hello my win 7 comrads....i installed win7ult on my pc a couple months ago and its great but i recently got a trojan and tried minipulating security setting and systems scans to fix my problem but to no avail. the first sign....win sidebar gadgets stop displaying correctly...then...i am not ABLE to download much of anything(not allowed)....i uninstalled AVG a.v. and installed Avast and it found the trojan...a file i suspected all along..."Qfygia.exe"...cant find any info online about it.....avast shows it to be related to blogdemand(dot)com...i cant even open that page...my a.v. blocks it...ANYWAY....im thinking ill reinstall windows to smash that thing and what i need opinion is....SHOULD I REINSTALL OS OR ANOTHER METHOD...i have a lot of programs on there i will need to reinstall......thanks in advance.

In view of what you've found I'd be inclined to reinstall Windows.

I realise that re-installing your programs is time-consuming, but you will have a clean system.

Once you've done it, create a complete backup of your system by creating a system image with either the Windows backup utility or a third-party program such as Acronis.

thanks for the quick reply....thats kinda what i thought too....but wanted confirmation.....I dont have a restore point or system image or i can just restore my pc....but i dont have it.....too bad....

You're very welcome.

Just make sure you create that system image when you've re-installed everything, it'll pay off in the long run.

I'm inclined to agree with seavixen ... a clean install is probably the safest way to make sure the malware is removed. But you could also try some of the recommended scanning tools just for the heck of it to see if they can detect and remove the problem(s). They're all free.

Malwarebytes : Malwarebytes Anti-Malware is a free download that removes viruses and malware from your computer

HouseCall - Free Online Virus Scan - Trend Micro USA

Hitman Pro 3 - SurfRight

And if you're still using the HP, you should have a hidden recovery partition that will return your machine to factory specs (just like the day you brought it home.)

i tired m.s. malicous already....nada...i tried the malware bytes....the folder was empty...when it downloaded.....nothing....i was getting a lot of pop ups before i switched antivirus programs(popups after infection)...now pc runs fine but wont open some folder.....wont install some downloads or updates and windows sidebar dont display correctly....other than those things its zippy.

Wanna Thank All of You.....formatted primary hard drive and fresh installed win7ult this morn....running like a champ....now just installing all of my most used programs....thankfully i had all most important docs backed up....thanks again.
