PUP.Optional.Legacy comes back after restoring win and disables everything

[GearHAVOC384]

Yesterday I scanned my pc with avg and malwarebytes because it was lagging and freezing constantly but none of them founded anything, so I tried with adwarecleaner and it found the virus (see image), but after removing it and restarting most of the services and drivers were disabled. I tried deleting the chrome extension that was marked as malicious and  restoring windows but it came back again.

Just to be clear, the line item tagged by Adwclear is just a leftover line entry in the registry.

It has no payload of any sort.  No file is involved of any sort.  It poses no danger.  It is just a "classes"\interface entry in registry.

Hi,

Just so you know, there is no need to press the "Quote" button when doing a reply.  You and I are the only ones on this thread-topic.

 

Lets do a special custom fix.  This will remove the 1 registry line tagged by Adwcleaner. 

I am sending a   custom Fix script which is going to be used by the FRSTENGLISH tool. They will both work together as a pair.

Please RIGHT-click the (attached file named) FIXLIST and select SAVE AS and save it directly ( as is) in the Downloads folder 

The tool named FRSTENGLISH is already on the Downloads folder.

Start the Windows Explorer and then, open the Downloads folder.


Double click FRSTENGLISH to run the tool. If the tool warns you the version is outdated, please download and run the updated version.
Click the Fix button just once, and wait.

 

 

PLEASE have lots and lots of patience when this starts. You will see a green progress bar start. Lots of patience. Some machines take longer than others.
If you receive a message that a reboot is required, please make sure you allow it to restart normally.

 

The tool will complete its run after restart.
When finished, the tool will make a log ( Fixlog.txt) in the same location from where it was run.

Please attach the Fixlog.txt with your reply.

 

Then you may do a new run with Adwcleaner.

Sincerely,

fixlist.txt

Hi.

Already runned adwarecleaner and the virus finally was deleted.

Thanks for your help.

You are very welcome.

Just to make clear, there was no actual "virus".   It was a harmless leftover in the Windows registry.

I am glad to hear the good news.  Glad to help you.

If you need something else, at this point, let me know.

 

Each pc user needs to practice daily safe computer and internet use.

 

Safer practices & malware prevention:
Follow best practices when browsing the Internet, especially on opening links coming from untrusted sources.
First rule of internet safety: slow down & think before you "click".
Free games & free programs are like "candy". We do not accept them from "strangers".

Never open attachments that come with unexpected ( out of the blue ) email no matter how enticing.
Never open attachments from the email itself. Do not double click in the email. Always Save first and then scan with antivirus program.

Never click links without first hovering your mouse over the link and seeing if it is going to an odd address ( one that does not fit or is odd looking or has typos).

 

Pay close attention when installing 3rd-party programs. It is important that you pay attention to the license agreements and installation screens when installing anything off of the Internet. If an installation screen offers you Custom or Advanced installation options, it is a good idea to select these as they will typically disclose what other 3rd party software will also be installed.
Take great care in every stage of the process and every offer screen, and make sure you know what it is you're agreeing to before you click "Next".

Use a Standard user account rather than an administrator-rights account when "surfing" the web.
See more info on Corrine's SecurityGarden Blog http://securitygarden.blogspot.com/p/blog-page_7.html
Dont remove your current login. Just use the new Standard-user-level one for everyday use while on the internet.
