Why does my browsers shutdown when i try to download anything.

Hi and welcome to SevenForums,
What malware was found and with what utility ?
If your having issues downloading these scanners use safe mode with networking and run them twice once in s.m.w.n. and booting normally,
Review Jacee’s instructions to run Adwcleaner here post #7,
Ignore the title of the thread,

You can use these free tools to see if they find anything,
Manually Update them before running full scans,
Try not to use your computer while the scans are running, (one at a time of course).
See this tutorial on how to download and run Malwarebytes,

Also use the Custom scan option not the Threat scan,

Please Do Not clean/ Delete or Remove Any detections before posting the scan results first before review especially Malwarebytes,

This one is the longest up to 4 hours, the others are only about 45 minutes,

Hi and sorry I should of posted these directions.
Safe mode with networking,
Shut down your machine, Unplug-Hold the power button down for 30/45 seconds (Power Drain)
If a laptop remove the battery and do the above,
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
