Trojan Infection

Hello,

 

A few days ago my system became infected with a Trojan horse after I inadvertently downloaded a file. My antivirus (AVG) detected it and removed it but now I have been noticing some discrepancies such as "Couldn't load plugin." error messages from online videos such as youtube and others, System Restore caused a BSOD while attempting to restore from an older back up point (newer restore point did work but discrepancies continue after restore). And the curious thing of all is when I boot in Safe Mode, the older restore point are not available, these are only available in normal boot.

 

I have a feeling AVG didn't do a good job at removing the virus or perhaps I'm jumping the gun here. Either way, could I provide you guys with a log file to have one of you fine gentlemen check it out?

 

Thanks!

AdwCleaner

 

# AdwCleaner v6.030 - Logfile created 28/10/2016 at 22:28:27

Sophos?

 

No threats discovered with Sophos so it didn't give me a log report (details button was grayed out).

Your computer is clean

1. This step will remove all cleaning tools we used, it'll reset restore points (so you won't get reinfected by accidentally using some older restore point) and it'll make some other minor adjustments...
This is a very crucial step so make sure you don't skip it.
Download DelFix by Xplode to your desktop. Delfix will delete all the used tools and logfiles.

Double-click Delfix.exe to start the tool.
Make sure the following items are checked:

• Activate UAC (optional; some users prefer to keep it off)
• Remove disinfection tools
• Create registry backup
• Purge System Restore
• Reset system settings

Now click "Run" and wait patiently.
Once finished a logfile will be created. You don't have to attach it to your next reply.

2. Make sure Windows Updates are current.

3. If any trojans, rootkits or bootkits were listed among your infection(s), make sure, you change all of your on-line important passwords (bank account(s), secured web sites, etc.) immediately!

4. Check if your browser plugins are up to date.
Firefox - https://www.mozilla.org/en-US/plugincheck/
other browsers: https://browsercheck.qualys.com/ (click on "Scan without installing plugin" and then on "Scan now")

5. Download, and install WOT (Web OF Trust): http://www.mywot.com/. It'll warn you (in most cases) about dangerous web sites.

6. Run Malwarebytes "Quick scan" once in a while to assure safety of your computer.

7. Run Temporary File Cleaner (TFC), AdwCleaner and Junkware Removal Tool (JRT) weekly (you need to redownload these tools since they were removed by DelFix).

8. Download and install Secunia Personal Software Inspector (PSI): http://secunia.com/vulnerability_scanning/personal/. The Secunia PSI is a FREE security tool designed to detect vulnerable and out-dated programs and plug-ins which expose your PC to attacks. Run it weekly.

9. (optional) If you want to keep all your programs up to date, download and install FileHippo Update Checker.
The Update Checker will scan your computer for installed software, check the versions and then send this information to FileHippo.com to see if there are any newer releases.

10. When installing\updating ANY program, make sure you always select "Custom " installation, so you can UN-check any possible "drive-by-install" (foistware), like toolbars etc., which may try to install along with the legitimate program. Do NOT click "Next" button without looking at any given page.
