#3 – Virus Removal
Problem: While some viruses can be really damaging to your computer, others will run in the background, seemingly harmlessly but will take up your computer’s resources and slow it down.
Solution: Download, install and run a good free anti-virus programme. Two of the best free anti-virus programmes at the moment are Avast AntiVirus and AVG AntiVirus, which both offer real-time protection and don’t take up too much of your machine’s RAM like some other anti-virus programmes do.
Tip: When downloading any free software, make sure you do not install any additional software that is offered as part of the package; you don’t need them.
