Avast anti-virus caused multiple BSOD

by bassn386 / February 19, 2016 7:46 AM PST

Based on several recommendations, I recently downloaded Avast Anti-virus onto my laptop. it took a day or so, but I started to get multiple BSOD's with the note: System Thread Exception Not Handled Net IO.
No data was lost, but it was very irritating. Before I came to the realization that Avast might be the culprit, I looked online for a cause. Several locations suggested my drivers might be out of date, so I updated every one. Still no change. As a matter of fact, on several occasions, the frequency of the crashes increased. I had one disastrous encounter with a program called Reimage.
I started to think about changes I had recently made and came to the conclusion that the only thing that might be causing this was the new software.
I uninstalled Avast and, Bingo! No more BSOD since I uninstalled last night.
Wondering if anyone else has had a similar experience and also would appreciate some suggestions for effective, free anti-virus software that doesn't crash your computer.

With me it works perfectly, and apparently it doesn't with you.

Free alternatives are Windows Defender (comes with Windows 10, and seems to have a reasonable quality there), AVG and Avira. Be sure you download the free versions from those last 2, and not some trial version; it might be somewhat hidden on their site. For AVG it's on free.avg.com ; I didn't check Avira.

All good here.

But the machines here are in top shape, no question about drivers, settings or malware.

It's sort of like Windows, you'll always encounter a machine that for some reason has issues. It does not mean it's a Windows or Avast issue. Finding it can be painful.

But I only have one AV product running.
Do you have more than one?
