browser keeps crashing

Hi ro187 and welcome to Seven Forums!

Did you get an antivirus product only after you noticed you were infected? I mean if you didn't have one before that? Viruses and malware can cause all kinds of strange problems, and it's often not enough to only let one antivirus product clean it up.
If you haven't done a full scan with BitDefender, I suggest you start with that.

Then I suggest Malwarebytes Anti-Malware Free
Go to settings and check the "Scan for Rootkits" option to also try and find hidden malware:

You could also try this to perhaps see if there's any sign of malware present: https://www.sevenforums.com/tutorials...s-50-av-s.html

Should i delete all threats detected by MalwareBytes?

As a general answer Yes, but if you're unsure you can post the scan results log here so we can help you decide.

Safe mode with networking,
Shut down your machine, Unplug-Hold the power button down for 30/45 seconds (Power Drain)
Power up and Tap the F8 key continuously until you see a black page with white text,
Use the down arrow key to toggle to safe mode with networking/ hit the enter key.
Login as usual and download the scanner,
Post the scan results,
Cheers.

Hi,
Very weird,
Restart normally then run the scanners,
The View problem details might shed some light but I doubt it they usually contain the obvious exe file crash :/

My first thought would be to uninstall BitDefender ?
What antivirus and or security suite was installed before all of this started ?

@ThrashZone From a previous post:

"The only antivirus I had prior to being infected was AVG. Afterwards I used Kaspersky rescue disc to scan and remove threats. Then bought BitDefender, installed, scanned and removed 4 viruses. My usb's are no longer affected."

Ha thanks Tookeri missed those entries

Were these uninstalled properly ?
