a reference to c5y.exe on Google, so it is not a common malware.
You need to approach this sytematically. Obtain a suite of anti-malware programs, install each and update their definitions immediately, then scan your computer.
This is what I have said to many other people. Other members of these forums have said similar things;
"Try an online scan for malware at http://housecall.trendmicro.com and set it to "fix all problems" and run the scan.
Do you have a firewall installed on your computer? If not, I suggest you goto http://www.zonelabs.com and download and install their free ZoneAlarm firewall. This will help protect your computer from hackers.
Also, you need an antivirus program. I suggest AVG7, a free program from http://www.grisoft.com.
And an anti-adware program. Free program is Ad-Aware SE Personal from http://www.lavasoftusa.com
And 2 spyware programs, Spybot Search and Destroy from http://www.safer-networking.org/
and SpywareBlaster from http://www.javacoolsoftware.com/spywareblaster.html
Make sure your Windows Operating System, (OS), is up to date. To do this, goto Start, and click the ?Windows Update? link. Beware, if you have not been to Windows Update before, there may be a lot of critical and other updates your OS needs to download.
All of these anti-malware programs (except the firewall), need to have their virus/adware/spyware definitions updated as soon as they are installed, and then each one used to scan your computer.
If you can do all this, and you still have the problem, re-post your problem in the Virus and Security forum".
I have a weird spyware prob. I've run Webroot spysweeper, I've cleaned the registry and I still don't know how to get rid of this.
The issue is that I have a pf file in the Windows prefetch folder called c5y.exe Whenever I'm online, I'll get the random popup linked to this particular file. Whenever its deleted, it will come back the next time I'm online. No programs seem to be able to find it, and I can't seem to get rid of it. Can anyone help???
