HELP! My computer is infected with malware that fills my screen with obtrusive ads that makes it impossible to use it

[kektus]

HELP! My computer is generally normal, but once i left to go eat once, i came back to an infected laptop. My screen was full of ads and they kind of just clog up my google searches, my screen, etc. Once i came back from eating, i noticed all of my extensions were gone as well. since my computer is a lenovo laptop, i used the lenovo solution center. I did a disk cleanup, but that did nothing. Most notably, the virus tab in the solution center also says that the computer is fine, so that wasn't going to work. I then found malwarebytes and did a scan, thinking it'll all be fine, but nothing really happened. it said it found some things in my computer to quarantine and also said it removed them, but the ads were still there. please help?

Before we start please note the following:

• Analysis and research take some time, also sometimes real life gets in the way, please be patient.
• Limit your internet access to posting here, some infections just wait to steal typed-in passwords.
• Don't run any scripts or tools on your own, unsupervised usage may cause more harm than good.
• Paste the logs in your posts, attachments make my work harder and more complicated.
• Stay with me to the end, the absence of symtoms doesn't mean that your machine is fully operational.
• Note that we may live in totally different time zones, what may cause some delays between answers.

I can't foresee everything, so if anything unexpected happens, please stop and inform me!

There are no silly questions. Never be afraid to ask if in doubt!

Let's start and enjoy the fight!
