I recently ran Disk Cleanup (with the "compress old files" option) and Disk Defragmenter on a PC with Windows XP. This computer was purchased in 2004, and was a "middle of the road" computer at the time. After using it, I tried to open a relatively new invoice file with "Simply Accounting" and it hung. I decided to restart the PC, and it then worked fine. I also installed and activated the Free AVG antivirus 9.0, and ran a virus scan (no viruses found).
- Did running Disk Cleanup, Disk Defragmenter, or Free AVG cause something to slow down file access for Simply Accounting? If so, will this be a permanent problem? If so, is there any way I can reverse it?
- Does Free AVG 9.0 being active cause reduced performance? If so, are there better free antivirus programs?
I appreciate any help you can offer.
