Avast blocked by group policy

Viruses and worms
1

Hi guys,

My avast program won’t run anymore, it says it’s blocked by group policy. I actually have malwarebytes which I have just tried to use too, but that was also blocked for the same reason. If I try to do anything like uninstall these, I’m told I don’t have sufficient administrator access… Clearly I have some sort of horrible virus on my laptop but it seems there is no simple fix from looking at similar complaints on this forum.

I’m usually quite good at sorting issues with my computer myself and finding fixes but this one has left me clueless!!

Please please, any help anyone can give me would be great!!

Hi there you have a nasty bit of adware, lets kill it :slight_smile:

Please download Farbar Recovery Scan Tool and save it to your Desktop.

Note: You need to run the version compatible with your system. If you are not sure which version applies to your system download both of them and try to run them. Only one of them will run on your system, that will be the right version.

[*]Right click to run as administrator (XP users click run after receipt of Windows Security Warning - Open File). When the tool opens click Yes to disclaimer.
[*]Select additions at the bottom
[*]Press Scan button.

https://dl.dropboxusercontent.com/u/73555776/frst.JPG

[*]It will produce a log called FRST.txt in the same directory the tool is run from.
[*]Please attach both logs generated.

Subject to no further problems :slight_smile:

I will remove my tools now and give some recommendations, but, I would like you to run for 24 hours or so and come back if you have any problems

Now the best part of the day ----- Your log now appears clean :thumbsup:

A good workman always cleans up after himself so…The following will implement some cleanup procedures as well as reset System Restore points:

Click Start then Run.
On Windows7 or Vista you may use Start Search field if Run is not available.
In the box copy/paste the following command:

ComboFix /Uninstall

Note that there is a space between " ComboFix " and " /Uninstall " .

Then click OK (or press Enter ).
Wait for the uninstall process to complete.

Download and run Delfix

: 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

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:

CryptoPrevent install this programme to lock down and prevent crypto ransome ware

https://dl.dropboxusercontent.com/u/73555776/CryptoPrevent.JPG

Malwarebytes.

Update and run weekly to keep your system clean

It is critical to have both a firewall and anti virus to protect your system and to keep them updated.

To learn more about how to protect yourself while on the internet read this little guide Best security practices Keep safe :wave:
