Working online can really expose your laptop into a lot of online threats like malwares and viruses. A few days ago, one of my friends suddenly had problems with her blogs because it was attacked by some kind of virus and until now she wasn’t able to fix things yet. She warned all of her friends to make sure their laptops are protected with Avira Antivirus. They have a free anti virus software that you can use for your laptop or your Mac. The best part is they offer customer support in any case you will encounter some problems. Remember to keep your laptop protected all the time!
