Anti-Malware Tools for Your Flash Drive

Most malware will block the installation of scanners or will shut down any installed scanners. Some malware will stop you from connecting to security vendors websites, meaning that you be unable to download either the security tools or updates for them. It’s sometimes possible to “trick” the malware scanner by renaming the executable of your security application, but this is not a foolproof method and does not always work. If ever you come across such a situation, having these tools on your portable device will really help:

Why Portable Tools are Useful?

When I purchased my laptop from Dell in 2006, I had the option to buy the laptop with hard drive of between 60GB and 120GB. I decided on 80GB to keep the weight down. The laptop is almost 3 years old and the 80GB hard-drive has 40GB of free space left. Upgrading to 100GB or 120GB is a solution - but an expensive one - so I decided to use a portable device to store some of my data. Also, I decided to start using portable applications instead of installing on my laptop, which saves some addition disk space.

Portable applications are handy not only to reduce disk use, but also if you have more than one computer or if you need to fix somebody else’s computer.

Below are the best portable security tools.
