How to clean my Computer

[Fury]

What is the best way to clean my computer
I want to get the best out of it and make it as quick as it can be but atm its kinda slow and i want to enhance this
I have a load of shit on it that needs to be cleaned up and my web search is fucked as well which i cannot seem to find to change it back to google
Any recommendations peeps?

1st thing I would do is run CCleaner on your computer to try and boost it a bit, next I would run Windows Security Essentials to scan for any viruses, after that head to system properties ---> Performance and tick the Adjust for best performance option.Check your task manager for any unneeded processes running.What Browser are you running?
Also, if all fails I would personally do a completely new install of Windows (assuming that is your OS) on your computer.

also something else, it wouldn't hurt to upgrade the ram on it, but if its a desktop you could also upgrade the CPU and Graphics card which would give it a good boost, you can upgrade the cpu on some laptops, but not all.
Also If you don't have one/if you can I would upgrade to an SSD

I heard if you throw it out the window then put it in the oven it runs 15x faster.

Hm try heading here chrome://settings/searchEngines and  see if it lets you change the search engine, if it's not there then add it manually by putting in Google for the name, Google.com for keyword and {google:baseURL}search?q=%s&{google:RLZ}{googleriginalQueryForSuggestion}{google:assistedQueryStats}{google:searchFieldtrialParameter}{google:iOSSearchLanguage}{google:searchClient}{google:sourceId}{google:instantExtendedEnabledParameter}{google:contextualSearchVersion}ie={inputEncoding}  for URL (I just c & p from my side)

CCleaner, Avast, MalwareBytes

Defragging your hdd is always a good option, so is an SSD.
