1 day later, norton got removed, empty norton folder

put in avg, said trojan horse generic30.wav found, removed.

came back again.

question:

1.  do i need to turn off system restore; afraid that if it crashes, i don't have any restore point to boot up the computer.

2.  does anyone know how to remove the trojan.  I bought norton antivirus 2013.

thanks.

Try Sophos Anti-rootkit. It is free.

Then try the combination of MalwareBytes.org and SuperAntiSpyware.com.

Malwarbytes does NOT seem to get it all on its own, probably because of the trojan has a rootkit component.

I did not find a removal tool specific to that trojan.

When done, clean install the security suite of your choice.  I do NOT recommend Symantec/Norton nor MacAfee. AVG is working well for a few of my clients. Other good products are ESET (my personal favorite), Trend Micro (especially in the corporate environment), FSecure and some others. While I have had good luck with Kaspersky, and he is a stellar malware/security expert, I have concerns about his corporate/political environment.

i ran malwarebytes, & spy bot & norton.  i will try the superantispyware.com & kaspersky.  

the computer also had a blue screen and created a dump but after that, it boots up ok.  do i need to reinstall or repair the windows 7 home premium?

If all else fails, run Combofix, if necessary in Safe Mode.

Did you run the anti-rootkit tool?

After running the anti-rootkit you should run scans with MalwareBytes and SuperAntiSpyware again.

The malware scanners I suggested do scan the registry and remove/correct issues found with your consent.

I would run a combination of antivirus and antimalware. For the latter I would recommend Malwarebytes Pro if you want real time protection. At home I have had great experience with Eset NOD32 while at work I have had great success with Sophos and AVG combined with Malwarebytes Pro. Usually it's the personal experience that counts when talking about AV. Opinions differ greatly.

As for a stand alone registry cleaner, malware unrelated; Piriform's CCleaner is a great little utility.

As noted earlier, my favorite is ESET Security Suite and has been for  a couple years.  My second choice is FSecure. The owner of FSecure and lead developer is just about the most experienced coder in this sector. He predates the better known coders. He has always been a solid tech and made solid applications.

I concur with EMJSR, CCleaner is a cool utility. However, I normally use it when in need or suspicious.

Unless you have more errors or anti-malware traps, it sounds like you are ready to get your new security suite, rid of any remnants of Symantec and install the new suite.
