My Norton picked up a virus

Question

Trojan.Byteverify

I ran a virus scan using free anti virus and it detected four Trojan.ByteVerify viruses. Is there any free/simple way to remove it as my norton is free and it doesn't enable me to do so.

Answer 1

Uninstall Norton, Download Avast

Download SuperAntiSpyware

Restart your PC in safe mode, and run a full scan with both.

While in safe mode, you may also want to have a look at your start up items by using msconfig.

Be careful with the items you uncheck, you can have a look here to see if they are necessary

You should also have a look at your IE Add-ons while in safe mode.

Disable any you do not use.

After you reboot back to normal mode, download and install ccleaner to fix any registry problems and clean up old temp files.

Answer 2

its not simple...

but you have to read the removal process by clicking on the threat details..

and delete all the registry keys they tell you to..

the reason this is, is because.. the software will delete the program, but the hidden registry keys, will just bring back the malware...

the worst case senario is.. you might just want to.. create a back up.. of all your files that are important.. and format your hard drive..

Also download and run Windows Malicious Software Removal Tool:

Answer 4

AVG Anti-Virus software.

Answer 5

A very good, free anti-virus available to download is AVG 8 Anti-virus:

http://www.free.grisoft.com

And for any spyware problems, get SpyBot - Search and Destroy:

Both are free, as powerful as paid programs, like Norton and McAfee, and don't use up as many resources.

Just boot into Safe Mode (Press F8 when turning on the computer) and run full scans.

Hope that helps.
