The computer had Windows 7, and the latest version of Firefox.  

It was hacked around a week before I learned about it-  a major mess.  

I immediately disconnected it.

I'm hoping some of the experts here might have answers to a few questions:

 

First, is it safe to use the computer when it's not connected to the Internet?

Second, if I can do that ^ without any complications, would I be able to access the downloads list so I can try to figure out which download was the most likely culprit?  

Third, would there be any way I could safely remove the virus or whatever is in there?  

OR ​ is the only step I can safely take is to throw the computer out?  

 

Also, the only scan I'd used on that computer that actually removed anything was Malwarebytes, but when I checked in with this new computer it said they have a new version.  As I'm very hesitant to download anything after the experience I just had, would anyone be able to tell me where the new Malwarebytes free edition is?  

I've since read that one main source of viruses are websites claiming to scan for viruses, and it's difficult to know the difference between these and legitimate sites.

If the computer was infected with malware for a week before noticing....then reconnecting to the net to download

the programs below shouldn't cause further harm in most cases.

 

"Hacked" doesn't tell me what problems you are seeing...such as ads, search misdirects, slooooowness, etc.

 

Please use the programs below to clean, remove malware and remove adware.

 

Use CCleaner to remove Temporary files, program caches, cookies, logs, etc. Use the Default settings. No need to use the

Registry Cleaning Tool...risky. Pay close attention while installing and UNcheck offers of Google Chrome and Avast.

After install, open CCleaner and run by clicking on the Run Cleaner button in the bottom right corner.

Malwarebytes - Clean Mode

  • Download and install the free version of Malwarebytes
    Note: If you have Malwarebytes already installed, you don't need to install it again. Simply start from the next bullet point
  • Once Malwarebytes is installed, launch it and let it update its database. You might have to click on the little arrow by Scan Status in the middle right pane for it to do so
  • Once the database update is complete, click on the Scan tab, then select the Threat Scan button and click on Start Scan
  • Let the scan run, the time required to complete the scan depends of your system and computer specs
  • Once the scan is complete, make sure that the first checkbox at the top is checked (which will automatically check every detected item), then click on the Quarantine Selected button
    • If it asks you to restart your computer to complete the removal, do so
  • Click on Export Summary after the deletion (in the bottom-left corner) and select Copy to Clipboard. Paste the content in your next reply

If you are unable to run a scan using MBAM:

Follow the instructions in the thread below. Make sure to download the MBAR linked in it. Let me know if you're not able to launch it and run a scan.
