I am having a problem with several Trojan viruses on my computer.
It was not detected by my avast, but when I ran malware bytes it came up with several different Trojans.
The only one I was able to remember was a medfos Trojan.
My computer is no longer able to access the Internet as it keeps displaying an error
And now even basic things like trying to open my malware bytes log freezes the computer.
Any help with this would be appreciated , however I may have trouble running scans as my computer just keeps freezing.
Please attach your logs. (AdwCleaner, MBAM, OTL and aswMBR…!!)

: Keep Java Updated :
WARNING: Java is the #1 exploited program at this time. The Department of Homeland Security recommends that computer users disable Java
See this article and this article.
I would recommend that you completely uninstall Java unless you need it to run an important software.
In that instance I would recommend that you disable Java in your browsers until you need it for that software and then enable it. (See How to diasble Java in your web browser and How to unplug Java from the browser)
Now that you are clean, to help protect your computer in the future I recommend that you get the following free programmes:

Malwarebytes.
Update and run weekly to keep your system clean
Download and install FileHippo update checker and run it monthly it will show you which programmes on your system need updating and give a download link
If you use on-line banking then as an added layer of protection install Trusteer Rapport
It is critical to have both a firewall and anti virus to protect your system and to keep them updated. To keep your operating system up to date visit
