There are many software sites that proclaim that their software is the top rated antivirus software and is the only one available that will block any and all incoming viruses and malware threats to your computer. The truth is that no PC security software maker can make that claim. The problem is that viruses are invented faster than the R & D (research & development) departments of the large software companies can identify and write code to block them. Most of the top rated antivirus software available will only block or, in some cases, disable the virus.
Most really malignant PC viruses are so invasive that they actually tag on to hidden portions of your computer, your installed software, and your saved files. That is why when you take a computer in for repairs at places like Best Buy or one of the other big retailers that have computer repair departments they will usually tell you that your entire computer has to be scrubbed. That means that all files need to be individually scanned for viruses and the clean ones are then saved. The rest are lost, along with your operating system and any installed software. Your OS is then re-installed but unless you have your program disks with the registration codes, you will need to buy those programs again.
One of the top selling and top rated antivirus software programs available is Norton Antivirus. One would think that by shelling out a hundred bucks for the latest Norton Antivirus program that you would be able to prevent or block viruses from infecting your computer. You would be dead wrong. Norton is good for catching some Spyware such as tracking cookies, but in my hard-earned recent experience, Norton did nothing to block or prevent a Trojan virus from infecting my laptop.
One day I logged on to find that my browser was literally hijacked by this insidious virus which comes disguised as a security alert. Heres how it works, you are browsing the web using Mozilla Firefox or opening an email sent to you from someone you think is a friend. When you open the attached Powerpoint which usually has a very mundane and safe theme, like Songs of Springtime or Worlds Most Beautiful Sunsets or some other such drivel, the actual file you download will carry the virus straight into your computer, where it will then block you from controlling your browser. Every time you try to open a new browser window you will get this security alert telling you that you need to click here to download their free antivirus software. When you click on this, it either totally crashes your computer, or just will continue giving you pop-up windows. Not even the top rated antivirus programs in the world will help you with these and I know that for a fact because I tried them and they failed, especially Norton.
There is an alternative to these so-called top rated antivirus software programs that has given me great results. It is called Combofix and you can find it by googling the name and downloading the program. Since your browser is hijacked, you will have to download it from another computer and put it on a flash drive. Insert the flash into your computers USB input and use the program to clean your computer. It will take a while and you may have to run it twice, but it really works and a lot better than the top rated antivirus programs out there on the market. Best of all it is totally free.
