Avast Warning : Malicious URL Blocked
« on: April 19, 2014, 02:45:24 PM »
Avast keeps giving me this warning when using Chrome. Attached is a screenshot of the warning that appears.

I have been trying alot of things lately and nothing seems to work. Any help would be appreciated.

Hi maRED,

please go Here and attach OTL, Malwarebytes & aswMBR.

It appears, you are using an outdated version of Avast!. Can you tell me your current version (Program). THanks

It was a chrome addon Vonteera Safe ads and I just killed it :)

In that case methinks I will send you on your merry way :)

Subject to no further problems   :)

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:

Download and run Delfix



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



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.
