@Jack: Thanks for the assist! Many fine points made there.
Hi Adam: That's a great program which many of us use here regularly. However, there are many categories of malware that are not picked up by Malwarebytes (MBAM) as that program only picks up Spyware viruses. There are Rootkit viruses, Trojan viruses, Day-Zero Attacks, Phishing E-mail viruses, E-mail worm viruses, etc. etc. Jack's question you didn't see to answer, unless your Malwarebytes found zero spyware viruses. This is very unusual for most infected computers, even for computers infected with different types of viruses. Some spyware viruses are almost always found on computers we regularly repair.
If no viruses were found by MBAM, you can visit
trendmicro.com and use their free online virus scanner called HouseCall. Scan/remove all viruses found. Next, download their RootKitBuster which checks for Rootkits/Bootkits category of viruses which cannot be found by regular AV programs or MBAM as they hide in the hidden system partitions of your Hard Drive.
Also, you didn't mention whether or not you were able to check your browsers and Internet in Safe Mode as suggested by Neem in
Post #2. Were you able to do that, Yes or No?
If the problems persists after this further cleaning, and you are unable to get into Safe Mode on your laptop for whatever reason, you should consider Jack's suggestion of
"rolling back" your Windows on that laptop to a point in time prior to when this problem occurred. If it's virus/malware related, or Windows corruption related due to a bad program installed, or from a recent update,
System Restore is your best bet. With that suggestion in mind,
we strongly suggest that you FIRST BACKUP ALL OF YOUR PERSONAL DATA TO EXTERNAL MEDIA! THIS WOULD INCLUDE YOUR LIBRARY FOLDERS FOR DOCUMENTS, PHOTOS, MUSIC, VIDEOS, AND ANY SAVED E-MAILS OR ATTACHMENTS IN ORDER TO AVOID IRRETRIEVABLE DATA LOSS!!
Should all of that fail, you might have failing hardware and should test it yourself or pay a Tech to do for you. If you decide to DIY on the hardware testing, then take a look at my free
TROUBLESHOOTING GUIDE here:
Windows 10 - Unclickable Task Bar
If any failed parts are found or you find you must reset or reinstall your Windows, and you've never done those things before yourself, you may have to take apart your laptop for example, we urge you to consider taking it to a licensed Computer Pro and paying to have that done professionally. Remember that laptops are 3x more difficult to service than regular desktop PCs.
Hope that proves helpful to you.
Best of luck,
