Malware is any malicious software that is designed to harm both and user and computer. Since the Internet is the biggest source of malicious software and every time you browse a website it’s like opening your front door to the world and inviting strangers in. The venerability is real and you need to protect your computer and the personal information that it contains. There are many good software companies that provide free protection software. Just search for free malware removal software and you will find some of the best companies, such as Malwarebytes, Avast, Avira, AVG, and several others, offering free versions of their best software. These free programs all use their best commercial malware scanners to find and remove offending software. They also offer website and email scanning and most offer daily updates and scheduled scanning. I personally have been using AVG for several years now and believe it is still the best out there. Malwarebytes is also becoming a favorite and has one of the best scanners available.
You really can’t be too careful. The loss of valuable personal information could be disastrous. Also backing up important data to external devices is a must. Flash drives have become very reliable and their increased size have helped them to become a great alternative to tape and external hard drives. The only problem with external devices is they all have life expectancy so nothing is permanent. Cloud or Internet backup services have become a great alternative with their reasonable monthly costs. I still keep my important data on a second partition, which I backup to an external device or devices depending on the value of the data. For client and business data I usually keep 5 full backups, after finding some of my backups unusable. Tapes and external hard drives are cheap so there should be no reason for last data.
Be sure to check out the free malware removal software that has some very high reviews. Just a little research from user reviews should help convience you that some of these products might be worth checking out.
