Hello. I downloaded Avast free version a few days ago. Since then every 2 to 3 min I keep getting messages that it is being blocked. Is there anything I can do for this? Thank you.

Hello. Thanks for the assistance. This is my 1st time doing this so if anything is incorrect please let me know & I will ltry again.

Here’s the last one.

looks okay and it seem you have a Siref rootkit infection :-\

i also see that you have avast and McAfee installed…
never install multiple AV programs, it will slow down your machine, give mysterious windows errors, false positive detections etc etc

so you need to uninstall one, and then run a removal tool to clear any leftover files that may conflict

you find the tool here.

magna86 will remove the malware when he is back later today

How is your computer running now?

It’s running better than it was before. My web pages are loading faster & it doesn’t take as long for it to start up after a reset.

Re-run OTL and click on CleanUp! button.

You will be asked to reboot the machine to finish the cleanup process, choose Yes.
After the reboot all the tools we used should be gone.
Note: Some more recently created tools may not yet be removed by OTL. Feel free to manually delete any tools it leaves behind.

K. Just did it. :slight_smile:
