Win32:Malware-gen infection. Got quarantined but I'd like to make sure I'm clean

I was visiting a pseudoscientific, psychologic site the other week, about hypnosis and other theories (I’ve studied psychology and the subject catched my interest). Upon entering, the site seemed to be old and hasn’t been probably touched in years. I would’ve been better to stay away, because upon entering the site I got an Avast popup of prevented threat (three blings, which meant three pop ups)

It read:

Threat prevented.

Object:

http://blog.mindcontrol101.com/wp-content/uploads…

Infection:

JS:Includer-BOF[Trj]

Process:

C:\Program Files (x86)\Mozilla Firefox\firefox.exe

Btw, Avast online security declared the site, http:mindcontrol101.com clean. Weird, because Sucuri SiteCheck noticed that the site had malware javascript (should’ve checked with it BEFORE entering the site lol )

I instantly swtiched off from the internet and made a smart scan with Avast, then Malwarebytes scan after it. The computer seemed clean, no detections. I made Avast quick scan too, no detections. I also erased the temporary internet files using both Firefox and cleanmgr.

I decided to get back to the internet just to update Avast into it’s latest version. It was already its newest version so there was no need to worry about that.

It was beginning to be late so I decided to do the full system scan the next day.

While remaining offline the next day, I did the Malwarebytes scan another time (it was clean) and Avast full system scan after it. I found out there was a malware in the system. I don’t know if it was because of this site I had visited or some other. I hadn’t done a full system scan in a while, it could be because of this too.

While Avast continued scanning the system I wanted to see if any alters had been made in the system files. I ended up eventually opening the Temp.file but closed it instantly afterwards, realizing that the malware could be from this very file.

After the scan had finished I could see it unfortunately was:

File name:

C:\Windows\Temp\862.tmp.

Threat level/Seriousness:

High

Condition/Status:

Threat: Win32:Malware-gen

I managed to contain the threat into Avast quarantine.

After it, another full system scan. No detections.

I restarted the computer, went online and one more full system scan and Malware bytes scan. Both were clean. No detections.

Still, I remain suspicious. Could there still be a virus in my system? I’d like to make sure I’m clean. Please help me double the check the system.

Thanks!

One more note:

Is it safe to empty the temporary files using Cleanmgr? The virus having come from the Temp.file, I’m pondering if this is the correct thing to do (Temporary file is 543 mt in size currently, I’ve never emptied it and I’ve used the computer for a year and a half now.)
