Virus Problem - Please help?

Liam, I don't care what anybody says, the use of TWO anti-virus programs on ONE system is not advisable. The use of TWO Firewalls is not advisable (with the exception of a firewall on your PC and a separate Router firewall). You can have as many anti-malware programs as you want as long as only ONE is using real-time detection. Why? Because your system will slow down considerably and even have lock-ups and crashes. Two anti-virus programs will compete with each other (and they most definately DO). All anti-virus/malware programs use different formula's for detecting the bad stuff so different programs will yield different results. That is why it is a good idea to run several anti-malware programs to see what each finds. Also, beware of "false positives". AVG is known for many false-positives (when hueristic scanning tries to identify suspicious files by use of pattern recognition). These files may not be virus's at all, but are flagged as such just to be safe. For free anti-virus programs I have found Alvira's "AntiVir" to be excellent. It's the program I install on all Client's PC's after I build them. Avast is also much improved from a few years ago. There is nothing wrong with the FREE Microsoft Security Essentials either. Personally, I use Norton 360. I have had a "HATE" relationship with Norton over the years due to the immense bloat and invasiveness of their software, but it seems Norton got the message and their new 360 program is lean and mean and very, very effective. As a Comcast subscriber, I get Norton for free. I would check with your subscriber to see if they offer a security suite for free. Most ISP's do. One last thing--if you are experiencing a virus that simply will not go away (meaning your anti-virus program gets rid of it but it keeps coming back), then the virus is also living within System Restore. You get rid of it and System Restore puts it back. Many virus's are designed this way. You would need to disable System Restore (which deletes ALL system restore points), then run your virus scan and let it get rid of whatever it finds. Re-boot and then reactivate System Restore. You may want to Google "running two anti virus programs" and see what the experts have to say. Not one single one recommends it. For anti-malware, I use Kaspersky and A-Squared free ( now owned by Emsisoft), but neither have real-time scanning activated. I update both programs every day and scan with each about every two-three days. Norton 360 takes care of my firewall and anti-virus and has real-time scanning turned ON. I do full system image backups every three days ( using incremental method) so I have no need to have System Restore turned on. It's a waste of HDD space and not necessary. My suggestion----if your ISP does not provide a free (premium) security package, then I would give in and purchase Norton Internet Security. On all the sites that do independent anti-virus program testing, Norton tops their lists.
