?

Dont get so hanged up in the name these programs have as they are years old and things have changed a lot

All virus are malware, but all malware are not virus   

Malware = Malicious program (virus / trojan / adware / spyware / worms / ransomware /..... )

Avast detect all types of malicious programs

Malwarebytes does not target real virus, it also does not target script / doc / media files

Malwarebytes is certainly not light on system resources.

It is if you use the free version (no realtime protection)

That can be said for any program that isn't resident.

Because that wasn't the question that was asked.
