My PC suffered an attack recently that threatened to get out of hand. Would my credit card details and other sensitive information be stolen? Luckily I managed to fix the problem quickly.

The most worrying problem was the inability to use Windows Updates. My antivirus package (Norton Antivirus) detected trojan.VUNDO. It reported the problem was fixed, but then the problem returned immediately.

Your computer could be farmed for sensitive information, such as credit card details and passwords. A criminal knows that if a PC is cut off from software support, either antivirus or operating system, he can exploit that at his leisure.

It is essential that when security updates become disabled you fix this problem as soon as possible. Do not postpone this even if the computer is operating normally in other ways. If you choose to ignore it the results could be disastrous.

The first thing to try is to download the updates manually, but in my case this was knocked out as well. My pc was totally cut off from help from the software vendor.

The next resort was to go to the Windows forums and discussion groups to find an independent route to getting a fix. A report of the same problem was quickly found after doing a search of the discussion group. A software package was recomended that could deal with this problem. The package in question had the major advantage that it was free! It is called Malwarebytes’ Anti-Malware 1.31 and it can be found at http://www.malwarebytes.org/ and I strongly recommend it.

Updates are brought out every few days so the supplier is responding to the latest threats very rapidly. There are also paid versions which are even more powerfull.

There is a continual battle going on between criminals and the Internet community. Online fraud is always a potential problem for anyone who uses the Internet. However, it is good to know that companies like Malwarebytes are there providing solutions. They definitely knew how to undo the VUNDO for me!
