Hope, I am using ESET NOD32 Antivirus and Malwarebytes Anti-Malware.  It all seems to work just fine.  I am supposed to run M (launch it) about twice a week to do a full scan if I am on the computer a lot.  A full scan is nowhere near as slow as Norton 360 used to be.  ESET runs all the time.  I can hand launch it, but presumable that should not be necessary. 

Every time you plug in a new disk, or new USB stick ESET asks if you want to scan it.  Sometimes yes.  Sometimes with both. 

I have heard the same thing as you re AVAST.

Malwarebytes Anti-Malware seems common in a backup mode. 

My pro friends change systems all the time.  System of the month kind of thing.  And they each will have different systems.  They do work.  They understand things better than I do.

You both might need to have your computer checked for viruses.   Don’t say, I have xxxx anti-virus so I can’t have a virus.  Sure you can.  All anti-virus packages have vulnerabilities. 

Most of my computer professional friends have two anti-virus packages running.  One such as Avast as the main line of defense and Malwarebytes  Anti-Malware sitting quietly checking everything you do or anything that is trying to come on board.  That is just one example.  Most of the time both are discreetly unobtrusive.  Occasionally you will get a notice that something nasty had you under attack, but has been blocked.    

Even so you can still get viruses.  Unless you are expert at cleaning this stuff up, seek expert help.  Rent-a–Geek cleaned an unreal batch of nasty stuff from a lady friend’s computer.   I had Dell help me clean up my hard drive once.   They cleaned out about 10 nasty malware of various sorts.  Cost me about the same as a new computer of the same capability (it was 5 years old).   So, if your computer has a bit of age you may just want to replace it.

Are your crucial documents (or whatever) backed up?  If not can you live without them?  That may get involved in your decision. 

The place I purchased my last computer from was able to move all my stuff from my old hard drive without moving any malware.  It only costs money.
