STC Virus

I recently got some software called "Second Thought" or something.  I'm not sure because I deleted everything.  I went to Regedit and removed all of the stuff.  Basically, my antivirus program, PC-Cillin, identified it as STC, a virus.  Then, it quarantined it and I removed it.  However, my PC is now acting weird.  PC-Cillin's web trap thing keeps popping up and I am still told I have the virus.  It's been a bit less than an hour.  I did nothing to cause this.  How do I get rid of this thing?

Thank you,
Radomir Jordanovic

Hi radomirthegreat,

STC is an adware ... get ad-aware from lavasoftusa.com and run a full system scan

Cheers!

I have Ad Aware, and PC-Cillin has identified 6 viruses.  They're all pretty much that horrible STC thing.  By the way, I deleted STClient from the registry.  Is that all right?

yes... you need to kill a few running tasks ...
http://www.safersite.com/PestInfo/s/second_thought.asp

run a minimal set of services .. shut down everything that you do not need ...
next open task manager and kill tasks mentioned above ...
run a full system scan of ad-aware and antivirus

Also double check for viruses using one preferrably two of those online scanners I listed.

Thank you.  I'll see what I can do.  Isn't, however, the threat over?  The files have been quarantined and removed?  The PC is back to normal.  I even put it on "lockdown" (PC-Cillin feature) during the scan.  I think it should be all right now.  I take extra precautions not to run any weird programs on my PC, like Kazaa Media Desktop and such.  I don't think I'd ever allow anything to happen to my great PC.  I'll soon get DiskKeeper 8.0 to keep up this great speed.  Could you warn me about any problems I'll soon face?

By the way, thanks for the extremely fast responses!

radomirthegreat,
> I take extra precautions not to run any weird programs
Is always a good idea...

You need to remove the quarantined files from your system ... even though they are not a threat but better safe than sorry...
If you have already performed removal and all steps mentioned above, you are in all probabilities safe

Keep running all the utilities listed in this question until it they all come up clean.

Don't let sites download anything you are not sure of. You should get a prompt when a sited wants to install something on your machine. Only click yes if you absolutely sure of what it is the site is wanting to download.

Make sure you have your virus scanner set to scan your incoming and outgoing mail. Always have your virus scanner to auto protect. This will catch almost all viruses before they have a chance to implant themselves on your machine.

Keep you virus scanner definitiions up to date.

Also plan to use personal firewall also so that no one dare to intrude on your system. if u already have firewall then ignore this suggestion.

I never download anything from sites.  I ran that eTrust Online program and I came up with two Temporary Internet files.  All of my temporary files are now gone!  I'll keep running the programs and see what happens.
