@psikofunkster,
I read the thread and when a PC gets infected it is PIA....so emotions come out.
Perhaps the bedside manner of the Forum members is not warm & fuzzy but they know of what they talk about and that is the point.
The cold hard reality here is Avast is very good but not a complete solution.
You need to stack your security to truly have a good protection effort.....basically layered.
However, many people go from too little to WAY too much and they have software conflicts and PC burps.
It takes a lot of research on what is best, or best for you, what works well together, etc.
Also, good surfing/installing habits are really the best protection.
There are many whom will chime in BUT using Avast alone is NOT ENOUGH.....good, but not enough.
I use MalwareBytes Pro & Malware Anti-Exploit.
I don't get into the fancy Firewalls.....just use Windows.
I add CryptoPrevent.
Is this perfect.....no....others will talk about Adware Blockers, etc.....for that I use FireFox for my Browser with JAVA & Adware blockers.
Point of my config is that I don't spend my life updating, configing,.....I actually use my PC.....my families use theirs as well.
These all work nicely together and have minimal effect on PC performance.
Also, if you are set on using Admin account change your UAC to "Always Notify Me"......default is below that.
Just some suggestions.....what happened to you is in past.....can't dwell on it.....question is what action will you take moving forward.
Also, as suggested above......if you want to make sure your PC is truly clean....I highly recommend......then follow the link provided and you can even post the logs and there are fantastic virus experts in this Forum that will help.
It is worth the time.....maybe 30minutes to hour tops to run and post.
