I have a Dell computer running Windows XP Pro, version 5.1 (SP3). I recently received a Trend Micro report stating an infected file had been flagged. I have no file that I know of with that name, but ran a search anyway and turned up nothing. I then ran Malware and came up with 299 infected files. My question is: 299 infected files sounds like a huge number to me. Is it? If so, is there a simple explanation why I would have this many potentially problematic files?
The reason you couldn't find that file was probably due to it being part of your Internet browser cache file, and these files are usually hidden and not covered in a typical file search. Use the Search options, Advanced options in file search next time to include hidden or system files/folders. You should not be getting such a large return of potential problems from Malwarebytes continuously. So make sure your Trend Micro AV is up to date and before you pay for a new subscription, consider using Microsoft Security Essentials. It's free and works as well or better than the rest.
I have an HP Pavilion, running Widows Vista Home Premium. As long as I stay active online, all is fine. If I leave my desk for about 15-20 minutes, the computer drops off line, and I have to reboot to get back online. Is there a way I can disable what seems to be a timer of idle time?
It sounds like there is a power save setting kicking in for your network adaptor. Here's how to check if one is in effect and how to turn it off if it is: Run Device Manager in either of the following ways.
Click Start, Run, type devmgmt.msc and click OK. Or right-click My Computer, click Manage, then click Device Manager. In Device Manager, expand Network Adapters (double-click Display Adaptors). Right-click the adapter, click Properties. If there is a Power Management tab, click it and then clear the "Allow the computer to turn off this device to save power" check box.
If you don't see the Power Management tab, the network adaptor may still be part of the general Control Panel/Systems and Maintenance/Power options scheme. Lastly, it might also be controlled from the system BIOS. You enter the BIOS utility as your computer boots by pressing certain keys. This will be different for different computers (F2, F10 ...). Check your PC's documentation (online at the vendor's support site) to see if power settings are configurable and if the network adaptor is one of the options.
