Trojan Alert

Hello folks,
Yesterday I downloaded the following program (Returnil Virtual System). Before installing I scanned with Avast and AVG. Passed. After the install my computer just started acting strange. My firewall was disabled, Word progam was not working properly, start up was extremely slow. I immediately proceeded with unistall and Avast picked up the following trojan horse:Nimosw-B. Keep your eyes peeled guys and gals.

I meant to include this with my first post.

Returnil Virtual System is not the culprit, must be where you grabbed it from or it's just coincidence or it's a false positive. Who would infect their own for sale product?

 

Not familiar with the software, but guessing it may be a false positive...would wait for a Mod or owner to reply. My AV picked up a MSN game .dll as a Trojan a few weeks ago, it was a false positive.

 

I would like to thank each of you for your replys. Perhaps it was a false positive, but that doesn't account for the way my computer messed up after installing. I'm curious, what are the files that are quarantined in Avast after being detected? Also, it was not a paid program, but the free personal. Thanks again folks.

Perhaps it was Returnil Virtual System itself that did the deeds, can you restore to before that point and install it again to see if it's the culprit or not.

 

Most likely you had Avast processes running during the install and then installed another Anti Virus program with active processes running.

It would be like having one guard dog and then putting another guard dog in the same yard, they would fight when they detect each other - hence the PC going nutz trying to figure out which program/process to follow. This behavior is by design or nature of the beast and to protect you.

Anti programs often detect each others files due to the type of software. Which is why you don't run two at the same time.

Did you have a virus problem prior to installing Returnil System, if so, then we need that info to help you.

Looking at the files Returnil has been downloaded 270,000 times, so if there was a problem it would have been noticed.

 

Hmm, true enough with that volume of dl's.

 

Hello everybody! I use Returnil and if you are not familiar with the program it can seem like things are going south on you. Downloads and installs disappear with a reboot if you don't use the virtual drive or at least a drive other than the drive being protected. I hope this helps.
